This channel is a real treasure chest. I am new to astrophotography and am learning so much here. I would love to see a video on how to take calibration frames. I have trouble understanding how many to take, what exposure to use etc… Keep up the good work.
Well, add to the list of fans Rich. Happy to have this stacking and processing program available to the masses of us who cannot afford some of the other ones out there. In this video, you show that Sirilic will combine the multiple nights of lights,darks,etc. Will Sirilic combine ONLY the light frames from the various nights if that’s all we collected? One of the scripts in Siril DOES allow this. Or must we have all the calibration frames as well? Keep it up, man. This is great!
Thanks! Great tutorial. A question though, why is the final file much smaller in size. A typical stack in Siril for me is usually over 100 mb and in Sirilic it’s only 11 mb.
@DeepSpaceAstro I figured out that it's because I'm using Ha instead of DSLR in the layer choice since I am processing data from a clip in Sii Max Fr filter. For some reason, the image pixel size is greatly reduced when using Ha.
Question - Would I want to use SiriLic when I have images using different filters? For example, I used my 533MC Pro camera on a 135mm Rokinon; one set of data was through an IDAS NBZii filter, the other set of data was through an Optolong L Pro filter. Not much data was collected, but it was collected on the same night. My guess is yes, use SiriLic.
Once again folks, these tutorials are fantastic. Good job! It would be great if you could do a video on the different options in the properties tab. Thanks!
Looking forward to comparing how my M8 image (4 nights of data) comes out using this method compared to when I just threw all of the files by type in single folders and edited the resulting stack in Siril and PS.
Thank you posting this. A couple of questions: is it ok to add a different set of data for the same object? For example, one night with 180 sec exposures at Iso1600, another with 60 sec exposures at iso800? What about focal lengths?
Great explanation of multi-session processing. I am on it right now, so far is going good (step 2 in progress). I found it's more complicated for multi-session processing than in DSS software, but with this explanation it is under control now. Thanks!
@@DeepSpaceAstro So I was successfully processed my three nights data though not without problems. In the first run (all settings default) it failed - just one of 500+ frames in registered sequence. Then I used Green channel for registering process (default is red) and it stacked properly. Then I had some concern at the end: how many frames have been stacked finally? I could not find this info in the SUMMARY displayed at the end of the processing. So I opened HEADER of resulted *.fit file (using SAOImageDS9) and found it there under STACKCNT. It can be helpful for some less experience people. Once again thanks for the tutorial!
I'm looking forward to trying this. I used AstroAF's video to install Sirilic on a Mac in a Python environment. I still had to make some tweaks beyond his video, but it's running now.
This is PURE GOLD, Rich. Question: I found a choice box inside Sirilic > Stacking to select "RGB Equalization". Do I want that? I'm shooting and processing from OSC camera (ASI2600MC-P). Thanks, again. Bob UPDATE: Found this single line in the documentation -- "If RGB equalization is checked, the channels in the final image will be equalized (color images only)."
I don't think it matters. When unlinked sometimes the autostretch will look green, but then you just click the link button. It'll all get balanced out with color calibration.
Can you process lights, darks, flats, dark flats without using bias? Or do you just move your dark flats into the bias section when setting up Sirilic? Thanks
Hi Rich, I received feedback from Cyril Richard regarding the warnings, the reason is that the possibility has been introduced in Siril to recognize the underscore as a separator in addition to the period and therefore generates this warning... a really curious thing... Ciao Roberto
Hi, what about separating Ha and OIII? I shoot with a L-enhance a lot and I like to separate them then composite them. Can I do that here with multiple sessions?
Thanks for the great tutorial. This one and others have been very helpful. I have stacked two sets of images and encountered a weird problem. The first was three sessions of the Pinwheel Galaxy which turned out fine. The second was two nights of Rho Ophiuchi which came out flipped vertically just like you flip an image vertically in Photoshop or GIMP. In fact after processing, I flipped it in GIMP to get it corrected. I have searched and find nothing in any messages about this. Do you have any idea what I screwed up?
Could you provide a link for iMac, I am totally new, and many friends advised to use Sirilac and Siril. A friend helped me to install Sirilic on my iMac 27in macOS Cataline (Late 2021) ver 10.15.7. But now done know how to start as there is no icon on desktop for it to click on.
Sorry I can't be much help as I'm not a Mac user. On Windows, there is no icon either. I just double-click on the executable. I suspect it's the same for Mac. Head over to @AstroAF here on RUclips. He's a Mac user a may be bale to help.
can you still stack multiple nights if your focal length changes a little ? iso ? aperture ? tyvm. just starting astrophoto and using zoom camera lens for now
I have a question I processed two nights of data worked perfectly but I can't find the integration time info after stacking anywhere. DSS tells me siril show your integration time. Am I just missing it somewhere? Thanks
Hello dude. U have been my 'tutor' since I jump into astrophotography. Thanks for good tutorial. Can I know if u have any video regarding dizzle when using sirilic? I cannot find it anywhere. Hopefully u can help me with it. Thanks again master !!!
another interesting Siril video tutorial Rich, thanks! About memory usage, I have espanded the RAM from 8 to 64Gb and now the stacking process takes less than 3/5 minutes, nothing compared to Pixinsight that require for the same images one hour and half... I have also the nVidia GTX950 2GB CUDA 5.2, do you know if can be possible to configure it to improve the Siril's performances, I'm thinking to Deconvolution and other process Thanks again Roberto
Thanks for all the terrific tutorials, Rich! I attempted to use sirilic to process one night's data using flat darks/no bias with good results, but it seems the stacking filter (roundness .9) was not applied as all images were stacked. Also the result did not apply RGB equalization even though the option was selected. When I use Siril alone this doesn't occur. I'm using Sirilic v. 1.15.8 and Siril v1.2.1. Any ideas?
Thanks so much. Glad they've been helpful. Unfortunately I'm not sure why that would be happening. You can review the script that Sirilic builds based on your selections, and see if it actually used the correct commands/parameters while referencing Siril's command line documentation. siril.readthedocs.io/en/stable/Commands.html#commands . I know that may be difficult, but it's the only thing I think to look at.
Very good video and advice, Rich. One question is: did your camera have the same orientation in all 3 nights ? I ask because its not easy to get the same framing in all the sessions, exact rotation and RA/DEC centering. Many thanks for your reply.
I don't see why it wouldn't. If the OS sees it, so should Siril & Sirilic. Keep in mind though it probably would be slower than using your internal drive.
No matter how much videos I watch I can’t figure out why siril doesn’t allow me to process my darks and flats. I’m a beginner. The moment I click the calib button both directories disappear. It won’t do anything. If anyone could help me I’d be sooooooooo thankful.
Mighte be able to help you, but I need more details. What "calib" button are you clicking? What OS? Can you describe more about the directories disappearing?
Another great video Rich 😁. I was wondering if when you stack multiple nights (potentially using different filters) whether this program has rejection software or whether all images selected will be stacked? For example, if I use my L-Extreme filter one night and just a UVIR cut filter the next with the same exposure time, the latter frames will have many more stars showing and so would the L-Extreme images all be rejected due to much less stars being detected? I hope you can advise. Cheers
SirilIC is just a frontend to the command line version of Siril. Once you add the images, and select your settings, it writes a script that's execute with Siril. You can view that script as well from the menu up top.
Nice one Rich, am I right in assuming you can stack using multiple data with different cameras or telescopes? I only ask this as I'd like to stack some data from last year with some I'm taking this year but using different cameras plus the orientations of both are different. Also can I stack without darks or bias frames as I tend to only shoot lights flats & dark flats cheers.
I'm pretty sure you can, but I've never done it myself. Any multi-night data that I've stacked was always from the same camera and scope. I've seen others collaborate so I have to assume they're not all using the same equipment.
Bonjour quand je télécharge sirilic j'ai la version V1.15.7 mes je ne trouve pas le mot de passe de je suis complément perdu pourriez-vous m'aider sil vous plait merci
hi, it doesn't work for me, siril version 1.2.0 and silrilic 1.15.8, I insert all the photos, lights, darks, etc., I press action first step, *** copy_link() :Command 'mklink "C:\Users\fede\Siril \Work\M33\RGB\S01\OFFSETS\SRC\Bias_1.2s_Bin1_294MC_gain120_20230516-153743_-9.4C_0032.fit" "C:\Users\fede\Siril\Work\1\Biases\Bias_1.2s_Bin1_294MC_gain120_20 230516-153743_-9.4C_0032.fit "' returned non-zero exit status 1. ***Symbolic Link Error on Windows: Check if the "Developer Mode" option is enabled Warning, Symbolic Link on Windows works only with NTFS partition I have NTFS partitions but the program crashes immediately. solved..... DEVELOPER MODE ARE DISABILITED......LOL
Quick question: is this also working without the BIAS and Flats? (Dwarf2) And if yes, what is the configuration for a Dwarf2 in CAMERA - also DSLR? Thx for your answer in advance!
It does. I configues itself to whichever sets of data you put into the program. but I'm confused how i search for a sequence to choose the frames to search for satellites and clouds
Thanks for the tutorial. Any idea if there is a way to configure it to run the Extract_HaOIII extraction pre-processing script rather than the default? Looks loike it may be possible in the actions menu but building and altering scripts is beyond me.
I just test it out with ** two nights session ** and it worked to extract the HA/OIII, But ... . The but is it only takes the files from the First night session. Ther second night just get ignored ! With that been said it looks like the HA/OIII scripts cannot take care of multi night sessions. To get the HA/OIII script, when creating a new project, select the Object name and number of sessions, but lower down you just need to select your camera type and put a check mark at ** Duo Ha/Oiii **. but as i said before it never worked for me with multiple nights sessions. (Tested with Sirilic 1.15.8 and Siril 1.2.0 )
Great tutorial! I deeply appreciate it! However, one question arises in my mind: Why are the bias files substracted from Flats? Shouldn't they be substracted from Lights? (Of course, not from both).
I know it's not ideal but if I decide to use just one set of flats for multi-night stacking, can I just do it all in Siril and not use Sirilic at all? So I would just put all the lights in the same folder and stack them as normal in Siril or will the different dates and times confuse the program?
Yep. I've done that before when I've left my mount and scope out for 2-3 nights. If you tear down between sessions, like you said, it's not ideal, but it should still align and stack.
Hi Rich, thanks for all the great videos; I am a Siril convert! I've also used sirilic for multi-night and even single night, great tool. Unfortunately recently, it doesn't execute in windows anymore. I went to the gethub/web to see if this is an issue for others but don't see any reports/fixes. tried removing/reloading but I think there is a registry conflict or hidden init/config file issue since its just an executable. Couldn't find how to ask the developer for suggestions and wondered if you might know how I might contact them. thanks.
@@DeepSpaceAstro Thanks, I resolved this issue by re-reading the manual (Duh right?) and found I had moved the sirilic script file in the working directory. once restored it launches correctly.
Great tutorial again. Success at first try simply just following your instructions. I do have one problem though, processing this way it gives an result where my red channel looks weird, very suppressed compared to normal OSC_preprocessing script. And I end up with noisier and more grainy result. Any ideas what that could be?
Hey Rich. Everything works perfectly through the "build directories and copy/link the images" but when I try to "run Siril script" it wont. I get the message ***Timout expired : Problem to run 'Siril --version' This seems to be a newer version of sirilic than in your video, some things look just a little different. maybe there's a bug.
@@DeepSpaceAstro Not that I can see. It seems to do everything fine up to that point. It creates a "script" in the working folder. One more thing it does is when I start to run the script it opens up an entirely new sirilic window, but the error message appears in a few seconds in the original window. BTW this is sirilic v. 1.15.2
This is fantastic! Question: Lets say on the initial night I took all calibration frames but on subsequent nights I only took flats, will this be a problem for the program or do you need an additional step? Been using Siril for about a week, have yet to use Sirilic except to download, open and follow along. Thanks
No, that should work. You could probably even re-use your darks and biases for the nights you didn't shoot them, assuming all of your sessions are the same exposures, ISO, etc.
Just trying this and get as far as tag#9 and red warnings about files cannot be opened offsets.seq darks.seq for both nights files then aborted. Any ideas what it might be?
Sorry, I'm not understanding where you're seeing the errors? Is it during the script creation or when when you run the generated script? Might also be better if you can paste the errors here including a few lines before and after that error.
Cant cut and paste to this tablet sorry i think my dslr\group folder contains no sequence as step 2 gets as far as merge then complains cant find various .seq files Error in line 136 merge generic error Seems to work great except for this part :( 98.61% :(
Although im running into one issue. Everytime i try to crop it will somehow remove data from my blue channel or all the channels. This also happens when I restack the images in siril. Any thoughts?
@Deep Space Astro it's weird. It'll stretch different channels just by cropping the image. Stetch it or just decrease the color bands amplitude. It results in the dso losing brightness. To the point where I can't see it no longer. I'm guessing you never heard of this problem before. Which is ok, just researching.
I am currently on a project with 12 imagers (myself included) shooting M106. We all use different focal lenghts and different filters. The total amount of lights has surpassed 384 hours of exposure. That is 16 full days of exposure. ;-) This video will come in handy processing the entire set of data. Almost 100Gigabyte.
@@DeepSpaceAstro I plan to create a video on it. But crazy time is slowly subsiding a bit for me so first thing is that AM5 video... Man that takes (me) long to make...
Hi, after stacking in dss, my file is 150mb, however if i use sirilic, file is 69mb, any ideas why its so different? is there a way to check how many frames has been rejected, or total integration time of stack? Thanks man
Not sure about why the sizes differ. I assume it's just different ways the 2 programs stack. Scroll back up through the log after Sirilic has completed. I know you can at least see how many images it stacked. That would at least allow you to figure out total time and number of rejected. You can see this in the video here for reference. ruclips.net/video/HJHz1dEy62c/видео.htmlsi=2voszMmvxUgAz7qq&t=1052
I followed your tutorial and when I did action 1 (to copy the files etc) I got an error message "... aborted: Siril requires a minimum of 2 light images". I tried adding the files in a different manner as well as unchecking symbolic links, all to make sure it wasn't a bug concerning those things. I'm on macos 10.13.6 and using Python 3 to run Sirilic. I downloaded all programs today, so they are the newest versions. Any ideas?
@@DeepSpaceAstro Yes. By a happy coincidence I actually figured it out a couple of minutes ago! When loading image files into my sessions i noticed that one session, in the work directory tab in the bottom left, never got an arrow where i could click to see how many files was in it. I realised it was always happening to the same files and it turned out that one of the folders leading to where i had my files had a very long name. After shortening that it seems to be working as it should. Fingers crossed I'll have my first image done soon!
Thanks for the video. Just in case someone has issues like me, where Sirilic was always aborting because after calibrating it could not stack. It gave an error that it did not had any stars. Somehow the calibration flats removed all the stars. I read in somewhere that: "Flats won’t work properly unless you subtract the bias from both the flats and the lights." So I just added the step to also substract the Bias to the images, not just the flats, like in the video, and I stopped having issues. It stacked just great.
This channel is a real treasure chest. I am new to astrophotography and am learning so much here.
I would love to see a video on how to take calibration frames. I have trouble understanding how many to take, what exposure to use etc…
Keep up the good work.
Thanks so much! I have a long list of videos I want to create. I'll add your suggestion to it.
You are fantastic! I'm just getting into Astrophotography and you are fantastic! I'm learning so much from you!!

Just what I was looking for. Brilliant tutorial. Many thanks
Thank you!
Man, awesome stuff dude. Thanks
Glad you liked it! Thanks!
Thanks! Great tutorial. A question though, why is the final file much smaller in size. A typical stack in Siril for me is usually over 100 mb and in Sirilic it’s only 11 mb.
Thanks so much. Could it be that you have Siril set to 32-bit and SirilIC is 16?
@DeepSpaceAstro I will check that, thanks. The final sirilic size looks more like 8 bit, so I will make sure then sizes are the same in each software.
@DeepSpaceAstro I figured out that it's because I'm using Ha instead of DSLR in the layer choice since I am processing data from a clip in Sii Max Fr filter. For some reason, the image pixel size is greatly reduced when using Ha.
Awesome video. Thank you 🖖🏼

Would you also do divide out not only by night shot but also by exposure time? I have 2-3 nights of imaging, but also 3 different exposure times
If the exposure times were considerably different, than yes.

This is PURE GOLD, Rich. Question: I found a choice box inside Sirilic > Stacking to select "RGB Equalization". Do I want that? I'm shooting and processing from OSC camera (ASI2600MC-P). Thanks, again. Bob UPDATE: Found this single line in the documentation -- "If RGB equalization is checked, the channels in the final image will be equalized (color images only)."

Can you process lights, darks, flats, dark flats without using bias? Or do you just move your dark flats into the bias section when setting up Sirilic? Thanks
That's correct. You only use Dark Flats or Biases, not both. So just put them in the Biases section.
Quick question. What preprocessing script options do we have in siril, once multiple sessions are stacked through sirilic?
Nothing changes if you stack with SiriLic. Process the image as you would if you stacked in Siril.

hi, it doesn't work for me, siril version 1.2.0 and silrilic 1.15.8, I insert all the photos, lights, darks, etc., I press action first step, *** copy_link() :Command 'mklink "C:\Users\fede\Siril \Work\M33\RGB\S01\OFFSETS\SRC\Bias_1.2s_Bin1_294MC_gain120_20230516-153743_-9.4C_0032.fit" "C:\Users\fede\Siril\Work\1\Biases\Bias_1.2s_Bin1_294MC_gain120_20 230516-153743_-9.4C_0032.fit "' returned non-zero exit status 1.

solved..... DEVELOPER MODE ARE DISABILITED......LOL
Quick question: is this also working without the BIAS and Flats? (Dwarf2)
And if yes, what is the configuration for a Dwarf2 in CAMERA - also DSLR? Thx for your answer in advance!
You should be able to just add your lights and/or darks from the Dwarf.
I have a Dwarf2 smart telescope and I don't take flats and biases. Does this script works with only lights and darks?
Possibly, but I haven't tried.
It does. I configues itself to whichever sets of data you put into the program. but I'm confused how i search for a sequence to choose the frames to search for satellites and clouds
Thanks for the tutorial. Any idea if there is a way to configure it to run the Extract_HaOIII extraction pre-processing script rather than the default? Looks loike it may be possible in the actions menu but building and altering scripts is beyond me.
Someone commented that it can do that already, but I haven't looked at it yet
I just test it out with ** two nights session ** and it worked to extract the HA/OIII, But ... . The but is it only takes the files from the First night session. Ther second night just get ignored ! With that been said it looks like the HA/OIII scripts cannot take care of multi night sessions.
To get the HA/OIII script, when creating a new project, select the Object name and number of sessions, but lower down you just need to select your camera type and put a check mark at ** Duo Ha/Oiii **. but as i said before it never worked for me with multiple nights sessions. (Tested with Sirilic 1.15.8 and Siril 1.2.0 )
Thanks, if you find a multi-session solution then please do let me know. Still haven't been able to work it out myself. @@benoitbreton5243
Great tutorial! I deeply appreciate it!
However, one question arises in my mind: Why are the bias files substracted from Flats? Shouldn't they be substracted from Lights? (Of course, not from both).
My understanding is they remove dark current from the flats. Without them, the flats would not be calibrated properly.
I know it's not ideal but if I decide to use just one set of flats for multi-night stacking, can I just do it all in Siril and not use Sirilic at all? So I would just put all the lights in the same folder and stack them as normal in Siril or will the different dates and times confuse the program?
Yep. I've done that before when I've left my mount and scope out for 2-3 nights. If you tear down between sessions, like you said, it's not ideal, but it should still align and stack.
Hi Rich, thanks for all the great videos; I am a Siril convert! I've also used sirilic for multi-night and even single night, great tool. Unfortunately recently, it doesn't execute in windows anymore. I went to the gethub/web to see if this is an issue for others but don't see any reports/fixes. tried removing/reloading but I think there is a registry conflict or hidden init/config file issue since its just an executable. Couldn't find how to ask the developer for suggestions and wondered if you might know how I might contact them. thanks.
I don't, sorry. There's an issue page here where you could report what your seeing. gitlab.com/free-astro/sirilic/-/issues
@@DeepSpaceAstro Thanks, I resolved this issue by re-reading the manual (Duh right?) and found I had moved the sirilic script file in the working directory. once restored it launches correctly.
Happens to us all! Glad you figured it out and thanks for reporting back.
Great tutorial again. Success at first try simply just following your instructions. I do have one problem though, processing this way it gives an result where my red channel looks weird, very suppressed compared to normal OSC_preprocessing script. And I end up with noisier and more grainy result. Any ideas what that could be?
Hmmm. Really hard to say. I assume you have calibration frames for each night that you're stacking? Thanks!
Hey Rich. Everything works perfectly through the "build directories and copy/link the images" but when I try to "run Siril script" it wont. I get the message
***Timout expired : Problem to run 'Siril --version'
This seems to be a newer version of sirilic than in your video, some things look just a little different. maybe there's a bug.
Are you using the latest version of Siril? Ver. 1.2.0-RC1 ?
@@DeepSpaceAstro I just checked and yes I am.
Any other errors or warning before that one?
@@DeepSpaceAstro Not that I can see. It seems to do everything fine up to that point. It creates a "script" in the working folder. One more thing it does is when I start to run the script it opens up an entirely new sirilic window, but the error message appears in a few seconds in the original window. BTW this is sirilic v. 1.15.2
This is fantastic! Question: Lets say on the initial night I took all calibration frames but on subsequent nights I only took flats, will this be a problem for the program or do you need an additional step? Been using Siril for about a week, have yet to use Sirilic except to download, open and follow along. Thanks
No, that should work. You could probably even re-use your darks and biases for the nights you didn't shoot them, assuming all of your sessions are the same exposures, ISO, etc.
@@DeepSpaceAstro Quick follow up. Did exactly what you mentioned [" re-use your darks and biases for the nights you didn't shoot them"] - worked fine.
@@darrellburke3108 Glad it worked out!
Just trying this and get as far as tag#9 and red warnings about files cannot be opened offsets.seq darks.seq for both nights files then aborted. Any ideas what it might be?
Sorry, I'm not understanding where you're seeing the errors? Is it during the script creation or when when you run the generated script? Might also be better if you can paste the errors here including a few lines before and after that error.
@@DeepSpaceAstro will try asap.. It looks like scripts after display the comment tag#9 cant find the seq files
Cant cut and paste to this tablet sorry
i think my dslr\group folder contains no sequence as step 2 gets as far as merge then complains cant find various .seq files
Error in line 136 merge generic error
Seems to work great except for this part :( 98.61% :(
Errors show up in sirilic log display btw
Really need to see what you're seeing to try and help
Although im running into one issue. Everytime i try to crop it will somehow remove data from my blue channel or all the channels. This also happens when I restack the images in siril. Any thoughts?
What do you mean it removes data?
@Deep Space Astro it's weird. It'll stretch different channels just by cropping the image. Stetch it or just decrease the color bands amplitude. It results in the dso losing brightness. To the point where I can't see it no longer. I'm guessing you never heard of this problem before. Which is ok, just researching.
It's stretching the image when you crop? Never seen that happen
@@DeepSpaceAstro yeah, only when I use sirilic
I am currently on a project with 12 imagers (myself included) shooting M106. We all use different focal lenghts and different filters. The total amount of lights has surpassed 384 hours of exposure. That is 16 full days of exposure. ;-) This video will come in handy processing the entire set of data. Almost 100Gigabyte.
Whoa! Would love to see the end result!
@@DeepSpaceAstro I plan to create a video on it. But crazy time is slowly subsiding a bit for me so first thing is that AM5 video... Man that takes (me) long to make...
I hear ya. Editing is the not so fun part of this RUclips thing. 😂
Hi, after stacking in dss, my file is 150mb, however if i use sirilic, file is 69mb, any ideas why its so different? is there a way to check how many frames has been rejected, or total integration time of stack? Thanks man
Not sure about why the sizes differ. I assume it's just different ways the 2 programs stack. Scroll back up through the log after Sirilic has completed. I know you can at least see how many images it stacked. That would at least allow you to figure out total time and number of rejected. You can see this in the video here for reference. ruclips.net/video/HJHz1dEy62c/видео.htmlsi=2voszMmvxUgAz7qq&t=1052
I followed your tutorial and when I did action 1 (to copy the files etc) I got an error message "... aborted: Siril requires a minimum of 2 light images". I tried adding the files in a different manner as well as unchecking symbolic links, all to make sure it wasn't a bug concerning those things. I'm on macos 10.13.6 and using Python 3 to run Sirilic. I downloaded all programs today, so they are the newest versions. Any ideas?
Not sure. I assume you have more than 2 light frames as the error is warning about?
@@DeepSpaceAstro Yes. By a happy coincidence I actually figured it out a couple of minutes ago! When loading image files into my sessions i noticed that one session, in the work directory tab in the bottom left, never got an arrow where i could click to see how many files was in it. I realised it was always happening to the same files and it turned out that one of the folders leading to where i had my files had a very long name. After shortening that it seems to be working as it should. Fingers crossed I'll have my first image done soon!
@@mistaskate8715 I had the same problem, and confirm that the problem is the path name lenght, copying the files in a "short" name it works
Thanks for the video. Just in case someone has issues like me, where Sirilic was always aborting because after calibrating it could not stack. It gave an error that it did not had any stars. Somehow the calibration flats removed all the stars. I read in somewhere that: "Flats won’t work properly unless you subtract the bias from both the flats and the lights." So I just added the step to also substract the Bias to the images, not just the flats, like in the video, and I stopped having issues. It stacked just great.
