I made a mistake in the Sirilic section. I should have gone in to the ‘properties’ section of the Flats tab, and checked the box to subtract bias. I thought this was on by default, but it’s not. Thanks to Alan on Patreon for pointing this out. And another mistake. I thought pip was installed by default on MacOS but I was wrong. I think I installed it when I installed Anaconda (scientific python package) on my Mac. Anaconda is a large download, but they make a smaller version called miniconda. You can install the m1 miniconda package from here: docs.anaconda.com/miniconda/ and that should install python/pip on your Mac, and then the installation instructions for Sirilic should work. Sorry for the confusion!
THANK YOU, great tutorial... I wish there was a complete solution like NINA with its Three point polar alignment plug-in but for macOS 😓 PHD2 and ASTAP are available for macOS tho.
BINGO!! That miniconda install did the trick; I am now fully Sirilic. I will note, however, that I can't open Sirilic from Spotlight but need to run it from the Terminal window; it must be something specific to Miniconda vs. Anaconda, or maybe Intel 'conda vs. Silicon 'conda (I'm running Catalina on an Intel Mac), but realistically that's a minor inconvenience. Thanks, Nico! I'm looking forward to your opinion of the Askar 71F.
I like that the process diagram indicates exactly this. There are no arrows from your bias frames indicating it creates the bias master but does nothing with it. What a great bit of software, the developer didn't need to do that, but they did and that's a lovely quality of life bit of work.
Hello, I am the author of the Sirilic software. In 2018, I wrote a piece of python code to facilitate my image processing. At the time, I didn't think Sirilic would be used by so many people. Thanks for this video
For the first time I tried downloading and processing your data. And HOLY CRAP! Within half an hour from downloading the data from the second night I had a great looking image (at least in my opinion). It's so much easier and faster than stacking the 1000 2s exposures and fighting the noise at every step processing that I have to do with my own data.
it's like you read my mind, i've been looking for a video like this. Your explanations are amazing. Thank you so much for such a seriously helpful video, Nico!!
This is an excellent and valuable video, thank you Nico! The very detailed section on stretching strategy is particularly useful, as it sometimes feels a little arcane. You made it very practical, thank you.
I really enjoyed that Nico. So many different approaches to Siril that I’d never seen before. I also like the part of the tutorial that uses Sirilic which I have used on Windows, but it’s a great refresher. I did spot your ‘mistake’ with the Flats, which you quickly highlighted 😂. Thank you for your time preparing this 🤝
Thanks, I've been using Siril and Sirilic, but altering the colors has been very difficult in Siril for me. You showed some neat new tricks to try out. Nice overall summary.
Excellent video Nico! I'll be rewatching it a few times because there are some little details I was never aware of in Siril! Good explanation and easy to follow! I would make a couple of suggestions: When stacking with Sirilic, you need to tell it to subtract the bias master. If you look at the flow diagram, the master flat and master dark are applied to the image, but the master bias is not. You have a checkbox in the project parameters to subtract bias and that needs to be enabled. When doing GHS, I would also try it in Human Weighted as slit sometimes improves the colour and I find the logarithmic scale to be better in showing if any of your RGB channels are over or under stretched.
I recommend you use an ssd when processing. I made the mistake of, by default, leaving it on my hdd instead of ssd and it went from taking about 1-2minutes calibrating 2-300 images to 30ish minutes. The hdd will be botleneck #1. If storage is a concern, delete process data once finished. Will use about 50-75GB on average for me, but you can clear the process data. I keep all my images for later use but this is not necessary if you plan to retake them again with other equipment later.
One other note: Not only do you have to have the Siril app installed, you have to point Sirilic toward your Siril app (or executable) in the Python Preferences, otherwise Sirilic doesn't know where to find the Siril scripts. That had me scratching my head for a few minutes, wondering why it wouldn't run. Open Python Prefs, and click the "Default" button opposite the "Siril Executable" window (top of the prefs pane, under Work Directory), and you're good to go - Python may or may not select your Siril installation by default.
I'm curious what you'd think, next time you go to stretch try stretching Andromeda in human weighted luminance for the color stretch! I find it really brings the color of the galaxy out without having to touch the saturation much!
Couple things, I started using Sirilic a couple months ago and it really made my processing a lot more enjoyable. It is a lot easier than preprocessing each night individually and then stacking everything together. I have also found that Siril works faster on Linux (not sure about Mac) than Windows because Windows doesn't support symbolic links. That also means that in Linux it doesn't take up quite as much intermediate space. I did also enjoy the processing... process? Anyway, there were a couple moment where I was like "Hmmm don't know about that" but I just waited and was rather pleased at the end. Though, just personal preference, I usually only increase the saturation in my images until I'm happy with the saturation of the star field and I leave the main DSO alone
Windows supports both symbolic and hard links, or rather NTFS does. It's a limitation of the program, Siril, rather than a failing of the OS in this case.
Ive been using sirilic for a while now, one thing I encountered was when I use images from my Canon DSLR I have to convert them into .fit files before I can add them into Sirilic. Hopefully in a future update they add handling that file type automatically
Great video as usual Nico. A quick question though. Rick at Deep Space Astro did a similar video some time ago, but if I remember correctly, he modified the process diagram so biases were subtracted from flats by going into Properties>Flats and the ticking the bias subtract box. So I've been using that approach without really understanding what I'm doing. Which is the most 'correct' approach do you think? Cheers
when you use sirilic you don't need to open siril (just enter siril folder on properties), it's very quick for preprocessing comparing to pixinsight and astrometry work better.
Hey Nico. Question. Since M31 is usually done with different exposures times to keep the core from blowing out, is that no longer needed if you're using the brightness protection slider in Siril? I noticed you didn't shoot shorter length exposures and use the HDR method. Thanks.
Your green histogram/green noise removal trick is that just used objects that have some brown and yellow? With targets that have a lot of red you wouldn’t use this trick?
Yeah I think it’s mostly useful for galaxies where aesthetically we want a blue boost. Not necessarily the best way to do it, but I’m a bit improvisational when it comes to processing, and my Siril knowledge is not as strong as my Photoshop knowledge. I deliberately kept this workflow to just Siril and Sirilic to keep it free.
How did you get these two desperate processing windows for the starmask and starless image? When I'm running StarNet I get two different images that are saved on my PC, which I have to combine with PixelMath Nice video, thanks :)
I see Siril 1.4 is on the horizon, a couple of channels have made videos of the upcoming changes. I'm wondering if Sirilc will keep up with the changes since it seems to be developed independently of Siril. Since upgrading to Siril 1.2.5 for MacOS I noticed after a multi session run, Sirilic failed to open Siril with the completed file. I had to open Siril and then the stacked Siriilic file. It would be awesome if Siril incorporated Sirilic since it appears Siril 1.4 will have a way to run Python apps What other software whould you recommend for multiple sessions besides Sirilic. If it's Windows only I use Parallels running Windows 11. It seems most of my imaging is now over multiple nights so I need something like Sirilic but I'm concerned about the maintenance of Siril. I notice Sirilic documentation is not very detailed. Thanks
Free on Windows: Deep Sky Stacker handles multi-session pretty well with the 'groups' option at the bottom of the interface. Paid (multi-platform): AstroPixelProcessor and PixInsight both have semi-complex user interfaces, but have the most flexibility for multiple imaging sessions that I've seen. I personally use PixInsight for big multi-night projects because of all the flexibility available.
Appreciate the detailed breakdown! A bit off-topic, but I wanted to ask: My OKX wallet holds some USDT, and I have the seed phrase. (behave today finger ski upon boy assault summer exhaust beauty stereo over). How should I go about transferring them to Binance?
Ok, new to a lot of this and not up on the coordinate system...........I live at 30 degrees latitude, how do I calculate how high and object will be above my horizon using its declination? Any help would be greatly appreciated!
I’m no expert but you should be able to just search your target and click it. In my past experiences in Siri, it should automatically enter it for you. Let me know if you figure it out
@@BM83222 Found a formula on the British website - BBC Sky at Night Magazine. Works for calculating the max altitude an object will reach for planning purposes............I then use Stellarium's measure tool to see where it would be at any given time and date. The way to calculate max altitude is: The maximum elevation of the celestial equator for a particular spot is: 90 - LAT. So for an observer at the latitude of London (51.5 N), the maximum elevation will be 90 - 51.5 = 38.5 over the southern horizon. Then add (for north declination) or subtract (for south declination) the tabulated declination of the object you want to view. Say you want to know the maximum altitude that the Andromeda Galaxy M31 will reach. Look up the declination (more or less 41degrees N) so it will be 41 degrees above the celestial equator i.e. 79.5 degrees altitude at most. Clear Skies!
I do it both ways (stretch->starnet, starnet->stretch) I haven’t really developed a preference. I chose to do it the way I did for this tutorial because I wanted to show the inverse stretch trick on the stars.
When you shoot multiple nights of the same object, are the settings same for all nights? I am a newbie and thinking of capturing multiple nights of M31, using a stock full frame mirrorless.
The best DSLR for astro is the one you already own. So if you a 5D Mark IV go for it! But I wouldn't buy it specifically for Astro. At the price those go for just buy dedicated Astro camera.
Nice, question . So what do u do with ur pictures, do u sell the pictures.¿. Or is just a hobby, I see that way to many ppl do this. What’s the market for this hobby thank your
I do print them out and have recently started selling them: ruclips.net/video/6teO7e6EhBk/видео.html I would say it is very tough to make a living on selling prints. I’ve been able to make the hobby my full time gig through support on Patreon because people like the educational RUclips videos. I didn’t plan for that and had a regular job as an astronomy librarian until recently.
Hey Nico, guess what? Yep, it is Question Time, lol. So, we all talk about imaging equipment, but could we discuss processing equipment? So, what is ok vs ideal computer requirements when running all these different software programs?
Ok would be basically any modern computer (past 10 years) if you are willing to wait long enough. Ideal in order of importance: 1. Working directory should be on a fast SSD with plenty of space. If the SSD has a fast read/write speed like a NVME SSD that will be even better. 2. Newer processor (CPU), more cores the better 3. More RAM. On windows, 32GB will work for most things, but 64GB or 128GB would be ideal.
@@NebulaPhotos Great! So, what about the graphics card? Is there an ideal memory for that? On my desktop, my photoshop will not allow me to use the camera raw filter and i get a window popup that says something about GPU Acceleration. Yet, everything in photoshop works fine on my laptop.
@@NebulaPhotos hey nico, this is off topic, but when it comes to the comet tsch-something...the one you can see now, how can you image it without your image being washed out from the dusk/dawn sunlight?
I'm falling at the first hurdle with my own data of M31. I'm using a D20 Canon DSLR, PCC can't plate solve my image, I've entered the RA and DEC and tried all the servers and catalogues, no joy.
Thanks I'll give that a try later. One question still nags me, are we pulling the colours from our data, or is the data being manipulated by other people's photos. I've done a few stretches and got some brown/orange showing through but nothing near the levels your getting.
I have MacOS 14.5 Sonoma running on a 2023 MacBook Pro M3. I had an older version installed.I downloaded the latest Sirilic .whl file and placed it in my folder named Sirilic. In Terminal I navigated to that folder. The command "pip install" is not found. If I try the command "python --version", it is not found. If I try the command "python3 --version" then I get "Python 3.9.6" returned. If it use the install command "pip3 install sirilic-1.15.12-py3-none-any.whl" the Sirilc application is installed. It first removed version "sirilic-1.15.11". The install is successful but when I type in Sirilic in Terminal while I'm in the folder I get an error "zsh: command not found: Sirilic". In previous attempts to install and run Sirilic I discovered I needed to enter this command in Terminal first "path=/Users/myusename/Library/Python/3.9/bin". Once I did that and enter "Sirilc" the program starts up. If I quit Sirilic and try to start Sirilic from the Search window like you demonstrated in this video and enter Sirilic all it does is take me to the my Sirilic folder, it never starts the Sirilic python application. If I change the name of the folder so it doesn't have Sirilic in the name then the search only finds the Sirilc website. Search doesn't know that it needs to open Terminal to try to run Sirilc.. The only way I can open Sirilc is to open Terminal, enter the path command, then enter Sirilic. Why is your install different and easier? It sounds like your MacOS version has python installed instead of python3 like mine. It is what came with my MacOS. Unix is not my forte so this is as far as I wanted to go. Thanks for this video;
This is great information. I don’t have all the answers yet, but I’m going to try to figure it out and hopefully make a follow-up as it’s clear I underestimated how easy Sirilic on MacOS truly is, based on the feedback I’m getting. Thanks again for the detailed report!
The youTube channel AstroAF has a video of installing Sirilc on his M1 Mac. He used a workflow of installing Homebrew, which is used to install Python. He uses the python3 --version command to verify which version of Python gets installed. Then he uses the pip3 install command to install Sirilic. I remember trying this procedure and had the same issue with the path not set up. Some research indicated that MacOs came with Python. Also there is a Python website with newer versions of Python3. I don't know if using one of those installers sets up a new path. I haven't tried it because if I get into some sort of trouble my Unix knowledge is limited. When you type in the python --version or python3 --version commands what is returned? Thanks
Also I Noticed Your Galaxy Looks Like It's Bend From One Side (left side after you rotate). Might be my eyes but doesnt seem right & considering its 2 days data, the arms are very less visible comparable to your previous m31 work
Oh darn, I really thought pip was standard on macOS, as I don’t remember ever having to install it on mine. Try: sudo easy_install pip Before the rest of the tutorial edit: I heard from someone else that this didn’t work on their M1 Mac. If the above doesn’t work, another way around this is install the m1 miniconda package from here: docs.anaconda.com/miniconda/ and that should install python/pip on your Mac
If it’s asking for a password during installation, I’d guess that is your computer password (same as for logging in to windows). Let me know if I’m off-base and I can look into it.
well, you can just buy a cheap telescope and see them for yourself. If you don't want to, then you can actually go to a dark site and see Andromeda with the naked eye or some binoculars.
I made a mistake in the Sirilic section. I should have gone in to the ‘properties’ section of the Flats tab, and checked the box to subtract bias. I thought this was on by default, but it’s not. Thanks to Alan on Patreon for pointing this out.

Wow was this a very thorough and thoroughly enjoyable tutorial! I think this is the best Sirilic / Siril YT I have ever seen - Thank you!
It's appreciated that you show how to get the job done with different software and different equipment.
YAY! Siril! Thanks Nico. Multi Night Stacking - just what I was looking for. Great job. You are AWESOME!

An incredible amount of information in this one video. Thanks!
I dont use any of this software in my workflow but still going to watch all of this. Never know what you might learn!
Great and amazing video Nico, like always!!! Too much thanks !!
Excellent video Nico! I'll be rewatching it a few times because there are some little details I was never aware of in Siril!
Good explanation and easy to follow!
I would make a couple of suggestions:
When stacking with Sirilic, you need to tell it to subtract the bias master. If you look at the flow diagram, the master flat and master dark are applied to the image, but the master bias is not. You have a checkbox in the project parameters to subtract bias and that needs to be enabled.
When doing GHS, I would also try it in Human Weighted as slit sometimes improves the colour and I find the logarithmic scale to be better in showing if any of your RGB channels are over or under stretched.
THIS CAME AT LITERALLY THE PERFECT TIME! THANK YOU 🙏🙏🙏
Did you read my mind? That's exactly the next project I want to do. With Siril and everything!
Thanks Nico, excellently explained. Boosted my motivation to try to improve my thusfar poor skills.
Excellent tutoriel, spécialement pour la partie consacrée à l’étirement hyperbolique généralisé.
Great tutorial, excellent job, thanks!
I recommend you use an ssd when processing. I made the mistake of, by default, leaving it on my hdd instead of ssd and it went from taking about 1-2minutes calibrating 2-300 images to 30ish minutes.

Yes, you can

The companion galaxies to M31 are already included in this photo. You would need a massive telescope to do closeups on them.

Try draw a box around your object and try again. I dont know why it fails, but when my ppc fails its because object is not placed center of the image
Thanks I'll give that a try later. One question still nags me, are we pulling the colours from our data, or is the data being manipulated by other people's photos. I've done a few stretches and got some brown/orange showing through but nothing near the levels your getting.
👍👍👍
I have MacOS 14.5 Sonoma running on a 2023 MacBook Pro M3. I had an older version installed.I downloaded the latest Sirilic .whl file and placed it in my folder named Sirilic. In Terminal I navigated to that folder. The command "pip install" is not found. If I try the command "python --version", it is not found. If I try the command "python3 --version" then I get "Python 3.9.6" returned.
If it use the install command "pip3 install sirilic-1.15.12-py3-none-any.whl" the Sirilc application is installed. It first removed version "sirilic-1.15.11". The install is successful but when I type in Sirilic in Terminal while I'm in the folder I get an error "zsh: command not found: Sirilic". In previous attempts to install and run Sirilic I discovered I needed to enter this command in Terminal first "path=/Users/myusename/Library/Python/3.9/bin". Once I did that and enter "Sirilc" the program starts up. If I quit Sirilic and try to start Sirilic from the Search window like you demonstrated in this video and enter Sirilic all it does is take me to the my Sirilic folder, it never starts the Sirilic python application. If I change the name of the folder so it doesn't have Sirilic in the name then the search only finds the Sirilc website. Search doesn't know that it needs to open Terminal to try to run Sirilc.. The only way I can open Sirilc is to open Terminal, enter the path command, then enter Sirilic.
Why is your install different and easier? It sounds like your MacOS version has python installed instead of python3 like mine. It is what came with my MacOS. Unix is not my forte so this is as far as I wanted to go.
Thanks for this video;
This is great information. I don’t have all the answers yet, but I’m going to try to figure it out and hopefully make a follow-up as it’s clear I underestimated how easy Sirilic on MacOS truly is, based on the feedback I’m getting. Thanks again for the detailed report!
The youTube channel AstroAF has a video of installing Sirilc on his M1 Mac. He used a workflow of installing Homebrew, which is used to install Python. He uses the python3 --version command to verify which version of Python gets installed. Then he uses the pip3 install command to install Sirilic.
I remember trying this procedure and had the same issue with the path not set up. Some research indicated that MacOs came with Python. Also there is a Python website with newer versions of Python3. I don't know if using one of those installers sets up a new path. I haven't tried it because if I get into some sort of trouble my Unix knowledge is limited. When you type in the python --version or python3 --version commands what is returned? Thanks
@@KJRitch Thanks for sharing this! I have a M1 Mac and the AstroAF method was the only way I got Sirilic to install successfully!
Also I Noticed Your Galaxy Looks Like It's Bend From One Side (left side after you rotate). Might be my eyes but doesnt seem right & considering its 2 days data, the arms are very less visible comparable to your previous m31 work
Which previous m31 work? I’m not seeing anything unusual about the arms here
Installing sirilic the way you showed doesn't work on my MacMini M1. Command unknown...
Oh darn, I really thought pip was standard on macOS, as I don’t remember ever having to install it on mine. Try:
sudo easy_install pip
Before the rest of the tutorial
edit: I heard from someone else that this didn’t work on their M1 Mac. If the above doesn’t work, another way around this is install the m1 miniconda package from here: docs.anaconda.com/miniconda/ and that should install python/pip on your Mac
how do you get the password for windows Sirilic ?
If it’s asking for a password during installation, I’d guess that is your computer password (same as for logging in to windows). Let me know if I’m off-base and I can look into it.
@NebulaPhotos found it for windows the password is sirilic. Says it is password protected as some antivirus software won't allow it to run
Ah, thanks!

Fantastic video, super helpful. As always. PS Please SIT ON YOUR HANDS! 😉
Amen!
No, really don't!
обработка полная хрень, если честно
nebulas and galaxies doesn't exist in reality they are just added with the computer when stacking
well, you can just buy a cheap telescope and see them for yourself. If you don't want to, then you can actually go to a dark site and see Andromeda with the naked eye or some binoculars.
Wish my computer did
U can literally see them with ur eyes 😂😂
What. Nahhhhhhh. They really are there.
