First proper video explaining in detail. Made my fits look really good. Subbed!
Me too! I subbed
Thanks Chris. This is an excellent video for beginners trying to get the most out of their Seestar. Following this guidance has made a massive difference to the images I create.
This was such a good tutorial - thank you so much for taking the time to make this and for sharing your expertise
This was amazing, I just got my Seestar S50 and used this tutorial on my first imaging (30m on M33). Would love more tutorials on imaging, image processing specially GHS.
Great video, thanks! I had just captured some beautiful data on PacMan myself, with the very basic setup I have (StarAdventurer GTi and YES, I do put my Celestron 6SE on top of it, and my daily camera, the Canon 90D screwed behind it). And it surprises me again and again what is possible with this from my backyard! I had learned to install Starnet++ and REMOVE the stars in Siril, this gives me a beautiful look at the nebula itself, but never quite came around how you process the stars separately and then rearrange the two in Siril. Following your video showed me how easy that actually is! Thx for sharing!
For someone who is new, this tutorial goes so fast. One can not keep up with the constant (but necessary) selections of various tools with the arrow/cursor. I have to stop at almost every step to see where he is going. This took me over an hour to note each step, finding where the cursor went and what was being selectec, etc. Also, unless the starnet star removal tool is installed, the creation and editing of the star mask cannot be done, and he doesn't mention that, or how to get the tool. It would be much better at a slower pace. However, I still found it useful.
I just bought the S50. This video was the Silver Bullet that I was looking for. Thanks!
simple, clear and easy to understand explanations. Really, thank you.
Best tutorial I've found. Tried some others online but they were too fast and skipped over a bunch of steps. I was able to get a better image using your methods.
A great tutoroial - first one I've found that is easy to follow and gives great results with the Seestar S50
Glad it helped
My Seestar S50 was delivered on Thursday from FLO and I managed to image the Wizard Nebula. Not ideal conditions because of the 97% moon and Bortle 6 sky, but I was pleased with the result straight out of the S50. This video is just what I needed to now process the image in Siril. Thanks.
Hello Chris, thankyou for your patients with all of us learning Siril. The video is very instructional in many aspects and much appreciated. One thing i am really unsure of and would think it should be easily achievable but after all my attempting, i just seem to not to be able to achieve it. Object is M42 ... we all know it well. There is a particular part of this beauty that i always look to see and try to achieve which what i suspect is achieved by some of the better post processings. That is the trapezium part. First off, when I perform the starnet star removal on orion, funny enough the trapezium stars do not get included in the star mask fit. i suspect because the algorithm cannot detect those stars since they are already in a "hot zone" of bright nebulosity. but what do i know. perhaps there is a setting that can get this accomplished. in any event when performing the GHST or even the histogram transformation on the star less, i cant for the life of me have the nebulosity brighten without blowing out the core and wasting away the trapezium. I was wondering if you would be so kind to be able to put out a video on processing orion from that perspective or providing some tips. It seems to me that this task is so specific and involves both ends of the brightness scale that to be able to master that would put all of us on a great course to know what is required to tackle many other difficult transformations. But what do I know (just a beginner) Thank again Chris for all your great videos. / Ken
When doing GHST on the starless image, make use of the "Highlight protection point (HP)" slider to preserve the trapezium. It is one of the more difficult parts of post-processing, getting the right balance between preserving detail in bright areas whilst stretching the darker areas. The "Symmetry point (SP)" slider is also crucial to ensure you're stretching the right part of the image. Good luck!!
Thank you so much for these tutorials. I was so daunted by the interface on Siril I had no idea what to do. But after following your tutorial on a few images I’m getting images that are blowing my mind. Thank you 🙏
Glad I could help!
Thanks for another great video. This should help new users quite a bit. I always send them to your videos. I would add that selecting the Advanced button on the Star Recompostion window will make more stretch modes available, including inverse stretches, under a dropdown menu for Type of stretch. I find the inverse options very useful.
Thank you very much for all your effort! Certainly is of huge benefit having the process typed out on the RHS. 🎉
Great video. Just remember to add in the Starnet plug in before trying to do this!
@richardmarkham8369 how to add this starnet plug to siril? Could anyone tells, please?
@@SuperPavel21 Have you found out ?
Excellent guide! I'm new to imaging and this was a great introduction to the topic.
Good job, to reduce noise, use the second option in the list, not the first, works like a charm.
thank you greatly chris, you really helped me process my first image. it seems intimidating at first but once you get the lay of the land it is quite a fun experience. appreciate you pal. cheers from canada.
Bravo, new to all this. I just placed my order for a Seestar S50 so I'm guessing I won't have it until 2024, can't wait. In the mean time I will start following you.
Thank Chris for you time and effort in your tutorial, happy sky's.
Thanks a lot for this video and the clear explanation. I can use this to edit the fits files of my Dwarf II as well 👍
Glad it helped
Thank you so much for making this tutorial, its really going to help me with my Seestar processing.
thanks for sharing your workflow, much appreciated
Thank you for your two tutorial for processing Seestar images in Siril. Any more would be greatly appreciated. Thanks for sharing.
Sure thing!
Thank you so much for the excellent explanation. Even I can follow that workflow.
Brilliant tutorial! Can’t wait to try it on my fits. Thank you!
You're so welcome!
Amazing. Been fiddling around with Siril for a little while and this is the best tutorial I’ve seen so far. Thank you!
Glad it helped!
Many thanks for the detailed process! I am still waiting for my Seestar S50 .... hope it will arrive this year.
But now I am prepared ;-)
Still don’t know how to get the files from the telescope to the computer. Its like everybody knows how to do this. Everybody except me.
Connect the usb cable from telescope to your pc and turn on telescope. Your telescope will appear as a drive and you have access to all the files and folders.
Are you using an Asiair? With the Asiair turned on and connected to your network, Open a folder on your PC, and change the directory at the top to \\asiair
If all you've got is the SeeStar and your phone or tablet, you can copy files from the SeeStar to your device, one by one. That's a pain.
If you also have a laptop or desktop computer, you can follow the SeeStar instructions for how to turn off Station Mode on the telescope, and have it use your local WiFi network. I could only get that part done from my iPhone, not my iPad. Once it's on your local WiFi network, then you can follow the SeeStar instructions to get the IP address of the SeeStar device and then connect to that IP address from your computer, via the SMB protocol. Then you can download the files in bulk.

amazing , nice to follow and learn the workflow -thank you !
Brilliant - thank you so much for this!
Thanks for the Tutorial I will watch it through another couple of times and have gained some more information.
Excellent tutorial. Thank you very much.
Merci, ce tuto est vraiment excellent.
What does DADDD stand for? Its in the list of steps in the description "14. Noise Reduction + DADDD".
Here wondering the same thing?
Thanks for this video and for the resources !!
Hi Chris, a great tutorial. Im hoping you can help me with a query? At Step 10 when i open my starless image, on certain images the nebula (back in linear mode) is barely visible and in generalized hyperbolic stretch using stretch slider, the colours in the nebular a not visible, not matter how many times I apply and redo the slider. If i change to auto stretch it appears, however not in linear.
For reference, the Rosette Nebula was the image.
Hope you can help. Cheers Rick
Thank you so much friend! This helped me so much 👽👍
Very good tutorial. If you could, could you leave a link to the GIMP file frame? I've looked for it in the past and couldn't find it. Thanks
Great video! However, when I try to do star recomposition it won't let me open a file for the background stretch parameter to combine both images. Simply put when I click the background stretch parameter to add a file nothing happens.
Ok so I have a Mac and have Siril on it. the problem I ran into is if I have more than 200 or so light photos my computer doesn't have enough storage and the script will stop when its almost done. I bought an external flash drive and have the photos on the drive. However when I go into Siril click the home button to pick the files I want to stack my usb drive does not appear. Any tips?
Sorry, I’m a Windows PC user.
Hi Chris are the images in seestar already stacked, if not how do I individually stack image for processing in siril kind regards Steve
I have another tutorial on stacking Seestar images in Siril - ruclips.net/video/8iL2bzewBrQ/видео.html
Thanks for the tutorial, excellent. Now I ask, will the newly saved files, PNG and/or Fit will generate a high-quality printed image? Thanks!
Thanks for sending me all the 20 10sFITS files. 1 Feb I think. I have made a YT using one of your FITS using Affinity Photo. Title is Astrophotography with SeeStar: Affinity Photo for FITS File Editing I would like to recognize your help. Can I mention your name on the YT description? Still waiting from China for my Seestar. Best regards
Are there similar instruction for how to use PixInsight on SeeStar files?
Lots of good information, but how do you rotate the image if it has been field rotated in Seestar during very long exposures........and hour or more? What I see when I open the .fit file in Siril is rotated at about 10 degrees with solid black top left and bottom right corners. Your thoughts..................
In Siril, use Geometry - Rotate&Crop. Or polar align your Seestar
Tried the Rotate&Crop, still leaves voidsl, also tried PS rotate and Gen Fill for the blank areas, does not come out great. Will look into polar align, as have a wedge for my Star Adventurer tracker. Thanks............keep the videos coming!
Thank you! 👍✨
1.2.1 release and downloaded, but i failed to load the fit files.
chris, i used see star to image ngc869, took the unstacked images, 241 frames and stacked them in siril. after processing the final image, it was not as good as the stacked version form the see star. the amount of stars in the siril version was far less than the stacked final image from see star. what did i do wrong.
In the StarNet Star Removal option I cannot execute. I get a message "no valid StarNet executable found in the configured StarNet installation directory. Check your StarNet installation and Siril configuration". Any help?
you need to download the starnet command line version and then point to the installation directory in the settings of siril
Thanks. Tried that but when I point to the executable file in the preferences/miscellaneous tab it tells me that I do not have permission to open the file. I checked the file itself and I have read/write permissions so not sure what the problem is.
The volume is too low. Had to read the transcript
do you have a link to the facebook group you talked about at the end?

@@tarbat thank you
What if the plate solving in SIril fails?
You could try ticking the Downsample Image tickbox. If Plate Solve fails, then when you come to colour calibrate, you'll have to use the standard Colour Calibration instead of Photmetric.
