Processing a Seestar FITS file in Siril 

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!

First proper video explaining in detail. Made my fits look really good. Subbed!

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.

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.

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.

Great video. Just remember to add in the Starnet plug in before trying to do this!

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 🙏

simple, clear and easy to understand explanations. Really, thank you.

This was such a good tutorial - thank you so much for taking the time to make this and for sharing your expertise

I just bought the S50. This video was the Silver Bullet that I was looking for. Thanks!

Thank you very much for all your effort! Certainly is of huge benefit having the process typed out on the RHS. 🎉

Thank Chris for you time and effort in your tutorial, happy sky's.

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.

Excellent guide! I'm new to imaging and this was a great introduction to the topic.

Thank you so much for making this tutorial, its really going to help me with my Seestar processing.

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.

thanks for sharing your workflow, much appreciated

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.

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.

A great tutoroial - first one I've found that is easy to follow and gives great results with the Seestar S50

Thank you so much for the excellent explanation. Even I can follow that workflow.

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.

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

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 ;-)

Brilliant - thank you so much for this!

Brilliant tutorial! Can’t wait to try it on my fits. Thank you!

Good job, to reduce noise, use the second option in the list, not the first, works like a charm.

amazing , nice to follow and learn the workflow -thank you !

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.

Thanks for this video and for the resources !!

Merci, ce tuto est vraiment excellent.

Amazing. Been fiddling around with Siril for a little while and this is the best tutorial I’ve seen so far. Thank you!

Thank you so much friend! This helped me so much 👽👍

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 👍

Thank you for your two tutorial for processing Seestar images in Siril. Any more would be greatly appreciated. Thanks for sharing.

Thank you! 👍✨

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.

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!

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.

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?

Hi Chris are the images in seestar already stacked, if not how do I individually stack image for processing in siril kind regards Steve

Are there similar instruction for how to use PixInsight on SeeStar files?

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.

1.2.1 release and downloaded, but i failed to load the fit files.

What does DADDD stand for? Its in the list of steps in the description "14. Noise Reduction + DADDD".

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 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?

How can you get the Gimp overlay?

do you have a link to the facebook group you talked about at the end?

What if the plate solving in SIril fails?

How did you make the overlay as I use Photoshop?

How do I get the overlay?

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
