Really pleased that it helped you out. I have more videos planned for the future including some things on PixelMath too. I’d love to see your comet image too. Is it on social media anywhere?
Been having problems looking for a comet process for OSC cameras...Struggling with this monster for over a week. Your video was the first one that worked..! Thanks Mate! RB Florida USA
@@astrojourneyuk unfortunately, I went through all of the steps through ABE, but the comet image still has star streaks, as if the winsorized rejection didn't reject enough of the stars. Back to the drawing board...
Did any of the other pixel rejection options work? You can always mask out the streaky stars from the comet image and when you merge the comet with the static stars it should be good.
@@astrojourneyuk I haven't tried the other rejection options, but will try later today. I was also thinking using a mask could do the trick. I will play around with it later and see how it goes. Thanks again!
Thanks for the walk thru. I did the same steps as you and got the same results of the final image. I think the only way it could be better is if I imaged it from a dark sky site, but I did mine in my back yard with a quarter moon out, so the final image wasn't too bad, considering.
Thanks for watching and stopping by. I was hoping too for an Ion tail but I don't know if that's a focal length issue or a bortle 6 issue. I'll try again in 50,000 years from a dark sky site I think. :D
Great video. Very clear. I’ve just imaged C/2021 S3 (PANSTARRS), which is currently at magnitude circa 12, so a bit of challenge for my WO GT81. I’d be grateful for some advice :- Would you recommend the incorporation of SPCC and GHS into your workflow now ? Kind regards Mark
Great video! Thanks for taking the time to explain it all. When I do the comet align process by adding the debayered images, the end result has star trails still and the end image with pixelmath looks awful. Suggestions?
It’s odd how it’s an issue for some and not others. The other option is to do a star extraction on all the frames and then do a comet alignment and stack. Very time consuming but another approach that should work. Someone in the comments mentioned it so take a look back. Good luck with the processing.
Hi, trying to follow your tutorial. But I'm also new at PI. I stacked my image in Deep sky stacker, can I still follow your same process after you stacked yours?
I think the issue that you’ll have is that you won’t have registered images for the comet alignment. However, deep sky stacker does all this too so it’s worth looking for videos on comet stacking in DSS.
Great video. I'm not able to align debayred comet. Always get some crazy stack. But when I do it with registerd files,than is ok. I'm not able to find out what I'm doing wrong :(
Old fashioned method. Stars should be removed from comet images. Otherwise, star streaks will stay, and only way to get rid of them is clipping background.
@@astrojourneyuk Yes. There are now tons of videos about it. Original one was done by Adam Block 1 year ago. Star removal is very time consuming. For very good computer, Star XT will remove stars from single 11MPix frame for 5-7 min. So, don’t take more than 200 frames. One more thing. Your comet picture is not sharp. It moves 12” per minute. Your exposure depends on F number. My one is 500mm. Exposure no more than 15 seconds, 10 is better. Overall, 15x200 acquisition=50min max. Then, 10x144=24min. 10x90=15min. You will select best. Repeat every 8-10 days for different configuration of tails.
Great walkthrough, the only one I've tried so far which gave reliable results, cheers!
Fantastic, glad to hear it! Feel free to share a link to your image it would be great to see it.
Thanks so much for this, very useful indeed. First time using PixInsight as well, so good newbie lesson for myself.

That’s fantastic news! If only it works for everyone. There’s someone else messaging me where it didn’t work. 😢 You win some you lose some I guess.
Thank you very much!!! Really the BEST I could find about processing the C/2022 E3 in PixInsight!
That’s fantastic to hear that it’s been what you’ve needed. Thank you for the kind feedback.
great help thank you explained it really well
Fantastic, happy to help.
Great walkthrough! I've been waiting for a clear night to catch this one! Hopefully this Weds!
I wish you luck. I think I’ll not have much more of a chance now. Watch out for the moon! 🙈😢
@@astrojourneyuk Thanks! Yeah the moon is gonna cause me grief I just know it!
😢 It is at least on the opposite part of the sky but I’ll be surprised if it does impact things. We just have cloud now I think for at least a week.
Best tutorial on comet data processing I've found. Thanks so much! Going to try this out shortly on my comet data.
Thanks Daz, I’m glad you found it helpful and good luck with your processing. Let me know how it goes.

Great minds eh? 😀 Good luck! Let us know how you worked around the issues.
Super great! Thanks for a really good explanation video! Now I have something to do over the weekend with my comet data
Good luck with your processing and it would be good to see what you managed to capture.

No problem. Tag me on your image, I’d love to see it.

Are you using a colour or mono camera? I’m assuming colour?
@@astrojourneyuk Yes,colour camera
When you say a crazy stack, can you describe this further please?
Is pixinsight free?
It’s not free, however, there is a free trial which is fully featured.
I found the music distracting.
Ok, apologies for that. :(
@@astrojourneyuk With your accent, the music makes this video harder than it needs to be. I am having a very hard time understanding you.
@@mikevollmer8418 I’m sorry about that Mike. How’s my voice without the music? Where are you from by the way?
Just been wondering where are you from? Cuz english is not my native and I have no problems with understanding..
Old fashioned method. Stars should be removed from comet images. Otherwise, star streaks will stay, and only way to get rid of them is clipping background.
So remove the stars from every comet image before comet alignment and stacking?
@@astrojourneyuk Yes. There are now tons of videos about it. Original one was done by Adam Block 1 year ago.
