This works when stars are all in the same direction, but trying to fix an issue with backfocus (yes, I need to add a .5 mm or so) where stars elongated pointing to the center. They really aren't too bad, but I know they are there ;)
Must have missed that. Had to start and stop recording of video a couple times. Might have reset it by accident. The general idea/how to is still there though.

Please consider subscribing if you haven't already. Thank you and clear skies!
Excellent Shan. Great short and simple explanation compare to the other. It works for me ;-)
Shawn, once again you save my bacon... this is great, thank you! -Bob
Thanks Shaun. Worked beautifully to fix eggs caused by some twisting in my image train (used GAME to select that areas I wanted to reshape).
this video was soooo helpful! All my stars were egg shaped and now are fixed! Thanks a lot VisibleDark!
You definetely deserve more subscribers...
I know! lol. Wish there was more. Thanks for watching! Clear skies.
Great video, works well, Thanks Shawn.
Another great tip Shawn. Thanks
Thanks for tuning in Logan! Cheers!
Excellent video. Thanks for sharing!
Glad you enjoyed it!
Thx for the tip! It really worked for me.
Great video. Thanks Shawn
Try the new BlurXterminator 2. Works really well for correcting egg stars.

Excellent Shawn! Thank you so much.
Nice, Thanks Shawn
You bet! Cheers
Great video ! do you know any way to reduce stars size witout using BXT ? Thank you so much
Thank you very much for that great tip. :-)
You're welcome!
When you went back to the motion blur tab, your angular adjustment was reset back to zero.

@@VisibledarkAstro Great video, nonetheless.
Shawn, please show how to fix halo in stars caused by NB filters please...Thank you!
Working on short video to show that. It certainly improves things a bit anyhow. Will share soon.
Works great, thanks!
Nice and useful
this is awesome, thank you!
Glad you like it!
As always, very informative! What method would you recommend to fix elongated stars coming from field curvature?
Could you use DynamicPSF and click on stars and look at the theta values to get a better idea of what a good rotation angle is?
yes for sure! That's a good idea.
Great tip! I will be using this a lot. When do you use this in the workflow? Thanks!
In the linear phase. Before noise reduction, and after background extraction
You want to use it early on really. Before you stretch the image.
Why on EARTH would I ever need THIS? *cough* 🤫
Haha! Did the giant egg catch your attention?
@@VisibledarkAstro That's an egg? I thought it was Alnitak.
Hilarious! Alnitak. 😂 Thanks for tuning in and leaving a comment. Appreciate that. Cheers!
Hentai eggs @Dylan O'Donnell.
Could that work with a mask for those stars that are elongated only in corners ?
I've not tried that but elongated stars in the corners can be solved with a field flattener and proper backfocus spacing. Clear skies!
Hi, dou you maybe know a way to fix egg stars in Photoshop? KR
There is a way but I honestly can't remember it. It's been so many years since I last PS for image processing.
I'm finding it improves star shapes, but increases noise in the background.
Is the image already stretched? I don’t see the green underlining on the tab name, which makes me think it is.
Should this be done while linear or non-linear?
Ideally it should be done before stretching.
Hello and thanks for your video! ((o:
Sometime I have stars "in different direction" in the corners. Do you have an idea what can I do to fit it?
I'm thinking you might need a field flattener for your setup. This will correct curvature in the corners that will distort your stars.
Is Pixinsight cheating ? I can apply Pixinsight to make an achromatic refractor exceed a 9000 dollar apochromatic refractor?
No mask?
