Jerry Barnes Posted January 7, 2022 Share Posted January 7, 2022 About 6 hours of data, but poor guiding which I suspect may be the reason for elongation of the stars. I'm not sure yet if I should give up on the mount or try and sort it out. Always something to learn.... Autosave.tif 8 Link to comment Share on other sites More sharing options...
ollypenrice Posted January 8, 2022 Share Posted January 8, 2022 (edited) Gosh, no replies to this excellent image. Apart from the elongation it's very good indeed. Good colour, good light background sky with no clipping. There is a dodgy Photoshop fix for that kind of elongation. 😁 It's very simple: Make a copy layer. Change the blend mode to Darken. Go to Filter-Other-Offset and move one layer relative to the other along the line of elongation. In this case it's easy because it's vertical. I went for a 3 vertical pixel offset as shown... Before: After: If the elongation is not parallel with the chip you can rotate the image till it is, follow the procedure then undo the rotation. I should imagine that this will also be possible in other layers-based graphics programs if you don't have Ps. Again, what a good image.

teoria_del_big_bang Posted January 8, 2022 Share Posted January 8, 2022 (edited) Totally agree Olly an excellent image 🙂 As we actually had 2 clear nights for most of UK on Tuesday and Wednesday, probably a fair few images due to appear, will we get any more this January ??

Jerry Barnes Posted January 8, 2022 Author Share Posted January 8, 2022 Thanks, I appreciate the comments. I'll have a go with Affinity, I stopped my photoshop subscription as I didnt think I needed it. Link to comment Share on other sites More sharing options...
MKHACHFE Posted January 9, 2022 Share Posted January 9, 2022 Elongated stars?? Man alive, I dread to think what you would say about the stars in my images! Regardless, kudos to you mate on an absolutely stunning image. Great work. Link to comment Share on other sites More sharing options...

Maybe just leave it with the nice field of view you have? It hangs nicely. Edited January 10, 2022 by alacant Link to comment Share on other sites More sharing options...

Jerry Barnes Posted January 10, 2022 Author Share Posted January 10, 2022 Original data was 225 subs of 120 secs each in two sessions, I think I let DSS pick the best 75% of them. It didn't look any different to Pixinsight stacking all of them (at least not obviously to my eye). DSS is a lot faster for me. The framing wasn't quite right which is why I cropped the way I did but the original could grow on me after reading Alacants's comment. Link to comment Share on other sites More sharing options...
