Rodd Posted December 27, 2022 Share Posted December 27, 2022 I determined that the terrible star issues I was having with this image were due to problems with alignment. For some reason, subs were not registering. When I blinked the registered subs, the stars jumped around like crazy. I reregistered making sure all subs aligned properly. Sure enough, the star issues were gone. I also tried Blur exterminator for the first time to fix issues like coma and tilt and other things it is supposed to be good for. I spent all day trying to reprocess the non stellar portion of this image and just could not do it. So I removed the stars from the original and replaced them with the repaired stars using Star exterminator. But first, I used blur Exterminator to sharpen the image. I know it works better on linear images, but it seemed to do a respectable job on the stretched version. I did it to the starless image before adding the stars, which is supposed to help. Some might think I overdid the sharpening. But Not by much. FSQ 106 with .6x reducer and ASI 1600. About 9 hours, 3.5 of which were Ha (I only used a little in the background) 9 Link to comment Share on other sites More sharing options...
Rodd Posted December 27, 2022 Author Share Posted December 27, 2022 And here is a respectable Running Man. I previously posted this as “Gumby on the move”, or something. But I removed it from my library due to terrible star issues. This one is much better 4 Link to comment Share on other sites More sharing options...
alan potts Posted December 28, 2022 Share Posted December 28, 2022 Stunning work Rodd. I have to ask why are you getting spikes on the stars in the Running Man shot, which I assume is a crop. Alan Link to comment Share on other sites More sharing options...
