Neat image you can see some of the granular surface of the sun as well as the batch of sunspots. Have you tried stacking a bunch of solar image to help reduce atmospheric turbulence?

If you stack be sure all images taken over short time. Sun rotates faster then one expects. I sent some to Zerene? when I had problems, pointed out it appeared images weren't same, they weren't😕😕😕

Hi JBRIII
I noticed that latest version of Winjupos now includes the sun for image de-rotation from video. I have used this routine in the past for Mars, Jupiter and Saturn and it works well. You still don't want to go too long as the very edge will blur a bit but the main body of the object will be clear, but several minutes of video shouldn't be any issue allowing >10,000 frames to be stacked.

Thanks; I had photos maybe an hour or so apart, just did not think!
