This is a cropped version of my Omega Centurai image I took the other day.

I noticed on the edges of the photo the stars look warped. I was using my telescope in my signature below with a focal reducer and a 1200D.

Any idea why this would be?

Also I took a photo of the Trifid and noticed there was a reflection which was Mars. I don't have the photo with me but wanted to ask what the problem could be.

Would like to know if I can fix it too!
