Hi,
I am a nightscaper, and I recently took a photo (as attached - I have reduced the size so the quality has dropped, but it wont let me upload the original) of the carina nebula area. There is a large concentration of stars in this area. I only just purchased a 135mm and I noticed bloating of stars in parts of the photo. So, I tried again a different night assuming that perhaps I was slightly trailing, only to find the exact same problem.
So I used my 135mm on a different target, only to notice that the stars are pin-sharp.
I guess I wanted to ask whether it is common to experience bloating and other challenges with the stars when taking a photograph of the carina nebula area? That way I wont feel so frustrated
