Can you post the raw images? Much can be told from the raw data, but processing muddies things. Could be alignment, or vignetting (very common). A very good start, at any rate.


Observing the Sun with complex optical systems since 1966, and still haven't burned, melted or damaged anything.
Not blind yet, either!
Light pollution? I only observe the Sun, magnitude -26.74. Pollute that!
