B

Stretched a bit further

D

Deconvolution and more natural colors

E

Wider field, natural colors, different noise reduction and dynamic range.

F

I did a whole re-processing using different weighting during integration, different drizzle settings and noise reduction

I

I ran the previous re-integrated version through Light Room to enhance details and colors
