S.o.s. Andromeda, I ask for advice. sent on February 27, 2020 (8:18) by Inverno_Muto. 3 comments, 451 views.

at 200mm, f/7.1, ISO 1600, tripod.

Sono 8 foto in raw unite con dss o con sequator e poi post prodotte. Non sono ovviamente contento del risultato, ma dove sbaglio? Sono pose B che vanno dai 40 ai 100 sec astro inseguite. L'unica cosa che mi viene da pensare è il troppo inquinamento luminoso, ero in città.

I believe that in pp to eliminate the gradients derived from light pollution you have paved the sky floor and therefore the weak signal of the arms of the galaxy

f/7.1 is too closed for 100" poses I think, I at f/2.2 with single 4" poses without any chase I got this (from the sky of South Tyrol)

try to f/4, I do not think you will have problems of sharpness nor distortion at the edges.
Then, the post work can certainly change everything, but even if you don't see more details from the DSS tiff in the outlying areas of the galaxy, it means that you don't have that signal.
