Description

Had to stay up until 1am to get this galaxy rise over a tree in the east. Very pleased with the quality of the subs even though guiding was still around 2'' ... seeing is terrible at the moment, star jumped around a lot

B

Levels and a bit more noise reduction

C

Wasn't happy with the last iteration, redid again, milder noise reductin, difference layer to get rid of the light pollution

D

Still not happy... ISO 800 is too much noise for this galaxy...

E

Added 8 more 20minut subs and took only the 30 best from the total stack

F

Nope, way too bright... I need a good rule of thumb for the correct background color ... Anyone has a good hint?

G

Following my new background rule and decided to denoise a bit more

H

While we are at it ... stars smaller and removed the red bands in the background

I

Less noise reduction, completely redone

J

Brighter Galaxy
