Description

Although I imaged Andromeda last year, I was still very much learning the art of astrophotography (which will never end ofcourse). This year my goal was to literally crush that previous result. I think I did just that and I'm very happy to be at this point after 1.5 years of practice.



The image is an actual HDR composition consisting of the following exposures at ISO 1600;

- 95x 20 sec

- 80x 120 sec

- 21x 300 sec

Data was taken on 09-25, 10-04 and 10-05-2016.

edit: In the final version I left out the 300sec exposures as it introduced a few artefacts that I couldn't deal with properly. The combination of 20sec and 120sec proved to be the best.
