Description

First light of my new star adventurer: M31 from my inner city backyard (red zone).
Taken with an unmodified Pentax K5 II and a Tamron 70-200 F2.8 @ 200mm F4.
This was basically a test how long I could make the subframes before getting star trails. Moreover, this is my first image with a total integration time beyond a few minutes. In this case I tried 53x75sec subs and used 49 for the final image.
Afterwards I also tried 120sec subs which turned out quite good too, but then my camera ran out of power.
