Astrophoto: Intergalactic Wanderer – Caldwell 25 – 02/23

My very first astrophoto with my mobile Astrophoto-Camp.

An evening with some blacks and whites. This was my very first evening on the field with my mobile battery power supply.

It was a bit annoying, that i forgot a part for my guiding cam. Luckily I could use a spare part of a friend for some time before he needed it himself. That way i was able to get 30 minutes of exposure time.

The final result was not more than acceptable. But since the evening was very special to me, I wanted to have a result.

Session Analysis

You can clearly see the time with tracking here. It was quite windy – I was able to use 4 out of the 5 frames. From the relatively large number of 60-second exposures without guiding, the rejection rate was quite high, so I only included 10 images.
