Description

After a way to long break it is time to get active again :-).

I am currently working on a new F4 refractor, the Pentax SDUF II. Finding the right backfocus is not that easy (and not specified either).
Therefore, stars are not good yet. Still need some more testing sessions, but the weather is bad as usual.

In any case, I wanted to do a full test on M31, which still has some issues in it since my processing skills got a bit dusty :-). The background was a bit to black and I messed up with deconvolution a bit, but I will save my efforts for when I found the proper backfocus.
The new equipment seems to be fine so I can continue working on this.

I hope to release more images soon again.
