First go at Centaurus A Galaxy & Sombrero Galaxy

Finally I found the time to setup the scope after the long move from the (liquid)Sunshine Coast QLD to the Hunter Valley NSW, our new house is just far enough away from the lights of town to have a very dark sky.

This time I tried to do PEC training on the RA & DEC drives this gave a slightly better result with tracking but I really need to do several updates to minimise periodic tracking error a little more.

Same stats for both Centaurus A Galaxy & Sombrero Galaxy, I think I stretched the curves a little too much in the processing.

90 x 25sec subs at ISO 1600 (total 37mins alt/az no guiding)
NO darks or flats (I was just testing the setup)
12 " LX200 (alt/az setup)
Sony Nex-3 Camera
