Description

While I look at some orthognality issues with the 383L+ I thought I would give my new Atik 460 mono its first light as well as my first go at LRGB imaging (historically only NB, mono or OSC camera for broadband).

It was also the first time I managed to capture all the image filters and flats all in one night, which was a nice surprise.

Details are:

FSQ106ED @f/5 with Atik 460 EX mono, Loadstar/OAG. Captured in Maxim DL5 and processed in PS3CSE. Calibrated with bias and flats, no darks (not dithered).

L:80 mins Red:30mins G:25 minutes B:30minutes all in 5 minutes subs and all bin x 1. Total 2 hours 45 minutes.

I know it was a little ambitious try to fit M31 on a 460 chip but at least most of it is there.
