Description

I finally pulled out my second rig and started a multi-seasonal project. My widefield scope will be dedicated to taking mosaics for the near future.
The first I just started will comprise of 20 panels and cover an area between Cassiopeia and Cepheus. This does not mean I will hold back with showing some of the work done and so I present here the first 2 panels... Panel 8 (Bubble) has 65 subs and panel 13 has 72 subs

Revision: B

Title Reprocessed with GraXpert background extraction

Description I tried out this morning the new GraXpert Beta software and reprocessed the 2 panel mosaic. I think the AI does protect the faint nebulosity better then my eyes placing boxes in the DBE. However I also started to see some gradients after stretching which let me think I might have a problem with my darks...or???
