Description

Total intergation of almost 12hrs time on 8" Newtonian with a 2x Barlow collapsed into a meager 3,5hrs, as most subframes were to faint to properly stack in Pixinsight.
Twiddled with all Pixinsight setting I could find, but could not get it to process 100% of the images.  

Processing 2x Dualbanfilters to derive an artificial SHO image, which was the other learning curve to master.

Learning:
- turning an f/5 into an f/10 is a poor idea
- crisp subframes allow for better stacking
- processing every nights results alert earlier about a bad path to go - here I only notived after a fortnight of acquisition that I went down a dead end ...
- ots ok to give up processing of poor frames when they are poor :-)
