Description

C49/Rosette Nebula. I dabbled in generating HOO out of OSC image taken without any filter in Bortel 2 sky (Death Valley). 

Some stars have a very strange halos perhaps because the focus was messed up in some sub-frames(?).  Temperature-dependent automatic focusing with EAF may not have worked as it should.
