Description

haRGB image 
acquired over several nights in March 
nearly 10 hours of Ha data 
HDR combination of 30s and 10s subs 
about 20 hours total integration
ok image but not overwhelming considering the effort of stacking 100s of 10 second subs over rgb- have to keep working at it 
It's so dusty and windy this time of year in West Texas - doesn't mix well with my mirrors, which I just cleaned and already have a dust coating, and my long tube, that is like a sail some nights.  My phd graphs are horrible these days.
