NGC6990 - Eastern Veil HaLRGB
 
Location: Portland Downtown
 
Ha: 110 min.
Luminance: 60 min.
Red: 30min.
Green: 30min.
Blue: 30min.
 
I learned through doing my first HaLRGB that there is something like "too much Ha signal".  Even when I'm doing short exposures of 150 seconds, I learned that a mono CCD gathers 3-4x more than my previous DSLR.
 
 
Enjoy it!
