Description

O3 = 35 x 900 sec
Ha = 19 x 900 sec x 19
RGB = 5 x 600 sec each channel
I didn't capture as much RGB as I would have liked, so the drizzle process left some artifacts in the stars. I should have taken shorter RGB exposures to capture more subs in the same time. But I still prefer the RGB stars to the HOO stars. Just don't zoom in too closely!
