Hi All,
Weather has been pretty horrible of late for imaging but here is a short (6hour) narrowband run on Eta Carinae and some surrounding nebula.
I am pretty happy with the end result considering the 0.44" image scale, high level thin cloud continually within field, 99% full moon, and relatively short integration time.
Eta is fairly blown out but I guess you get that with ~25k/e well depth and 1800 second subs.
Hopefully Autumn brings some clearer weather.
Image details:
Telescope: CDK 12.5 @f/8
Camera: SBIG STT-8300
Composition: Ha/Oiii(Ha)/Oiii, 6x 30min subs @ bin 1x1 per channel, all subs are sky limited (just).
