Just got my H alpha filter Monday and last night was clear so I gave it a spin from my light polluted backyard. I picked the worst target, looking south relatively low to start with. Just above my neighbourg's roof and his damn flood lights, over the M7 lights and finally coping with some major sky glow from cross roads on the hume Highway. I've got to say I was just stoked with the result considering, I wasn't expecting much. But now I'm considering getting SII, OIII and a shed with a roll of roof
Picture details: 20x10min. 2" Baader Ha 7nm + MPCC + Clear nose piece + QHY8 [gain:1 offset:60] + Newtonian Celestron 5" F/5 at prime focus + G11 autoguided with ED80/PHD. Didn't think I would need flats but I will next time. Did also a bit of sharpening in CCD stack.
I tried using the Ha as a Lum and combine it with previous R, G & B I got from Wiruna but it turned out with "funny" colors so I'll have to do some more reading about this. But I'm definitely converted to narrow band now. For backyard imaging that is.
Thanks for looking. Comments/Tips most welcome.
