Carinae section in H alpha QHY8

First try at using H alpha, 13nm Astronomic, through the 12 inch newt...and my new QHY8
i know everyone puts them up as a mono , but i actually like it more with a red tint to it. bit over an hour of total exposure. Shot under a FULL moon, in cold and very damp conditions.
When the moon is not quite so bright will try other targets.... they are a bit hard to find manually when its so bright.

the blurry bit at lower right is frosting on the chip.... i opened it in the observatory to clean off the dust motes ( not while chip was cooled), but it appears the air was damp enough to cause a problem, will assemble it in a warmer location next time. No flats or darks applied because of this.... still pleased with the result.
