NGC 6946 - Fireworks Galaxy

[Taman]

This beautiful spiral galaxy is in the constellation of Cepheus, about 22 million light years away. I was hoping to get more exposure time, but it clouded over around midnight last night.

18 x 300s with darks, flats and dark flats. Total 90 minutes.

Taken with the C11 at 1700mm, ASI294MC-Pro (gain 126, temp -12C) and Optolong L-Pro filter.

Stacked with DSS, calibrated and stretched in SiriL, star mask created with Starnet++ and final processing in Photoshop CS6.

It is a lovely object, well done. Must get on to it soon myself.

Thanks MarkAR! This is a first for me. I'd like to get more exposure time on it as I think it extends out much further.

Yes there are some feint outer bit just showing, more data will help.

Thanks Chris! I had fun imaging this until the clouds rolled in!
