California HA

Lovely night on Friday, so I bagged this from the back yard with the dual HA rig. 12 x 900s on the QHY 9 and 18 x 600s on the QHY163. 7nm Baader HA, Nikkor ED 180 lenses at f/3.6, hope you like it!

That's amazing! I really like the intricacies of gas on the centre top of the image. 

Thanks for sharing

Thats incredible.  Did you drizzle this data?  The fine Ha structures located in the faint wisps of the edges are all over the place.  Very awesome, great acquisition and processing.

Thank you very much for the kind words! No, I didn't drizzle - Linear Fit image integration was used at default settings in PI after calibration with the usual bias, darks and flats. The Nikkors are very fast at f/3.6 which really helps. The image is the result of 6 hours total exposure which was gained in 3 hours real time with the dual rig. ?
