Hi Folks;
Just finished the preliminary LRGB image of NGC 6946 - the FireWorks Galaxy:
http://www.outcastsoft.com/Prototype/NGC6946_20120820_MJA.jpg
Five 20 minute luma binned 1x1, three 5 minute red, three 5 minute Green and three 6 minute blue binned 2x2. AT8 RC 200 mm scope @ 1625 mm focal length. Grasshopper 2 camera cooled to +3°C.
Measured FWHM is 3.5 to 4.5 so it's a little softer than the other night. Sky background was around 4,500 (out of 65,535) at this dark site.
It's basically cloudy here today and the forecast is calling for showers after tuesday - so this may be all the images I capture.
TTYL..
