Sharpless 274 Annotated - a photo on Flickriver

            Sh2 274 Medusa Nebula as seen in the backyard over a week of testing.  

New camera: QSI 683 WSG-8 with astrodon LRGB filters.

The RGB comes from 7 Blue, 9 Green, and 9 Red subs at 600 second durations. 
The Luminance is from 15 subs also at 600 seconds.

Calibration and stacking and combining done in PI.  Used Harry's videos to understand using Linear Fit to match density for Lum and RGB.

For work in the backyard, I'm rather happy with how it looks at the moment.  I'd like to try this with narrowband someday.  At this point, I think that the target helped show a starting path for getting good data.

The annotated version shows a lot of galaxies in the background.  Fun!
