Crescent Nebula Wide Field

Here is the same object in H-alpha, of the Crescent using the shorter focus Honders and the STL11K 9 micron pixel CCD camera. These are again 10 minute subs taken over 2 nights of fair seeing. 1.6 arc sec per pixel with an average star size of 1.95 arc sec FWHM, 30 x 600 seconds. On the bottom left you can see Dave Jurasevich's Soap Bubble nebula. On the top right we have what I call the Waterfall. Lots of other little snicks and sniggles.

Fantastic images, Roland! Are you planning to add SII and OIII to this one?
