Description

I've been revisiting targets now that I have a nice mono camera for my EdgeHD 11. This time, a more detailed shot of the Crescent nebula than I was able to do previously with my 102mm refractor. The HOO version is quite nice, and I see why most image in this pallet for this particular object as the OIII really shows up nicely. In SHO, it can barely be seen, and I'm not sure SII adds much to the image.
