Here is an image of M5 taken in early June. I have attached a mid size thumbnail. A full size image as well as exposure and processing details are at:

http://jthommes.com/Astro/m5.htm

Scope was my C8 at f/6 and the camera is the Artemis285. The focal reducer is the Celestron f/.63.

Exposure was 34 minutes 16:6:6:6 L:R:G:B.

Very nicely done. No core burnout and a lot of detail.

Greg.

Thanks guys for all the nice comments.

The processing on this image involved some masking of the core and selective processing to maximize detail from core to edge. So it is completely blown out for any type of photometric comparison. But I had fun with it.
