Since I
blew up my QSI583ws, I was forced to use my 5DII at Astrofest. I decided to make use of the full frame, and coupled with the 135L lens instead of a telescope, go for some very wide field shots that I wouldn't normally attempt.
Here is Corona Australis - the whole constellation. Typically you see just the dust and reflection nebula around NGC6723 etc. I've always liked this constellation visually as it's very clear in the sky and easy to find.

Attached below are 800px and a crop of 6723 area.
Edit: Just added a reworked version to accentuate the dust and constellation shape stars
