20" Mirror Test - part 1 deep sky

The mirrors on my club's 20" have just been resilvered, and recollimated. I had to test it out, but my camera's adapter was too long, so I improvised and just tied and strapped my camera on. This is NGC 6781, an 11.8 magnitude planetary nebula in Aquila the Eagle. It looked great... pretty bright for something that magnitude and all of 1.8 arc minutes across. This was 11 x 30 second exposures.
