M13 by S Migol, on Flickr

Here's my effort:

Scope: Orion 127 Maksutov Cassegrain (1540mm fl at F12.1)
Camera: Full spectrum modified Pentax K10D with peltier cooler
Mount: Losmandy GM8 with Gemini 2 and OPW upgrade
Tracking: Orion SSAG on ST80 with Maxim DL

Data: 77 lights of 10 minutes at 400 ISO, 44 temperature matched darks, 15 flats. June 19 to June 28 2012 in Menlo Park, CA.
Processing: DSS 3.3.3 beta 47, PixInsight DBE, ACDNR, masked stretch, curves, and histogram stretches. Exported to LR for final touches and upload.

This target was the subject of an exercise in improving tracking methods prior to a big star party. I wanted to collect data at a high resolution that would show errors clearly so that I could develop better techniques.

Congratulations, Mike - I'm quite honored to have been able to tie your image. Your M13 is quite superb. (I guess we'll see each other in the runoff!)

@Bruno - I thought your image was great, too. I'm not at all surprised you received as many votes as you did.

@everyone else - It was great to see so many images entered this month. There sure were a lot of very impressive photos.
