M13, the Great Globular Cluster in Hercules

M13 (& NGC 6207 far left).  My HAS image has been replaced by my Davis Mountains Image, which is a combination of 4x4=16 minutes exposure from 10/2007.  Canon EOS 20Da (unmodified), ISO , Takahashi TOA 130 (a 5" APO refractor) & flattener, and Astro-Physics AP 900GTO mountAPOD has more info on M13 here.

M92 above, 2x4 min, Davis Mtns 2007

Above is not reduced in size (full resolution of camera), and replaces HAS image.  M92 is a decent cluster in Hercules, but is understandably overshadowed by M13.   ~3 x 4 minute exposures at ISO 800.

All images:  Canon EOS 20Da (unmodified), Takahashi TOA 130 (a 5" APO refractor) with the TAK flattener, guided with  SBIG STV, Astro-Physics AP 900GTO mount  My current image processing workflow is here. 

I've moved some Southern Star Clusters to this page.

Lots of scopes...

At least 50 people attended the HAS BBQ & observing event on Saturday, June 9th at the Columbus site.  Skies were pretty good until the fog started rolling in sometime around 2:00.  My setup is on the near left.  This was the second field trip for my new Astro-Physics AP 900GTO mount and I spend a lot of time experimenting with guiding.
