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. Below: M13
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 My HAS image has been replaced by my Davis Mountains Image, which is a combination of 4x4=16 minutes exposure from 10/2007.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 mount. APOD has more info on M13 here.
M19 is a globular cluster East of Scorpius
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. More Globular Clusters are below. They all are ~3 x 4 minute exposures at ISO 800.
M69A globular cluster in Sagittarius
M92A nice globular cluster in Hercules, overshadowed by its neighbor M13.
Telescopes set up on the outer ring at the HAS site near Columbus, TX.Dana Lindstrom took this image of my setup
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.
