Globular Cluster, M68, Picture
The first 3 star cluster images are from March 2008 at the HAS site. I am now incorporating some quick star cluster shots into my astrophotography process. I shoot them early to check for good focus and good tracking confirmation.
A very nice cluster in Hydra, this image is just one exposure! Dreyer description : Globular cluster, large, extremely rich in stars, very compressed, irregularly round, well resolved, stars of magnitude 12; = M68.
M 48 is an open cluster in Hydra, Dreyer description : Cluster, very large, westward rich in stars, westward much compressed, stars of magnitude 9 to 13; = M48. A couple frames.
M 93 is an open star cluster near Puppis. Dreyer description : Cluster, large, westward rich in stars, little compressed, stars of magnitude 8 to 13; = M93. Maybe 4 frames. M67, from March 2008, is on this page.
...aka Owl Cluster, Dragonfly Cluster, Caldwell C13, Hershel H42-7... This lives in Cassiopeia, and is a popular object to show people new to astronomy as it does look like "ET" through the scope. 3x4 minute exposures at ISO 1600, Canon EOS 20Da (unmodified), Takahashi TOA 130 (a 5" APO refractor) with flattener, and Astro-Physics AP 900GTO mount. 12/29/2007 from Starry Nights in Wimberley, TX.
