Cassiopeia, with the 135mm telephoto lens, at f/2.5 for a stack of 6 x 2 minute exposures with the Canon 5D MkII at ISO 800. Plus star glows added with a layer of 2 x 2 minute exposures with the Kenko Softon filter. Field is similar to binoculars. Taken on a frosty night Feb 6, 2013, using the new iOptron SkyTracker tracking platform with the iOptron ballhead. It worked very well, though another 4 shots taken in the series were trailed slightly. 6 were fine.
