First attempt at solar imaging

Just in time for the Venus transit, I got a Lunt LS60Ha (B1200) solar scope.  That’s a mouthful, but that means it’s a 60 mm objective H-alpha scope with a 12 mm blocking filter.  And after speaking with the fine folks at Point Grey Imaging at NEAIC last month, I bought one of their Chameleon cameras to go with it.  Put the two together, and you’ve got a great combination for solar imaging.

This image is my first full disk solar capture, and only my second time out with the scope.  Both the telescope and the camera couldn’t be easier to use, though I’m not used to worrying about getting sunburned while imaging.  I think I’m going to enjoy this solar imaging thing!
