Images were taken with a Peltier Cooled Modified Canon Rebel XSi (450D). Ambient temperatures were in the range between 33 degrees to 42 degrees Fahrenheit. Temperature of the peltier cooled camera ranged between 5 degrees and 11 degrees Fahrenheit allowing for noise-free imaging with the DSLR.
Telescope used for imaging was an Astro Tech 127mm ED APO Triplet refractor using a Celestron f/6.3 focal reducer for Schmidt-Cassegrains. The Astro Tech 127 and ED80 refractor guide scope were mounted on an Orion Atlas EQ-G mount. The EQMOD ASCOM driver was used to drive the mount directly via an EQDIR interface module. Images are Full Frame.
