M33 (5in f6).jpg
M33 Galaxy, with 5-inch apo refractor at f/6, with Canon 20Da camera at ISO 400. Stack of four 16-minute exposures. Taken from home on Nov. 20, 2006 on a superb night, very transparent and no aurora at all. Near perfect night. Guidetstar was lost for fifth exposure -- wind blew dewcap in front of eFinder guider lens. And seeing bloated up a bit more for the 2 to 4th exposures.
