Hey all you fine folks, last night I went out with a friend to a dark sky and shot some more deep space images. Shown here is the Andromeda Galaxy (M31) and the Pliades (M45) photographed with my D700 & NO NOISE REDUCTION WAS USED for these images. Both were single 7 minute exposures at ISO 400 and there is no noise at all...AWESOME! The scope used was a BORG Astrograph, a 4-inch ED refractor at a FL of 390mm f/4. I tracked the scope on my Celestron mount. Used the MC-36 remote timer for the 7min exp. The fact that the outside temp was aroung 40º kept the CMOS cold and thus keeping noise away. Enjoy...
