Here is last year’s pic with the M13 taken with a 10″ Meade SCT. Exposure was 22 frames at 60 second. It was probably one of the best pictures I got from the Meade. Because of being able to guide with the 5″ Mak, I was able to get ten 300 second subs to stack (for a total of 50 minutes instead of just 22 minutes). Here is the result. The magnification of the second image is only about 60% of the older picture, but better focus and guiding give a much higher resolution end product. Funny how a 5″ […]
