Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

I would prefer not to take the picture at face value. What the author failed to describe succinctly was whether the images were taken with the same sensor or its pixels has been binned to 2x2, 3x3 etc.
However, what he did decribed, threw me off balance.
When it comes to sensor imaging regardless CMOS or CCD, IMHO focal ratio still holds the rein when it comes to speed, all other factor equal.

Hmm.. I wonder where did you hear that? :roll:

Shh... I don't want to be blamed for any cloudy skies...
