Hi Gama,
If the sensitivity of the colour version is half that of the mono version, would you consider that enough to sway towards the mono camera?
I would still love to be able to use the colour version though, so I can use it for planetary imagaing as well, but not if it will cause too much of a loss of guiding accuracy.
I use a Canon eos 400d camera to photograph in prime focus through a 5" Schmidt cassegrain scope with a focal length of 1250mm.
The guidescope I will be using is a 70mm refractor with a focal length of 500mm.
My mount is a HEQ5 Pro.
At the moment i am using a cheap 640 x 480 webcam which i have removed the lens from, for guiding, but this only picks up bright stars, and even then they are very blocky, so I really have nothing to compare against.
Regards,
Wade.
