cookie8,
I think there's a lot to be said for sticking with prime focus as Merlin66 said.
I was of the same mindset as you, thinking that I need magnification.
The fact that the CCD sensor is so small means that you are resolving a very small proportion of the image.
I read somewhere that the small CCD sensor on pime focus gives you the same image as a 6mm eyepiece on the human photon receiver
.
I don't know if this is correct, but I find prime focus more than adquate to get started on lunar imaging. Get results with what you got before you buy more gear.
Seeing isn't very good tonight - that's why I'm in front of the computer and not outside with the scope.
