Very interesting & informative thread. I came SO close to pulling the trigger on a K3 II last weekend, but decided it was just outside the budget for now, and the K3 with battery base thrown in for less money is awfully tempting. The astrotracer is what really appeals to me on the II though.
I just got a Celestron 130mm telescope for my birthday :-) and am going to be trying it for photos once I get over the initial thrill of just being able to see so much with it. I'm not sure if I'm going to go with a T mount & one of my cameras or get one of the celestron webcam type cameras that fit on it. I've never heard of these T mounts before but to me it just looks like an M42 adapter that screws into an adapter that fits where the telescopes eyepiece would go.. is this correct?
Last April I was getting some hand held shots of Venus when it was so bright, and decided to try a couple of Jupiter too with just the telephoto with my wifes Kx and my Nex-5N. I was pleasantly surprised when the Jovian moons were visible with just the lens, here is a shot I took with the Nex camera and 200mm lens on it. I don't know if it was lens flare or just jiggle, but the out of focus moons made them look a lot bigger than they are for kind of a cool effect.
