How I connect my Canon EOS 350D to my Meade LX200:
The variable-t adapter gives me about 118mm spacing--maybe a tad much, but it's close. I may try removing the long t-adapter and moving the focal reducer to the front of the focuser. The spacing changing with the focus kinda weirds me out, though.
How I connect the MacBook to the telescope, camera and guide camera:
Man, that's a lot of stuff hanging off the back of the scope. I don't know how I'd want to shorten it up, though. Maybe invent a low-profile focuser where the drawtube actually extends up into the LX200 baffle?

Looks like someone stole my idea, sort of. Check out this focuser from Moonlight where the focal reducer attaches to the end of the drawtube. Very slick!

Here's another slick solution to the long overhang. He's moved the focal reducer to inside the focuser drawtube. Good stuff.
