Confused About Astrophoto Equipment

Hi everybody!

My questions are about astrophotography, mainly in relation to the equipment. I'm planning on buying an 8" LX10 and obviously the off-axis guider is a must-have if you're planning to do any astrphpoto work. But doesn't that limit you to prime focus photography? I wanted to do eyepiece projection phtots as well, but from what I understand from the Meade catalog you can't hook the variable tele-extender or the variable projection camera adapter to the off-axis guider. And the T-Mount? I have a T-Ring for my Cannon. I thought the threads on T-Rings were standard and I could just screw it directly onto the off-axis guider.

On another point: Don't minor guideing corrections show up on the film later? Don't you have to close the shutter to make corrections?

Thanks! Luis Esetevs
