I have a meade DS80 I'm trying to use as a guide scope but I'm having trouble finding a star to guide on with the current setup. I went cheap and bought standard rings, not guide rings. I figure a reducer would broaden the FOV and speed up the scope for my crappy CCD guide camera.

I have replaced the heavy diagonal on the DS80 with an 80mm extension tube to achieve focus and it's all good, but I'd like to stick with a 2" reducer so I can use it with a dslr one day.

Can I screw it onto the telescope end of the extension tube or does it want to be closer to focus, ie: on the end of the 2" to 1.25" adapter? That would make getting eyepieces plugged in challenging to say the least.
