Question about 2" nosepiece
« on: September 13, 2017, 08:04:08 PM »
Sorry if this has been asked before, I actually couldn't find anything on the net...

I just took possession of a color infinity and would like to use a 2" TPO .5x focal reducer and possibly 2" filters down the road. I'm trying to stay away from 1.25" stuff to reduce the chance of vignetting.

How can I use 2" threaded items? Are the threads that the 1.25" supplied adaptor M48 x 0.75 (normal 2" scope threads? If so and I can thread the focal reduce right onto the camera, will I need tubes or a nosepiece to insert into the back of my refractor?

I'm kind of lost here and could use some advice :-)
