Solutions is what it's all about. Yup, I can see how that would work.

This looks interesting.

I have an ST80 with 2" focuser (80mm F5). I'll check it out.

What's the max size this could be setup for, to do a full disc with a PST etalon well within the entire sweet spot?

Very best,

I used this method to mount the 110mm D-ERF inside the tube of the 150mm Celestron refractor that I modified.

As you say, works like a charm.
