Dave, I am happy for you to use my EP's in the comparison test.
Some you already have so you might like to test my:
2" GS 30mm SV,
2" GS 2x Barlow
GS 9mm Plossl.
I will also make my 12" GS Dob available for the 12" f/5 test of the EP's.(after it is collimated to perfection). It has no Tracking method.
Glad to help out with the test! The results will be very helpful in determining what is better for my scope.
