What can I say Chuck? I stand in awe (but not for long, as I often need to sit)... 73 On 2/12/2013 12:51 PM, Chuck Hards wrote:
I'm nearly finished with an RFT refractor built around a (as sold and stated in their literature) Jaegers 110mm f/4.5 doublet. Using an original Jaegers lens cell, the clear aperture turns out to be nearly 107mm and the actual focal ratio is closer to f/4.4. It uses an Antares (same as GSO) single-speed 2" Crayford-style focuser. Aluminum tube and dewcap, Orion tube rings.
