Hi All,
Yes, I have been tinkering again. Love retirement! Anyway, working with Ales over at Istar Optical, I came up with an adapter that will allow the owners of the Celestron C6R (w/adjustable cell) the option of upgrading to an Istar 150mm F/8 R35 lens or standard Istar 150mm F/8 achromat. Got a lens not performing well? This may be an option for you. This CNC machined adapter is a composite of ABS plastic and MDF so as to not add more weight to the front heavy C6R. The use of this mod only requires a change of in focus position of about 3/8" and installs in about minute. The lens cell adjustability is maintained. Send me a PM if interested in the adapter.
Hope to get some photos and do a lens comparison soon.
