New Scope CFF 105 F6 with .993 strehl!
I just received my CFF 105mm F6 APO oiled triplet with FPL55 glass.
It has a 3.2 inch Feathertouch rotating Focuser with microfocuser.
The most amazing part is the test report on the optics. .993 strehl! I have never heard of a strehl that high before in a scope. I am wondering if its in part a result of using the FPL55 glass which is the same performance as FPL53 but better polishing qualities.
The scope is super well made with flocked interior of the dewshield and a nice sliding and locking dewshield, pearly white paint and the scope comes with a handle, rings and dovetail plate plus a mounting point for the finder scope.
I got a field flattener designed to cover a 16803 sensor. I only now need an adapter from the flattener to the FLI cameras. Later I'll get a Starlight Feather touch focuser electronic focus unit.
It comes with a soft case. I used to have a TEC110 F5.6 fluorite and it had a TEC made lightweight focuser which was too light weight for FLI cams. I think this scope will surpass the TEC, time will tell. Its an alternative to FSQ scopes (I have had an FSQ106N and an FSQ106EDX111 both good but I wanted something different).
Photos later.
First light is likely to be using a full frame mirrorless if I can find some attaching adapters.
Very excited.
Greg.
