I'am a complete new boy on the block but determined to experiment to make better use of the small amount of kit I possess.
I own a Zeiss Telemator which I recently acquired which belonged to Ray Wilson (the person who was in charge of astronomical telescope design at carl Zeiss Oberkochen for over twelve years. Needless to say the instrument is in perfect working order and in immaculate condition.
I have tried my hand at prime focus photography and recorded really good images of the moon on my Exakta VX1000 35 mm SLR (Ilford 400 ASA B&W film).
I now want to try my luck with eyepiece projection photography.
I have a number of 0.965" Zeiss Jena Ortho eyepieces (10, 16 and 25 ), various M44 extension tubes and the the usual conical eyepiece holder (0.965"/ M44 male thread).
After some research, i have concluded that nothing really exists out on the market (new or secondhand) which would allow me to provide a secure connection between my Exakta and the main scope tube incorporating a suitable eyepiece holder. I have therefore decided to press ahead and design my own custom made adapter and arrange for its manufacture in the U.K. .where I live.
My design is based on the premise of taking the front face of the eyepiece as close as possible to the swing mirror of my SLR, thus ensuring the capture of the maximum image available from within the eyepiece relief distance. This small adapter is essentially going to be very similar to the readily available conical adapter ( my name for it) which connects the 0.965" eyepiece to the main scope . The big difference being that in addition to the M44x1 male thread (scope end), the adapter will have a M44x1 female thread (camera end). The adapter i'am creating will act as an ordinary M44 extension tube but with the capability of holding a 0.965" eyepiece within. Different eyepiece powers (F.L's) can be accommodated to best position by extension tube adjustments as necessary.
Am I going down the right path here.
All comments would be greatly appreciated,
The adapter will be made out of 316 Stainless steel.
