Perhaps "digiscoping" with a good spotting scope is a better option?
I recently acquired an Opticron. I ordered a connection ring to use with a Panasonic LX5 from China, it arrived today but its the wrong one. Panasonic, for reasons known only to themselves, changed the thread pitch from the LX3 to the LX5 on the thread on the lens
I'm using M42 extension tubes and a deglassed 3x TC to make the connections, the scope has an M42 thread by the ep. The typical digiscoping technique seems to be to photograph the image produced by the scope ep with the camera lens, which is why small sensor cameras are used a lot. The exit pupil of the dedicated digiscoping ep seems to be around 10mm. I did try a few pics directly through the scope but the focussing range I was able to achieve was only 2-10m (and of course the image in the camera vf is inverted and up-side-down - very disorientating).
I'll post a few results as and when. _________________ pentax ME super (retired)
