A lower cost option is the Televue reducer for the 102 F8 scope ( as I remember model 4087). This one costs less and is spaced at 55mm for DSLR cameras.

Here is an older picture shot with this combination:
Other than that I use a TMB flattner originally designed for the WO FLT-110 that works well with a specially made adapter. But it does not decrease the focal length. I use it since it was cheaper used than the original flattner from Tak. Here a result with the WO/TMB flattener: http://aida.astroinf...ge.php?pid=4750
Hopefully you can find a reducer on the used market, the new parts are really expensive...
