Pat, below is an image of my Tak FSQ-106. The OAG has since been removed (want one? ), but the image train is 4" focuser to M72 to 2" compression ring (Tak makes them SO fine there is NO slop - you fight air pressure installing things!). CCD has a 2" nosepiece with an M48 UV/IR up front, and screwed onto my IDAS copy T2 filter, which then screws onto the CCD.
No flex apparent, but I am waiting on my Precise Parts threaded adapter to arrive to mitigate it all.
ah ok lewis, so my 3" ff/fr screws directly into my qhy ccd as it is no problem, the idas has only 1 threaded side so i can thread it to my ccd but then cannot attach the fr to that!?
cannot see how i am going to mate it all with only 1 threaded side?
pat
You will need a compression ring adapter or similar if you want to use a 2" nosepiece
The IDAS by memory has a female thread on the front that you can screw an adapter to - I do know Teleskop Express sell a 3" to M48 male adapter and a T2 adapter also (screws to front of an M48 or T2 filter)
), but the image train is 4" focuser to M72 to 2" compression ring (Tak makes them SO fine there is NO slop - you fight air pressure installing things!). CCD has a 2" nosepiece with an M48 UV/IR up front, and screwed onto my IDAS copy T2 filter, which then screws onto the CCD.
