Crayford focuser with f/6.3 celestron focal reducer??

[imichelena]

Hi guys,

I have a Celestrion SCT 8" with the celestron f/6.3 focal reducer which has given me excellent results so far.

Now I am struggling with focus and I'd like to upgrade my standard knob. I've been looking at Crayford focusers but I am not sure about how will the setup be if I want to keep my focal reducer.

I've found the moonlite crayford focusers which allows you to have your focal reducer screwed into your drawtube but they have 3.25" thread while my OTA has a 2". 

I've found this one for my OTA:

But seams not to have the same option to place my focal reducer inside.

Any ideas or advise on this issue?

Thanks for the help!

Cheers.

Meade do this adapter that screws onto the focal reducer and fits in a 2" focuser, Meade and Celestron  focal reducers are basically the same, don't know if Celestron do anything similar.

Thanks for the tip dave! but unfortunately I need a 3.25" thread on my OTA to screew a 2" focuser. Unless there is an affordable focuser that has 2" at both ends (which I cannot find).

I occasionally use a precision BORG helical focusser for SCT.  That has a 2'' thread to go onto the SCT (or reducer) and a 2" adaptor at the other end (plus other adaptors).
