FSQ-106 & Feldstein #6

[Benny L (Ben)]

Hi all,

I have picked up a feldstein #6 adapter for my new FSQ and hooked it up last night..

It seems that there is not enough back-focus to bring the stars into focus, I am wondering if there is some sort of spacer that needs to go between the adapter and the FSQ itself?

any tips or points in the right direction would be very much appreciated

Bump...<ouch, that hurt...>

Yes, you'll need a spacer. Call or email the guys a precise parts, they'll make one up for you. The BFD is different between the FSQ-106N and the New Q (FSQ 106ED). The FSQ 106EDX and FSQ 106EDXII have a similar BFD to the original ED, however keep in mind that Tak have introduced the old CAA on the later models (instead of the stupid "captain's wheel" instrument rotator on the original ED) so there are subtle BFD differences.
