[Found] Wanted: Crayford Focuser

[CoombellKid]

Thanks for the replies, I'm no longer looking

I'm after a Crayford focuser, one of the GSO types will do either the standard
or 1:10 variety. So if anyone has one or has upgraded their GSO to the 1:10
variety and have a the standard sitting in a box doing nothing. Let me know
what you want for it.

Either variety will do but it must have 1.25" adaptor.

regards,CS

I've got a spare JMI Reverse Crayford 2" Focuser, if your interested.

I have the 1 1/4 inch adapter as well.

Paul,

How much are you wanting for it?

what does the reverse bit mean?

regards,CS

In the reverse Crayford design, the drive-shaft pressure is applied to a bar which "pulls" the drawtube against its supporting bearings as apposed to directly "pushing" the drawtube as seen in the normal Crayford design. This design gives zero image shift and zero backlash.

I have a flat base and a curved base, backing plate and all the mounting hardware.

In very good condition and 6 years old.

The focuser would be $90AU posted. Payment Paypal.
