Vixen dual speed focuser retrofit

[LewisM]

I have a NEW, never fitted Vixen dual speed retrofit focus knob unit for sale. Has all hardware, instructions etc.

Will fit all Vixen with the newer pinion that secures the knobs with grub screws at side. Will NOT fit older tapered pinions - though I can supply a drop in pinion replacement for $20 extra.

Specs/details: http://myastroshop.com.au/products/details.asp?id=MAS-051H

My price for the unit is $200 posted, or $220 with the spare pinion.

SALE PENDING (sorry Chris, to another gentleman)

I'll check the specs and see if this fits my ED 103 swt,and check to see if the weight of the 40D will cause any issues.

Thought last time I asked Steve about these,the dual speed focuser was around $185.Maybe this is a more elite version?

Chris,

Yep, fits the ED103 - see picture screen cap:

For any of the "not fit" list, I have a drop-in Vixen original pinion ($20). No alteration etc required except unscrewing the pressure plate removing the old pinion, installing the new.

Basically if the scope has the "conical" knobs (aluminium or plastic), this fits. If it has the cylindrical "coin shape" knobs (usually plastic only), you need my spare pinion too.

Here is the same type of dual speed unit installed onto my Vixen FL102S (with a replacement pinion installed too). Note I added it to the LEFT side (you can put it on either), as I prefer to fine focus with my left hand for some reason.
