If anyone has an older style or new style Vixen focuser assembly they have taken off and no longer want, please let me know. I bought a VC200L, and it has a little damage on the rack teeth. I have filed them, and improved it a LOT, but still a little "lumpy" at one spot.
Doesn't matter what vintage, as the ratio is the same regardless. Or even if you just have a spare pinion and rack (they unscrew)
Contact Steve at http://www.myastroshop.com.au/ and order a new rack for your focuser. It wasn't much. I crunched mine a bit when my motorized focuser didn't want to stop one night. I got a replacement from Steve. All is good now.
