Gday everyone,
For sale I've got my Borg helical micro focuser.
In particular, the #7315 and #7316 elements.
#7315 is the non-rotating helical focuser itself
#7316 is the 1.25" adapter
More information on these 2 products on the official website here:

The focuser is threaded to attach directly to Sbig CCD cameras on one side and this page (
http://www.tellurian.ca/newastro/borghelicalpg.html ) reports it fits directly on Skywatchers' mak barrels. I have not tried this, so I can't confirm.
The way I have used the focuser is simple: place it into your normal focuser or diagonal, attach an eyepiece/webcam/... to it, bring the scope in focus with the regular focuser, fine tune the focuse precisely with the Borg micro focuser.
It's very light, well built, and it can be used with any scope!
A great accessory, really.
It's in mint condition as you can see from the pictures. The 2 elements come in their respective original boxes.
