This came with a 'scope a while back and I don't really need it. Since I don't have a controller I can't test it, but it appears to be unused so I will guarantee it against being DOA. If it doesn't work, you can return it to me and it will only cost you the return shipping.
Anacortes's web site has more info on this. New ones are selling for $55+ shipping This one has a $48 Anacortes price tag on it. It is the 6" version that I believe fits 6.5-8" OD tubes.
The package is clean (orange stuff in the picture is a reflection).
$35 shipped CONUS
