*** SOLD, thanks DW ***
I have a set of Milburn rings for sale. These are a very stable method to mount an ST80 to a C8. These run $119 new, my set is for sale for $85 (including CONUS shipping).
I purchased these thinking I would do some film astrophotography but I've never really had the time or the patience (I guess this is a common story here).
These rings are in good (not brand new) condition. There are a few light marks from the set screws visible on the top of the polished aluminum dovetail. The front ring is also very slightly out of square (it was this way as manufactured, I believe). The ID on these rings is 4.5".
I don't have a digital camera, so I've attached a picture that I grabbed from the Milburn website. The rings I am offering are the same as the smaller set, except instead of flat thumbscrews my unit has 1" diameter plastic thumbwheels.
Thanks for looking.
