ZWO 86mm Holder Ring / Bracket for ZWO ASI PRO CAMERAS
ZWO Holder Ring for ZWO ASI PRO COOLED CAMERAS with appr 86mm diameter.
Currently compatible with the following ZWO cameras: ASI094, ASI128 and ASI071
Width of the base: appr. 33.9mm (widest part of the dovetail part)
It means this is not a Vixen-style dovetail, so it won't necessarily work with all Vixen-style dovetail clamps.
It looks like the manufacturer attached a dovetail bar that is used by several manufacturers of photographic ball heads and video heads. For example it fits our range of Kenro dual action ball heads.
Otherwise there is a 1/4" photo thread at the base of the dovetail bar and another 1/4" photo thread at the top of the tube ring. This gives several options for mounting to Sky-Trackers such as the Star Adventurer.
