Here's a nice example of Unitron's AZ mount.
I believe this mount was supplied with their 3" refractors. Both slo-mo's are smooth. Paint is blemish free and all stainless steel brightwork is, well, still bright.
These Unitron mounts can carry enormouse loads from a strict build quality, but they are limited on their weight range by the fact that their top-of-mount OTA location presents large imbalances once moving away from the horizontal.
On their larger scopes, Unitron acknowledged this and started offering counterweight systems on their heavier AZ mounts.
I sort of copied their approach, and this sale includes a conterweight shaft and CWs totaling about 3.5lbs.If you have a Unitron OTA you want to mount on this, the the CW set in question screws on in place of one of the OTA hold-down wingnuts. The conical nut used is tapped 1/4-20 and the CWs are mix and match stackable across 2 times 3 weights each.
So this sale includes the mount, the CW system. There is an adpater plate plate fitted to the bottom of the tripod hub that is tapped for M10 - making it compatible with most import tripods. No changes were made to the mount, and it can be removed easily.
The tripod adapter hub shown attached to the base plate is not included in this sale.
Price includes shipping within N.A. Elsewhere at cost.
