Well, got the item I needed from Texas Nautical - Vixen style dovetail drilled for Tak tube ring. Probably should of thought all this through ahead of time. Now I have three separate packages arriving tomorrow - scope, tube ring, dovetail. At least I know it will be functional. I have two mounts, HEQ5 Pro and AZ GTI. Looking to perhaps switch out tripod on AZ GTI. I have a wooden tripod, quite nice and compact, but the head/top is an odd design. I think it is an old Russian TAL tripod. Very well built, I am just going to have to figure out how to get the AZ GTI head on the tripod. But I have two functional mounts for now so it not urgent.
