Avalon is gone now and 3 more weeks to the 1st delivery attempt of the E.Fric. :). I've decided to mount it on BB Planet - after chating here with few members, there will be an 200mmm circular adapter bolted to the Top tripod plate, with 6 x M6 countersunk - possibly large 2 inch build up aluminum plate between tripod and mount base. Counterweights - SS 316 or 303 - 150mm diameter - i have few quotes: 2 locals now: and from Rowan Astro , but i am not sure yet - i will have to decide soon. Power supply is 18V - 3 Amp. And a last thing: controller - working on StepOne and on Pulsar 2 .. Sitech won't work (not at the moment), StarGo - i didn't get very exited using it on the Avalon... it was working fine - once you get going (it might take a hr or two),.. Gemini software (from G11) - won't work,...
