Clouds cleared around late evening and plugged the 350D in Spot ON.
Focuses beautifully about 10mm out and having to add a 50mm extension for the EP now, that also focuses great about mid rack out. So I can save my money and just grab another GSO to put on the 8".
The GSO mounting base can also be machined out to allow the focuser barrel OD to pass thru it and then be held by the existing grub screws. So have saved myself heaps of bux not having to buy an extra low profile focuser from Moonlite.
Incidently did you know that Jaycar sells some very neat little motors with gearboxes on the end. Be ideal for focuser motors with a small voltage reducer. They are 12 volts but will run as low as 3V.
