Thank you very much Michael!
I've machined an adapter so I can use a polemaster CCD to align the unit to hopefully give me some great imaging when the sky clears. I've decided to start off with a 14mm ide angle lens (f 2.8 Rokinon) then prograss to a 50mm lens (very old Nikkor f1.4) and hopefully eventually to my Nikkor 80-200 f2.8ED and the ability to get around 180 second subs. I understand that will all depend on my accuracy setting the unit up.
I'm currently using a gear head tripod mount with minimal weight capacity (6Kg, the 25Kg gear head was way out of my financial capabilities) because it's easy to set my latitude while still staying level across the head. I had a heck of a job trying to do the same thing with my 25Kg ball head, I couldn't move it in one plain without it moving in every other plain as well.
I'm considering making an adjustable latitude wedge for the mount to keep it's 15Kg capacity which will bring my 80mm Megrez into the game, hopefully. It's the first model and pitched as a semi APO so it should be reasonable for the task.
Now all I need is 12mm aluminium plate and a stand for a milling machine which I have the steel for, I just have to get out and weld it up one day.
The sooner the better me thinks. If I wasn't so stupid and could remember how to TIG weld alloy, something I haven't done for 25 years I'd weld construct the thing, I may get to practising soon on some scrap. I was very good at it and have the equipment to do the welding. otherwise it will be screwed together.
