Alloy Tube and Rings
l've rolled the tube for my new 8" newt and fabricated new rings.
the tube is .8mm aluminium with a 10mm fold for rigidity at each end and then fitted the collars from the original skywatcher tube.
a set of baffles will be fitted in the next couple of days.
the rings are machined from 20mm aluminium plate and drilled to suit a modified Losmandy plate, holes in the side of the rings allow fitting another Losmandy plate which will hold a Stellavue 13 x 80 finder, this also allows the weight of the finder to go back over the mount and balance with a lot less counterweights.
