I eventually progressed to a Nikon F601 and adapted it to a Tasco 17TR 80mm x 900 refractor and played with eyepiece projection with the standard .98" eyepieces though not what came with the scope, they were rubbish. I had a Tasco remote focuser for the unit but it got expensive as I had no access to a darkroom and had to send my film out for processing only to find several labs auto brightened my images. I eventually became friends with a fellow who owned his own lab, was a professional photographer and often loaned me Nikon lenses if I was going to the motorbike races. In return I built several perspex display cabinets for him.
It was still tricky getting good focus but I documented everything in a little note pad (the old type used with a pencil, lol).
I still have the Tasco but it has a lens cell from a Vixen 80mm refractor, baffles and an adapter which takes my Williams Optics DSG Synta focuser. I can't remember the last time I pulled the little Tasco out and used it though.
Martin what power Televue powermate was used for those images?
They are crisp!

Leo,
Wide field Moon shot , no Powermate , just T ring and adapter
Remainder of images 2 x Powermate , 2.5x Powermate , 4 x Powermate and 5x Powermate
The Powermate doesn’t make the image crisp, it just gives you adequate focal length and focal ratio to capture detail and resolution
A focal ratio of around f15 to f21 worked best over those nights. The 5 x zoom function on my DSLR also allows close to 1:1 pixel resolution.
The Stacking program and Post processing program makes them crisp. The individual frames on the lunar terrain images were quite blurry, stacking and sharpening 1500 frames ( lucky imaging ) provides the magic with a crisp image.
Cheers
Martin
