I know very little about its provenance apart from the fact it was said to have been manufactured in Cairns. It's carrying an easy 60+kg and doesn't blink. The axes are a good 32mm and maybe more (haven't measured yet). The drive is RA only with the usual nudge controls in both RA and Dec. The gears are a precision set of 359 teeth (perfect for siderial tracking) and as long as it is well aligned on it's pier, the lack of a dec drive is a minor issue at best. Besies, it's going to be a visual scope primarily so controlling a bit of drift is no biggie.
I'm hoping to throw a few Naglers at it on Saturday night. That'll be the test.
