Design and Build
The Unitron is a 60mm F15 (900mm) achromat. It’s a completely traditional configuration that can deliver excellent images with very little chromatic aberration. The lens is a classy-looking affair with a finely engraved lens ring and good coatings for the times. It looks vastly superior to the run of 60mm refractors. In practice, Unitron lenses were made in various small Japanese optical shops and quality isn’t what you might expect from its appearance.
The tube is long and enamelled in a brilliant white. At one end is a push-fit white dew-shield, at the other various handsome fittings accented in lustrous black. Did I mention it looks good? The tube comes with a pair of brackets to hold the rod for a solar projection screen and all such accessories on the Unitron are made from hard, brittle Bakelite. Mostly the Unitron is a high quality device, but those Bakelite fittings for the finder and sun screen holder tend to crack, old as they are.
The focuser is unusual - a long, push-fit drawtube and short-travel rack-and-pinion with the black Bakelite knob (matching the ones on the mount) on the right side only. The draw-tube provides coarse focusing, the r&p fine. It would be a good system but there is some flex in the drawtube and it can ‘sag’ when extended. I found greasing it sparingly tightened things up.
The tube fixes to the mount head via a little black clamshell secured by a couple of Bakelite knobs - no dovetails back then. The mount itself is the same black enamel as the clamshell and the tube fittings, whilst the mechanical bits appear to be stainless. The mount is small and very well engineered and sits on a set of long tripod legs made of what looks like boxwood. Slow motion controls – smooth and accurate – are provided for both axes.
It looks good … really good.
