Russen-Refraktor 70mm ZRT-457M_01red.jpg

 

I am looking for information on my recent aquisition.

 

This russian made ZRT-457M 70/457mm achromat is in great condition and came complete with foldable table top tripod, manual and carry on bag. A solid feeling turn lever lets you select either 30x or 60x magnification. Dating back to the days of the cold war, manufacturer Kazan Optical built these in huge quantities for military use. After the cold war had ended it was adapted for use on shooting ranges. My unit is serial number 963509 and was built in December 1996.

 

Anyone own one of these?

First light today! Saw a couple of sunspots with my Baader filter. Even granules visible in moments of steady air. CanĀ“t wait to check this thing out on the nightsky.

Closeup of selector switch. 30x suffering from some loss of outer image sharpness. 60x sharp and contrasty to the edge.

Sun high in the sky. Quick hack, stacking chairs for comfy sunspot observations.
