Early British AA Predictor Telescope
« on: August 12, 2019, 06:46:04 PM »
Smaller than the 1940 CTS version, no reticle and hence no need for reticle illumination, this smaller telescope give the same magnification but a slightly bigger FOV. It has a bigger ocular and smaller objective (25mm  as opposed to 50mm) and was probably intended for daylight use only.

These telescopes were sought after post war because of the high quality of the eyepieces and, sadly, few survived. The smaller ones were made in far smaller numbers - this is the first I've seen.

This film shows a predictor in use;
