Due to increased demand of our limited edition 132mm refractor, we have introduced another series, based on our original optical design.
Highly portable optical tube assembly, based on the same focal length as our 140 mm F/6.5, with a slightly slower focal ratio due to its smaller aperture.
We recommended it for visual astronomy and photographic use when used in pair with our dedicated Field Corrector.
Main features:
* 3.5" rack and pinion type focuser from Starlight Instruments;
* dew shield with rotate & lock feature;
* highly portable, medium size refractor;
* Oil-spaced design for best possible light transmission & highest contrast.
