Refractor 80 mm

Availability: manufactured on request; Type: refractor

We manufactured only a small series of 7 pieces with F/6 focal ratio, based on a request from a friend of ours, Catalin Beldea. He wanted something portable & light, yet good enough optically to carry around the world for capturing images during total solar eclipses. It has proven to be a very good decision, the telescopes being sold very quickly after the initial launch. Highly portable and with its compact size, we recommend it for travelling, solar eclipses or birding/wild life observing & imaging. We still have some pieces of S-FPL53 on stock that could make a small series of 80mm F/6.9. These units will be manufactured on request.

Main features:
* 2" rack and pinion type focuser from Starlight Instruments;
* dew shield with rotate & lock feature;
* airline travel friendly, being very compact & light
* Oil-spaced design for best possible light transmission & highest contrast.
