A 160mm oil spaced triplet refractor for the connoisseur, hand made by Gyulai Pal in Hungary, with mechanics by Catalin Fus of CFF Telescopes, Romania. This is the larger brother to the 140mm version, with an impressive and imediately visible increase in light gathering and resolution.

The lens system is a 3-element oil spaced triplet with FPL-53 element, having an equivalent Abbe number to Flourite, and, despite the increase in aperture, the colour correction is still perfect in or out of focus and it meets our "Super APO" criteria.

Each of these telescopes is aspherised by hand for perfect colour correction. They are guaranteed to meet a minimum of 0.96 Strehl at a wavelength of 532nm. This is an iterative process and each lens can take weeks or days to perfect.

A dedicated large format field flattener is available, please enquire for specifications.

A CNC machined Altair Astro TMS 300mm Losmandy dovetail clamp is included.

An extremely tough custom made flight case is supplied.
