StellaMira 90mm ED Triplet f6 Refractor Telescope

Product Description

Now includes a Losmandy-style dovetail mounting bar (photo shows earlier Vixen-type bar), and the rotator has engravings showing angular position. The StellaMira 90mm f/6 ED Triplet refractor is designed for the discerning astrophotographer or astronomer, so it has a minimum 0.95 Strehl ratio and includes a test report.

Fully multicoated triplet optics, with an ED lens equal to FPL-53, deliver high-contrast views with very low chromatic aberration. The sturdy 2.5" Rack & Pinion dual-speed focuser with 1:10 fine focusing and integral rotator, provides excellent load-bearing capacity and precise focus adjustments.

All StellaMira triplet telescopes are QC-checked in the UK to ensure they achieve their full potential.

CNC-machined aluminium fittings and Carbon Fibre tube provide high strength and excellent thermal properties.

The price includes CNC tube rings, a Losmandy-style dovetail mounting bar, a carry handle, and an aluminium carry case.
