Part Number:  S650G-A

Es Reid Optical Bench Test

All StellaMira Triplet Telescopes are tested in the UK by Es Reid on an optical bench. 

Es Reid is highly regarded in the optical industry so you can be confident your telescope will, from the outset, have well figured optics, negligible false colour and spherical aberration, and no astigmatism (the bane of any optical system!). Star shapes will be round, not triangular, oval or egg-shaped!

NEW! Premium quality 104mm f/6.25 ED2 Triplet Refractor with 'two' ED glass elements. 

Every StellaMira triplet telescope is QC checked in the UK to ensure it achieves its full potential. 

This premium quality apochromatic telescope has been designed for the most demanding astrophotographers and astronomers. 

To reduce chromatic aberration to an absolute minimum StellaMira ED2 triplet telescopes feature two Japanese Ohara ED glass elements (FPL53 & FPL51) together with a third element from Lanthanum. 

The sturdy 2.7" Rack & Pinion hybrid drive, dual speed focuser with 1:10 fine focusing and built in rotators (fore & aft) is capable of carrying at least 8kg. 

To maximise the telescopes high performance a dedicated non-reducing Field Flattener is available that provides a flat evenly illuminated field. 

Price includes CNC tube-rings, 13" Losmandy-style dovetail mounting bar, Astro Essentials M74 to M48 adapter, carry handle and aluminium carry case.
