The Altair Astro 130mm F7 ED Triplet APO refractor uses a 905mm focal length lens cell with Japanese FPL51 ED glass from Ohara which is cpecifically chosen to be free of internal stresses and striae which affect optical quality in large size refractors. This telescope is not like other telescopes using the similar or the same mechanics and has rapidily gained a reputation for performance above the norm especially with visual observers. This is due to a special modification process at the final stages of production, cluminating in the production of a laser interferogram image which is delivered with every telescope.
NEW 2014 Version with a light weight dual speed "Rack 'n Pinion" focuser, Teflon-tipped adjustable rotator, CNC machined internal knife edge baffles, and a self centering 2" adapter. Both 1.0x and 0.79x 3" flatteners and reducers can be attached directly by unscrewing the rear self centering assembly.
