Telescope-Refracting Telescopes-Askar 120APO Triplet Air-Spaced Refractor

Let’s Talk Optics
With an aperture of 120 mm and a focal length of 840 mm, the Askar 120APO has a focal ratio of f/7. The optics are configured in a triplet, air-spaced, apochromatic design, with one lens made of extra-low dispersion (ED) glass to limit chromatic aberration.

Quality Through and Through
The Askar 120APO includes everything we love about refractor design. The Dual speed 10:1 ratio focuser allows for precise focus control when using the scope visually or with an optional bahtinov mask (sold separately). The included handle atop the CNC rings is designed to fit guide scopes, finder scopes, and other accessories utilizing a synta style finder shoe. Askar has included two additional synta brackets atop the large 3.3″ rack & pinion dual speed focuser, providing ample room to add all mountable accessories for a successful imaging rig. Askar includes a 2″ and 1.25″ adapter for using diagonals, eyepieces, and other 2″ or 1.25″ barreled accessories. The 290 mm Vixen-style dovetail is double-mounted to the CNC rings ensuring a stable connection to your equatorial mount and the adjustable dew shield prevents hours lost under clear skies by shielding the ED optics from settling moisture.

Optical Versatility
On top of Askar’s mindful build quality, they have certainly considered the need for versatility in an imaging refactor. Askar offers their Askar 1x Flattener for those who want to photograph nebulae and galaxies at the full 840 mm focal length while maximizing resolution from their imaging system. Next, Askar offers their Askar 0.8x Reducer, transforming the f/7 refractor into a faster imaging system. This is a great combination of resolution and light gathering power, especially for the cameras with smaller to medium sized pixels (2.3um – 3.76um).
