Triplet Astrograph Telescope Askar APO 120 mm f/7.0

The latest addition from Askar to an already impressive line of telescopes, the 120mm triplet apochromatic refractor offers versatility and flexibility with the optional 1x Flattening Askar and 0.8x Reducer Askar.

Based on the modular design of the Askar telescopes, the 120 mm APO has a removable body extension that is necessary when using an optional binocular for visual use, making it a telescope of choice for a versatile imaging system.

Using ED glass, the Askar 120 mm triplet apochromatic refractor produces high-contrast images with pointed stars through a full-frame image sensor.

The 120 mm aperture of the Askar has a focal ratio of f/7 with a focal length of 840 mm. Add the 0.8x reducer and you get images at a focal length of 672 mm. Along with CNC-machined rings, a vixen-style dovetail bar, a slotted top rail for a guide telescope and guide camera, and a 10:1 dual-speed focuser.

The Askar 120mm APO is a fantastic choice for any astrophotographer looking for a premium refractor.

The Askar 120APO weighs 14.3 pounds when the rings and dovetails are attached - which means you can use it on almost all of the latest computerized equatorial mounts or even rugged alt/az mounts for visual use.

In addition to all these features, the modular body design of the Askar gives you the ability to use binocular scopes for visual use.

Packed with features, the Askar 120APO is a cut above the rest.
Fora true understanding of what makes this telescope a candidate for astrophotographers' dream refractor, take a look at the following list of the Askar 120's impressive features.


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 an air-spaced, triplet apochromatic design with an extra-low dispersion (ED) glass lens to limit chromatic aberration.


Quality from start to finish

The Askar 120APO includes everything we love about refractor design. The dual-speed, 10:1 ratio focuser allows precise focus control when using the scope visually or with an optional Bahtinov mask (sold separately).

The included handle on the CNC rings is designed to fit guide scopes, aiming scopes and other accessories that use a synta style aiming shoe. Askar has included two additional synta mounts on top of the focuser providing ample space to add all mountable accessories for a successful imaging rig.

The 290mm Vixen style dovetail is double mounted on CNC rings ensuring a stable connection to its equatorial mount and the adjustable dew shield prevents wasted hours under clear skies by protecting the ED optics from moisture.


Optical Versatility

In addition to excellent build quality, Askar has taken into account the need for versatility in an imaging refractor. Askar offers its Askar 1x Flattener for those who want to photograph nebulae and galaxies at the full 840mm focal length and maximize the resolution of their imaging system.

Next, Askar offers its Askar 0.8x Reducer, which transforms the f/7 refractor into a faster imaging system. This is a great combination of resolution and light gathering power, especially for cameras with small to medium pixel sizes (2.3um - 3.76um).
