Askar 80PHQ - 80 mm f/7.5 Flat-Field Super APO Quad Refractor - 80PHQ

The Askar 80PHQ  is an 80 mm f/7.5 refractor with high quality optics that will blow you away! The quad integrated optical design has three elements in the front and one in the back, which work together to produce high contrast, sharp images while reducing chromatic aberration and increasing imaging performance.

The Askar 80PHQ is nice and portable, with a length of 448 mm and a net weight of 3.9 kg. Because this scope has a relatively small footprint, it will work well with most any sturdy mount on the market. The included Vixen-style dovetail bar will, of course, slide into any mount with a Vixen saddle, but you can always use the 80PHQ on a heavy-duty equatorial mount with a larger saddle (Losmandy-style) with the addition of an accessory or two. Whether you are using this 80 mm refractor for imaging, visual astronomy or as a superb spotting scope or camera lens during the day, you will be impressed with it's build, design, and amazing optical quality!

The Askar 80PHQ comes with a big, sturdy 3" rack and pinion focuser with dual-speed controls and a 360-degree rotator. The rotator, or angle adjuster, is marked with an accurate scale, allowing you to adjust your perspective easily and repeatedly, if necessary.

Included in the 80PHQ package you will find a set of black Seiko cradle rings, a handle, a 300 mm Vixen-style dovetail to fit mounts with the same size saddle, a dust cover, and a set of four "stage shooting connecting tubes", as well an instruction manual.
