About this product

Model:  askar_107phq
Part Number:  Askar 107PHQ

Optical Bench Test

All Askar telescopes are tested in the UK on an optical bench. 

This ensures 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!

Introducing the new Askar 107PHQ F7 Flat Field APO Refractor.

The Askar 107PHQ is a medium focal ratio Flat Field APO Refractor features a 4-element optical design for sharp, false colour and aberration free images.

The focal length of 749mm is ideal for imaging medium to large sized targets with large sensors and achieving excellent resolution with a decent resolution per pixel when used with most modern sensors. It also ensures the 107PHQ works very well visually, ensuring this instrument is truly a dual purpose telescope. The 107PHQ can be used at high power for lunar and planetary observing and, equipped with a suitable long focal length eyepiece, for outstanding views of the milky way and other deep sky targets.

The built in field flattener ensures a 44mm imaging circle, rendering the 107PHQ suitable for use with full format sensors. No additional field flattener is necessary, which ensures the 107PHQ is easy to use with a wide variety of cameras and imaging accessories. An optional focal reducer will be available later this year - high resolution full frame sensors may reveal slight aberrations at the field edge particularly when used with the reducer.

The air spaced triplet objective lens includes two ED elements for outstanding colour correction.

Featuring a high quality 3.4" Dual Speed Rack and Pinion focuser that is fully rotatable and capable of handling loads up to 8kg. A visual adaptor is also included permitting the use of 2" and 1.25" accessories. 

With the visual adapter removed, the focuser tube terminates with an M86x1 thread. The scope also includes four stackable adapters for direct attachment of a wide variety of cameras with standard metric threads.

Also included is a standard Finderscope adaptor permitting the use of many Finderscopes and Finder/Guidescopes, and a foam filled metal carry case.

The scope features a high standard fit and finish and also included are a set of tube rings, a Vixen style dovetail and a carry handle that includes mounting holes for additional accessories.

The 107PHQ gives excellent overall performance and is a fine choice for anyone wanting a versatile high quality astrograph, ideal for use with APS-C and Full Format sensors and a superb visual instrument.
