About this product
Model: askar_130phq
Part Number: 130PHQ
Optical Bench Test
At FLO, we check all our Askar telescopes on an optical bench before dispatch.
So you can be confident your telescope will 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!
New, larger version of the highly successful 107PHQ telescope.
An excellent telescope for imaging small to medium-sized deep-sky targets.
The Askar 130PHQ telescope features a 4-element, f/7.7 optical design (triplet + integrated field flattener) with two ED glass lenses for outstanding colour correction.
The integrated flattener provides a 60mm imaging circle, making the 130PHQ suitable for use with full-format sensors. No additional field flattener is necessary.
For the ultra-high resolution, full format sensors found in modern astronomy cameras, like the ZWO ASI-6200, an optional 0.7x Reducer (reduces focal length to 700mm focal ratio to F5.4) is available that provides even smaller spot sizes off-axis.
The sturdy 3.4" Dual Speed Rack and Pinion focuser is fully rotatable and capable of handling loads up to 8kg. A visual adaptor is also included, enabling 2" and 1.25" accessories.
With the visual adapter removed, the focuser tube terminates with an M86x1 thread. The telescope includes four stackable adapters for direct attachment of a wide variety of cameras with standard metric threads.
The scope has a premium fit and finish and includes a set of tube rings, a Vixen-style dovetail and a carry handle with mounting holes for additional accessories.
A standard Finderscope adaptor, compatible with many Finderscopes and Finder/Guidescopes, and a foam-filled metal carry case are also included.
