ASKAR 107PHQ REFRACTOR TELESCOPE
All Sharpstar/Askar refractors are subjected to comprehensive physical, mechanical, and optical quality control checks at the factory. Each telescope includes an official inspection checklist from the manufacturer.
We may partially open the telescope box to confirm factory certification, but we do not conduct a second inspection ourselves. However, if you would like us to perform a cosmetic and mechanical check before shipping, please indicate this in the comments when placing your order. We’re happy to do this at no extra charge—please note, it may delay shipping by 1–2 business days. Optical testing is not available.

Product Details:
The Askar 107PHQ is a high-quality 107mm f/7 apochromatic refractor built with a four-element optical system designed for exceptional imaging and visual performance. Its air-spaced triplet lens includes two ED elements to reduce chromatic aberration, while a built-in field flattener corrects for field curvature across a 44mm image circle. This integrated design eliminates the need for an external flattener, simplifying compatibility with many cameras and accessories.
At the heart of the 107PHQ is a precision 3.4" dual-speed rack-and-pinion focuser with a 1:10 fine adjustment knob. It supports payloads up to 8kg and can rotate a full 360°, allowing flexible camera orientation. The focuser includes a 2" and 1.25" adapter for visual use and terminates with an M86x1 thread for imaging. Also included are a series of stackable adapters to support M86, M68, M54, and M48 thread connections.
With its sleek green accents, the OTA is both attractive and functional. It comes with tube rings, a 300mm Vixen-style dovetail, and a carry handle that doubles as a mount for accessories. The optical tube measures 655mm long with the dew shield retracted, has a 138mm diameter, and weighs just 6.9kg.
Its 749mm focal length makes it ideal for wide-field astrophotography, while its sharp, color-free optics make it an excellent visual telescope too. When paired with a 35mm, 68° eyepiece, it provides a wide 3° field of view at 21x magnification—perfect for exploring star fields and nebulae. High-power views of the Moon and planets are crisp and free of false color.
The 107PHQ delivers exceptional value in a premium imaging refractor. For its price, this scope rivals others that cost significantly more, especially when used with APS-C and smaller sensors. Full-frame sensors may show minor edge distortion, particularly if a focal reducer is used.
Each scope ships in a custom foam-padded aluminum case for safe transport and storage.
