With the upgrading of electronic astronomical accessories, electronic devices are more and more widely used in astronomical observation and astrophotography. To better meet the needs of astronomy amateurs, we launched the FMA180 PRO AF Kit.
For the purpose of better catering to our customers’ practical needs, we again upgrade the ACL200 lens, introducing the ACL200 AF kit (AF refers to automatic focusing) to the market. ACL200 AF kit enables users to operate the lens together with ZWO’s EAF (electronic automatic focuser) to realize auto and more accurate focusing.
DSO imaging cannot live without long exposure, and long exposure cannot live without guiding. To reach more accurate guiding, Askar launches a new 32mm F4 Guide Scope. It is optimized in the structure, providing users with better imaging quality on the base of good guiding ability.
Askar Backfocus Adjuster M54(F) to M48(M) with variable 16mm-20mm extension
The M48 backfocus adjuster's front telescope interface is female thread M54x0.75 and the rear camera interface is male thread M48x0.75 (Please note that it is NOT M48 on both sides). The overall thickness is 18mm and it offers ± 2mm of adjustment range.
The backfocus adjuster is CNC machined. Each unit is a 0.05mm precision adjustment, and the surface is printed with a scale for easy adjustment and to save the position. There are two holes for fixing screws, which make the adjuster easy to use with different products.
By rotating the backfocus adjuster, it can be adjusted between ±2mm to match the backfocus requirement, and to solve the various imaging problems caused by the backfocus.

Users are often racked by the task of choosing and matching dazzling filters as well as adapters when it comes to using a filter drawer. It just becomes more confusing for those who are quite new to astrophotography. To solve this problem, Askar introduces a multifunctional filter drawer. The major feature or strength of this filter drawer is its integration of the most marketable filters, telescope and astronomy camera adapters. Users basically don’t need to worry about the related issues any more with this five-in-one filter installation device.
Askar 2" 90-deg 99% Dielectric Mirror Diagonal for Refractor or SCT Telescopes
To make the astronomical observation more comfortable, Askar has newly launched a 2” high precision diagonal.
The high-quality CNC machined diagonal, with its matte interior coating and gloss oxidized surface, brings a more premium texture and a more comfortable feel. The all-black colour gives you the impression of stability. The integrated, streamlined design of the diagonal makes it easy for users to carry and use
Askar’ s new-launched 65PHQ 0.75× full-frame reducer has a quadruplet design. The 0.75× reduction gives 65PHQ a shortened focal ratio of f/4.8 and a shortened focal length of 312mm. This reducer, connected with the astrograph, can effectively shorten the exposure time and dramatically increase your field of view, bringing more convenience and possibilities for your deep-sky astrophotography. The backfocus is the standard 55mm. It comes with two thread adapters of M54, M48 with a built-in M48×0.75 2” filter thread, so it is convenient for connection.
Askar provides a brand-new F3.9 full frame reducer for FRA400 astrograph, further reducing the focal length and thus shortening the exposure time on its original 400 focal length and f/5.6 focal ratio design basis. The reduction factor is 0.7×, and the reduced focal length is 280mm, which can satisfy most deep-sky astrophotography. The back focus is standard 55mm. The reducer has built-in M48×0.75 thread, easy for the attachment of 2" filters.
Note: This item may or may not have the 'Askar' brand imprinted on the item as pictured above. It just varies from batch to batch.

65PHQ is a flatfield astrograph newly launched after 80PHQ, 107PHQ, and 130PHQ. Instead of buying extra flatteners, calculating the back focus of the flattener, or making a tedious connection to match the correct distance, astrophotographers can simply equip it with any possible imaging accessories, make the target stay at the focus, and then the whole optical system is perfect for imaging.
65PHQ has a smaller size than other PHQ astrographs. 65PHQ has a focal ratio of f/6.4 and a focal length of 416mm. Instead of the quadruplet structure of other PHQs, the 65PHQ is a quintuplet with two ED glasses which offers excellent control of chromatic and other aberrations. With its self-flattening design, 65PHQ offers strong advantages in the astronomical shooting. It supports the full-frame image circle and has a fine spot diagram with tiny distortions of the peripheral stars.
The ZWO ADC actually does work well. It takes a bit of practice and some searches through the internet on how to use, but if planets are low in the sky the ADC will provide a better image.
