Askar 52mm F4 guide scope released

A guide scope is an essential tool for astrophotography (unless you are doing OAG), it helps to keep the main telescope accurately aligned during long exposures by correcting tracking errors. The Askar 52mm Guide Scope is perfect for this purpose. With its lightweight, compact design, it offers a 52mm aperture, 208mm focal length, and a 25mm travel length, all at just 631g (1.39 lbs). Its doublet objective lens and precise X&Y-axis fine adjustments ensure high accuracy and stability, making it a reliable and versatile choice for capturing the night sky.

Introducing the Askar 52mm F4 guide scope

The aperture area of the Askar 52mm F4 guide scope is 164% larger than that of the 32mm F4 guide scope, allowing more light to enter and reaching a limiting magnitude of 10.4.

Besides guiding, the 52mm F4 guide scope can also be used for visual.

It features a Helical focusing design for smooth operation, which is also handy becuase helical focusers do not change the rotation of the object, one of the things I have come to love. Users can manually turn the focuser to adjust it and the focuser includes an M3 locking screw hole for added convenience. The 52mm F4 Guide Scope comes with a 1.25” adapter and an M42 threaded adapter, meeting users' needs for connecting their imaging equipment, and since most guide cameras like the infamous ZWO 172 or th eZWO 120 are 1.25" - it's a great match.

Askar 52mm F4 scope details

The 52mm F4 guide scope has a standard Vixen style base built in, and also includes a 1/4 threaded hole and an M4 threaded hole on the base for easy attachment.

Its design reflects quality and value - which is something Askar is becoming known for. The accessories are refined, and the coating has a uniform texture. Available in black and silver, the black version maintains a calm tone, while the silver version has a metallic finish that appears more technical. The advanced manufacturing process gives both versions a textured feel, providing consumers with more options.
