Askar 52mm F4.8 Super ED Guide Scope

The 52mm Super ED Guide Scope includes 1 piece of SD glass to achieve better color aberration control, to reach more accurate guiding and better imaging quality. At the same time, the 52mm SD Guide Scope provides users with more ways to use it.

The 52mm SD guide scope is light, compact, and stable. The aperture is 52mm, the focal length is 249mm, and the focal length is F/4.8. The focuser travel length is 25mm, and the weight is only 740g.

The aperture area of the 52mm SD guide scope is 164% larger than that of the 32mm guide scope, with the increase of light into， the limiting magnitude can reach 10.4.

The 52mm SD guide scope has a doublet objective lens design, including 1 piece of SD glass, providing more accurate guiding.

In addition to guiding, the 52mm SD guide scope can also be used for visual observation and astrophotography.

The 52mm SD guide scope comes with a 1.25” adapter, an M42 threaded adapter, and two 40mm extension tubes.

The extension tubes and adapter are removable to accommodate different usage needs.

When using the 52mm SD guide scope with cameras, the CMOS position relative to the focal plane varies depending on the type of camera attached. For precise guiding with a guiding camera, the rear 1.25” adapter can be attached directly. For planetary cameras or DSO cameras, the M42 threaded adapter can be used for attachment.

For visual observation, it can remove the extension tube and attach the 1.25” adapter to use the corresponding size diagonal and eyepiece.

The 52mm SD guide scope is designed with an XY-axis adjustable design, which allows to adjust the guide scope to be coaxial with the telescope, further enhancing the accuracy of the guiding.

To fully consider the user's feelings, the integrated Helical focusing design is adopted for smooth use, and the travel length is 25mm. Users can directly turn the focuser manually to adjust.

The 52mm SD guide scope base is suitable for universal finder slots and also has a 1/4 threaded hole and an M4 threaded hole on the base for easy attachment.

The 52mm SD guide scope is delicate and is crafted using high-quality CNC machining, with anodized treatment. Here are black and silver versions to choose from. The black one with a calm tone and the silver one looks more technical. The advanced manufacturing process gives them a textured feel, providing consumers with more options.

Nice, sharp and well built!

For a premium guide scope I was expecting a very sharp image and I was not disappointed. It is nice and crisp compared to other cheaper doublets.
I added a helical focuser and spacers on the camera end as I use a dew heater on the front end and want to be able to fine tune focus from the camera end. Not disappointed in this well built guide scope.

Super petit télescope intelligent

J’ai échangé mon S50 pour le nouveau S50 Pro et je suis très satisfait. De plus, l’application est régulièrement mise à jour pour offrir plus de possibilités et de facilité. J’adore l’utiliser pour empiler des photos d’astres lointaines pendant que je fais de l’observation visuelle avec mon SCT.

Très bon filtre pour photographier les nébuleuses

Je l’utilise avec mon Nexstar Évolution 9.25 et je suis très satisfait des résultats.

I had high hopes for it!

I had high hopes for the reducer as the FF131 scope natively was fabulous. It unfortunately has quite a bit of aberrations even using just a aps-c sensor. I even increased my backfocus distance on my adjustable BF adjuster to compensate for the elongated stars on the outer edges and it still had a hard time correcting the outer stars. It is something I will use if needed but not the majority of the time.

Hi Kevin_A, thanks for sharing your experience. We’re sorry the reducer hasn’t corrected the outer-edge stars as you’d hoped, even after adjusting backfocus. We will contact Askar about this situation and will contact you as soon as we receive an answer.
Thank you for your patience.
