Askar Black 52mm Super ED Guide Scope SD Glass for High Accuracy Visual Observation and Astrophotography
Description:
- 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.

- 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.
