BRESSER AR-152S overview

  • 1Description

For advanced users who have a platform and want to add a large-aperture OTA option to their observational arsenal, Bresser offers their AR-152S Messier 6" f/5 Achro Refractor Telescope without a mount or tripod. This Messier optical tube assembly (OTA) can be used for imaging or viewing near and deep-sky objects such as the Moon & planets, galaxies & nebulae, and virtually anything in between. It features an achromatic lens system to virtually eliminate chromatic and spherical aberrations which translates to an immersive distortion-free viewing experience with true color rendition across the entire field of view - especially at the edges. The combination of aperture, aberration-free optics, anti-reflection optical coatings, and a fast f/5 focal ratio make this telescope ideally suited for astrophotography and astroimaging.

While there is no mount included, a mounting cradle-ring assembly is provided. It clamps over the optical tube and lets the user adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balancing, while avoiding interference with other equipment. A stainless steel Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle, and a 1/4"-20 stud on the top of the cradle ring assembly enables a camera to be piggybacked onto the scope for wide-field photography.

The scope is equipped with a 2" rack-and-pinion focuser for over-sized eyepieces and accessories, and comes with a 1.25" reducer adapter and a 1.25" 26mm super Plossl eyepiece that yields 29x power on the OTA. The adapter also has integrated T2 mounting threads to enable the use of a user-supplied DSLR-specific T2 ring for astrophotography through the scope.
