Telescope-Reflecting Telescopes-Apertura CarbonStar 6″ Ritchey-Chretien Telescope

Premium Optics
This Apertura RC telescope has 6″ of aperture and a focal ratio of f/9, providing a 1377mm focal length. The 6″ Ritchey-Chretien’s primary and secondary mirrors have been upgraded from BK7 glass to quartz, which gives improved optical performance as the mirrors cool. Quartz has a coefficient of thermal expansion many times lower than BK7 which helps the optics to hold their precision-manufactured shape far better than other substrates. These changes further add to the already amazing performance of this little powerhouse of a telescope!

Linear Bearing, EAF-Ready, Focuser
Providing solid, smooth, focus travel for even the stoutest imaging trains is a linear bearing focuser. While similar to the Crayford-style focuser in appearance, linear focusers utilize many small ball bearings instead of a few bearing surfaces. This provides more points of contact, resulting in a strong yet incredibly smooth focuser. To make connecting modern imaging equipment simple, this focuser features M56 threading that can be adapted to M54, M48, or M42 with the included adapters. It doesn’t stop there however — as this wouldn’t be a true astrophotography dedicated telescope without automatic focus support! Out-of-the-box the CarbonStar RC focuser provides easy mounting points for most all popular bracket-style electronic focusers like the ZWO EAF, making upgrading your focusing system a breeze.

Not Just for Imaging
While the CarbonStar series, and Ritchey-Chretien telescopes, are primarily geared towards imaging, this by no means makes the CarbonStar 6″ RC a one-trick pony! This compound reflector in a carbon fiber OTA is a perfect for a grab-and-go visual scope with a large aperture, dew fighting design, and portable mount friendly weight. In addition to all the imaging upgrades, the linear-bearing focuser still has 2″ accessory compatibility, as well as a 2″ to 1.25″ adapter in the box to allow for all your favorite visual observing gear. Simply add the Apertura 2″ Carbon Diagonal and your favorite eyepiece, like the Apertura Super-Wide Angle 26mm eyepiece (both sold separately) for a great visual experience!

Carbon Fiber Construction
Bringing the excellent optics and focuser together is the CarbonStar 6″ Ritchey-Chretien’s premium construction! Sturdy steel assemblies for the primary, secondary, and focuser are mounted in a carbon fiber tube, providing a rigid, but lightweight, platform for these critical components. Carbon fiber isn’t just a lightweight steel OTA alternative however, it is also more thermally stable! This is owing to a lower coefficient of thermal expansion, allowing you focus more imaging and less on readjusting focus. Apertura has additionally packed this OTA with knife-edge baffles, increasing the optical performance by helping block stray light from reaching the 6″ optics!
