This iOptron GoTo Mount Telescope Package is currently on sale through March 31st!  Enjoy substantial savings on a nice imaging package that includes the 6" f/9 RC (Ritchey-Chretien) telescope, a CEM26 Computerized Equatorial Mount with AccuAlign polar scope, hard case and tripod, and several accessories, including a star diagonal, eyepiece, and finder!  Below you will find more information on each of the main components!

iOptron Photron RC6 - 6" Ritchey-Chrétien Telescope OTA

First up, the Optron Photron 150 mm (6") Ritchey-Chretien (RC) Astrograph with a focal ratio of f/9 and a focal length of 1370 mm.

The iOptron® Photron Ritchey-Chrétien design telescope features a low thermal expansion quartz primary and secondary mirror with 99% reflective dielectric coatings. The RC optical design delivers results free of coma, spherical and chromatic aberration, perfect for color or monochrome imaging.

A fixed-position primary mirror cleverly eliminates image shift that occurs from focusing with other telescope designs. The iOptron RC6 150 mm Astrograph comes with a 2" dual-speed linear-bearing Crayford focuser. Three focuser extension rings are provided for a “flex-free” solid extension as a means to take up any unneeded back focus. Its steel tube is equipped with knife edge baffles to diminish contrast reducing stray light, improving the instrument in both visual and imaging uses. This iOptron Photron 150 mm Ritchey-Chretien (RC) RC6 Astrograph model comes with one Vixen style dovetail mounting plate.

Like their predecessors, the CEM26 mounts were designed with portability in mind, weighing in at only 10 lb. But, it can support up to a 26 lb payload an incredible 2.6 mount weight-to-payload ratio. The key to providing such an impressive ratio is the "CEM design" which focuses the mount and payload weight directly on the center of the tripod rendering “natural stability”. The center-balanced design mount puts the weight of the payload at the center of gravity allowing for greater mechanical mount stability. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. And polar aligning is quick and accessible all the time, because the polar scope is not blocked by the declination shaft.

In addition, iOptron has added features for convenience and functionality. A positive lock gear engagement system (easy to use even when wearing gloves), built-in Wi-Fi, enabling unparalleled connectivity, and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. The CEM26, Model C26B Center-balanced Equatorial Mount from iOptron delivers precise pointing and accurate tracking. The CEM26, Model C26B sets a new standard for compact equatorial GoTo mounts.

The iOptron CEM26, Model C26B Equatorial Mount is equipped with the latest advanced GOTONova GO-TO technology, which means it is now one of the most powerful and accurate GO-TO mounts available. Its database includes over 212,000+ objects! The Go2Nova Hand Controller is intuitive and very easy to use. Its large 4-line LCD screen simplifies the process of setting telescope parameters and locating objects, to make the astronomer's task even easier.

This CEM26, Model C26B mount has an AccuAlign Optical Polar Scope installed for quick and easy polar alignment. It also includes a 1.5" heavy duty stainless steel tripod and two counterweights (5 & 10 lb).
