Details
This telescope was carefully designed for the more advanced astronomer and feature exquisite optics on a heavy-duty mount. The optics of this telescope are made to exacting standards, with high quality materials to ensure top performance. The C4-R offers a 63% increase in image brightness over 80mm models, with the larger aperture delivering incredible images of the Moon; Saturn and its ring structure; Jupiter and its belts; and hundreds of deep-sky ibjects, including galaxies, nebulae and star clusters.
This telescope is mounted on the CG-4 mount, the mount features precision gears for extremely smooth motion. A counterweight, latitude scale, setting circles, and slow motion controls on both axes are standard, so you have a fully loaded telescope right from the start.
