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-5 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.
