The optics of these telescopes are made to exacting standards, with high quality materials to ensure top performance. You'll find that astronomical viewing is a delight with these large, powerful 4" telescopes. They offer 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 objects, including galaxies, nebulae and star clusters.

The altazimuth mount is easy to use and has slow motion controls on both the R.A. and DEC. axes. These controls are on flexible cables, to allow for quick and easy pointing and tracking.

For terrestrial use, you can enjoy views from your own backyard or take your telescope out in the field to enjoy the natural environment, up close.

The C102-HD is mounted on the CG-4 mount, a very rigid German equatorial mount. A counterweight, latitude scale, setting circles and slow motion controls on both axes are standard.
