Available in either 1.25" or 2" sizes the mirrors inside these diagonals have undergone a special high-reflectivity multi-coating process, allowing them to reflect 99% of the precious gathered starlight, providing exceptional brightness and contrast. (Standard diagonals typically reflect 90-95% of light).
Designed to fit into a standard 1.25" eyepiece tube. This binocular attachment features high quality BaK-4 prisms for clearer, sharper images. An excellent accessory which helps to reduce eyestrain. A x2 specially-designed Barlow Lens is included which effectively doubles the magnification of eyepieces used.
The Telrad is the best-selling non-magnifying finder for Dobsonians, equatorial reflectors, refractors, and Schmidt-Cassegrains alike. The Telrad projects a series of concentric red rings (4 degrees, 2 degrees, and one-half degree in diameter) on a tilted clear viewing plate at the top of the finder. These circles make it easy to starhop from object to object. If a galaxy is 10 degrees north of a known star, for example, two 4 degree Telrad jumps and one 2 degree jump from the known star will take you to that galaxy in seconds. The half-degree circle makes it easy to quickly center a computerized scope on guide stars for start-up alignment, and to center on planets, comets, and deep space objects if you’re scanning the sky manually. The red circles can be seen from virtually any distance behind the Telrad, from two inches to two feet, so eyeglass-wearers can easily use the finder. This spare base for the ever popular Telrad finder enables the finder to be used on more than one scope. Simply attaches via self adhesive pads (supplied) or fixing holes. Designed to fit nearly all tube diameters from 4" upwards.
