Telescopes: TAL-100RM |
|
The heart of this classical 100mm (4-inch) f/10 refractor is a multi-coated air-spaced achromatic doublet objective lens that is well-corrected for both spherical and chromatic aberrations. The aluminum tube contains carefully ray-traced baffles to eliminate stray light, providing crisp, high-contrast images. The TAL-100R excels for observations of the Moon, planets, and double stars.
A dewcap, 6x30mm finderscope, and two eyepieces of 25mm and 10mm focal length are included, as well as a 90-degree star diagonal for comfortable observation of objects near the zenith.
The tube assembly is supported by a sturdy equatorial mounting that features manual micrometric slow-motion controls in Right Ascention and Declination. At a modest additional cost, a motor drive in right ascension can be provided (as model TAL-100RM). At the customer's request, either a metal pedestal or hardwood tripod is included, as well as a fitted wooden carrying case.
