ASTELE 70 (Astronomical Telescope / Spotting Scope)

ASTELE™ 70 with
optional tripod.

The ASTELE™ 70 is a versatile astronomical telescope, spotting scope and telephoto lens. Can be used for astronomy, target spotting, bird watching, nature studies etc.

The optical design of the ASTELE™ 70 is Maksutov Cassegrain. This design uses a meniscus optical correcting lens which produces the highest possible quality image with it’s primary mirror, and which seals the telescope from dust, dirt, etc., contaminating the optics of this instrument. Plus, it makes this professional quality instrument more rugged and also keeps the optical elements from coming out of alignment.
Another important feature is that this instrument uses a mirror to magnify the image not a lens.
Whether you are looking at a black-capped chickadee or the planet Saturn, the ASTELE™ 70 will provide you with razor-sharp images. The ASTELE™ 70 uses U.S. standard 1.25" O.D.-sized eyepieces (hundreds are available). It's so handy that you will want to take it with you everywhere. Finish: black or blue star map (shown).
Case: black nylon.
Photo adapter for standard cameras and lens shade are available separately.
