   TAL telescopes: TAL-2
Novosibirsk Instrument Making Plants logo

The TAL-2 is a magnificent example of a 6-inch f/8 Newtonian reflector, for generations the traditional instrument of the serious amateur astronomer. The quality of construction leaves nothing to be desired: premium optics in fully adjustable cells mounted in a seamless aluminum tube; a sturdy heavy-duty equatorial mounting complete with engraved setting circles, motor drive, and manual slow motions on both axes; rotating felt-lined rings; an 8x50mm finderscope with detachable dovetail base; fitted wooden storage and carrying cases. At the customer's request, a very rigid metal pedestal or a hardwood tripod will be provided.

You'll be impressed with the attention to detail. The adjustable declination axis counterweight is secured with an intricate collet mechanism; the rack-and-pinion focuser features a unique tension adjustment so that it can easily carry the load of a camera; all fasteners are captive so that they'll never get lost in the dark.

A full complement of accessories are included: a sun projection screen; solar, lunar, and color filters; three eyepieces of 42mm, 25mm, and 15mm focal lengths; a 4x Barlow lens; an adaptor for photography with a 35mm SLR camera.
