Sapphire Galaxy III Laser, Remote Cable Switch, ASTRO-1 Telescope Mount

The Z-Bolt® Sapphire Galaxy III (SG-3) is built for use in extreme temperatures. We have placed our new design blue laser diode in a beautiful casing suitable for astronomy or scope mounting; operates in low temperatures ( Down to 10 Degrees Fahrenheit) without dimming or degradation. Projects a brilliant sapphire blue laser beam and dot. Visible beam at night - dot only during daytime hours. Three (3) hours constant on operation.

The Sapphire Galaxy III is the product of new design technologies and manufacturing efficiencies. Z-Bolt® Sapphire Series laser pointers are fabricated with InGaN semiconductors, which emit blue laser light without frequency-doubling. Blue laser is eye safe - IEC Class 3R and FDA Class IIIa.

ASTRO-1, Laser Telescope Mount - Aircraft Grade Aluminum

Astronomy Bracket ships with 4 mounting screws; o-rings to prevent laser from sliding out; installation manual. Bracket has quick release mechanism to allow for easy shipping or storage. Black finish, constructed of aircraft grade anodized aluminum.

1] On most Schmidt-Cassegrain telescopes (reflectors), the base is a drop-in replacement for the stock finder bracket, and can be held in with the original screws, or those provided.
2] On Newtonians (refractors), four screws are recommended for the ASTRO-1.

RS-2 Cable Switches [Choose 6", 15", 30"]

Remote cable switch to activate blue laser pointer without touching telescope when aligned as a star finder. Prevents unwanted movements that affect delicate finder alignments. For use with blue lasers in finder mounts and alignment setups. Designed for the outdoors; rugged and reliable; dirt and moisture resistant. Cable switch can be "velcro" attached to telescope body; or allowed to dangle freely.
