Duet® Sapphire Blue Laser, Cable Switch, ASTRO–1 Scope Mount

The Duet® Sapphire (D–5-BL) is truly innovative. Most laser pointers have either a momentary push button or constant on click switch for hands free operation. The Duet® Sapphire has both. The oval button is a momentary pressure switch for hand held pointing; the square button slider switch allows for hands free use. The unit features true blue 445455nm blue laser light (not 405nm violet/purple) The new design blue laser module operates on 1 pc CR123A lithium battery. Projects a brilliant sapphire blue laser beam and dot. Visible beam at night - dot only during daytime hours. Six (6) hours constant on operation.

The Duet® Sapphire is the product of new design technologies and manufacturing efficiencies. Blue laser is eye safe - IEC Class 3R and FDA Class IIIa. Ships with free Z-Bolt® lanyard for neck or wrist, black nylon belt carry pouch (MOLLE Style)

Astro–1, Anodized Aluminum

The ASTRO–1 features a quick-release laser bracket for transportation and storage. The bracket also includes a precision T-style dovetail that maintains alignment when re-attached. Made from solid aircraft grade aluminum, the ASTRO–1 is engineered for a lifetime of use. Holds lasers up to 23mm OD; weighs 5oz.


Astronomy Laser Bracket ships with your choice of three (3) mounting base plates:

Reflector Telescopes

Wide 2.35“ Base. With a radius-cut of 9.25”, the base mounts snugly to virtually any reflector. Pre-existing holes with center-to-center spacing of 1.0“ to 2.1” may be used to mount the base using two (2) screws; or four (4) screws with 1.75" center-to-center spacing may be used. Mounting hardware (8–32 screws/nuts) included.

Refractor Telescopes

Features a smaller base to take up less space on your refractor. With a radius-cut of 1.75“, the base fits snugly on most refractors, and is mounted with industrial-strength double-sided tape, included. Base is 1.12” wide at the bottom; 0.88“ wide at top and 1.5” long. Height to ring-top is 2.6".

Tripod Base Plate

Mount your Laser Bracket to any camera tripod with standard 1/4–20 threads.

Remote cable switch to activate green laser pointer without touching telescope when aligned as a star finder. Prevents unwanted movements that affect delicate finder alignments. For use with green 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.
