Special Astronomy Kit!


Extreme Temperature Operation 14° ~122°F


The Z-Bolt® BTG-2S-P-XT is constructed of high quality steel & brass components and utilizes a glass lens for superior laser performance. This model includes new 515nm semiconductor laser technology!  No IR Light Filter required.   Satin lined carry & gift case. Constant on/off click switch; telescope mountable; visible beam & five (5) mile range (at night). Add a Z-Bolt® cable switch for remote activation.


Z-Bolt® Certified Power Output Certificates . . .


The BTG-2S-P-XT features guaranteed Z-Bolt® Certified Power for the brightest possible daylight dot; most visible nighttime beam. Each Z-Bolt® Certified Power green laser pointer is factory tuned & calibrated, then tested & certified on a laser power meter - all tested units ship with a Laser Power Output Certificate.  Only premium Z-Bolt®  Certified lasers are rated at 4.0 to 5.0 mW power output and are 2 to 3 times brighter than standard Class IIIa units. 


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.


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


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.
