Laser Azimuth

Read More
  • Pieces of the laser unit, prior to assembly.  The laser module is a Coherent 5mW 670nm unit, with glass optics.  It is designed to run off 5V, but is easily powered by voltages ranging from about 3-6V.  This unit is powered by a single Li-ion cell at ~3.7V.

NOTE:  To my dissapointment, at the final polishing stage, I lost grip on the piece and the polishing wheel grabbed it, processed it through the grinder and then across the shop.  I removed the majority of the damage, but some were too deep to remove, without re-machining the part.  A scratch is seen in this view.  Some flat spots are seen in other views.  

Acknowledgement:  I wanted to thanks Don Goldman, (of Astrodon.com), for his suggestion of this device.

  • The assembled laser housing and power cable (less battery connector). Note the flat spot, on the upper left case of the rear of the unit - see the first photo for a description.

  • Another shot of the assembled laser housing, but also including the steel buffer plate (to prevent marring the mount's anodized finish), and a piece of double-sided tape, which secures the housing for more repeatable results. Note a couple more flat spots and a larger gouge - see the first photo for a description.

  • A shot of the laser, mounted on an Astro-Physics Mach1GTO.  The socket head cap screws seat against a steel shim, which is padded (on the telescope side).  The opposite face contains 2-sided tape to prevent marring and also to help secure the laser in position
