Green Laser
Green Laser

Much more powerful than a red laser, a green laser can be seen for miles. Used at night, a bright green beam is visible as far as your eye can see. Point your laser towards the sky, and anyone within a 10 foot radius will be able to see exactly what you’re seeing. Used indoors, only the green dot is visible, making it a noticeable yet non-distracting presentation pointer. <5mw. FREE SHIPPING!

The Night Sky Planisphere (Non-Distortion)
The Night Sky Planisphere (Non-Distortion)

A planisphere is a star map that allows you to see what stars are in the sky on any given night of the year.
The Night Sky is NOT a conventional planisphere! No flat map can remove all distortion, but The Night Sky eliminates over 90% of the distortion inherent in conventional 1-sided planispheres. (Shipping $2) Click here for more information. (Currently only 30 to 40 degree latitude is in stock)
