About the Sky Mentor 7mm-21mm Zoom Eyepiece - 1.25"...

The Sky Mentor 7mm to 21mm Zoom Eyepiece is like getting a whole set of eyepieces rolled into one!


Imagine looking at the planet Saturn and being able to zoom up close and see the rings without having to switch eyepieces! Or... the lunar surface. Imagine looking into a crater and zooming in for more details. The experience can be akin to being in a spaceship approaching the object.


Early this morning, I did just exactly that. At twilight, while the world was just waking up, I observed the rings of Saturn through the Sky Mentor 7mm to 21mm Zoom Eyepiece. Not too far away, the gibbous Moon, in all its glory! I wish everyone could experience the exhilarating feeling of this type of observation... Well, now you can with this low cost, quality zoom eyepiece.


And you too can do the same with YOUR telescope. No matter the brand, Meade, Celestron, Orion, Bushnell, Bausch & Lomb, etc.. this Sky Mentor 7mm to 21mm Zoom Eyepiece will work!


Here is the problem: Most zoom eyepieces today are way too expensive, I am not sure why, but the manufactures must have some pretty huge mark-ups. Either that, or they are cheap and poorly made. Utilizing the latest technologies in optical manufacturing, with state of the art equipment, we were able to come up with a top of the line zoom eyepiece at a reasonable price.


How it works: Simply insert the Sky Mentor 7mm to 21mm Zoom Eyepiece into your telescope focuser, and rotate the knurled barrel to any of the focal lengths from 7mm to 21mm .Iincluded ranges are: 7mm. 9mm, 11mm, 15mm, and 21mm! Yes, thats right, its like having 5 different eyepieces for the price of one! Even combine it with a barlow lens to further increase the magnification range! (note: A barlow lens doubles the power of any lens inserted into it)
