Proxima 31 The first in the new 2" wide angle series offered by GTO. The Proxima 31 utilizes a hybrid design of a five-element design featuring a 71° extra wide field of view. The new Proxima 31 is the answer to those big name wallet busting wide fields. These special eyepieces are computer designed to keep visual aberrations to an absolute minimum. Care was taken to minimize spherical, chromatic aberration, field curvature, coma, astigmatism, distortion and spherical distortion. Not recommended for faster than F/5 optical systems. The 31mm focal length has a comfortable 20mm of eye relief with soft rubber eyecup for eyeglass wearers and to keep out extraneous light. The inside surfaces and edges of all lenses are blackened, to keep out reflected light. Outside surfaces are flat black, with rubber grips for secure handling. These eyepieces also feature a wrap around ribbed rubber security grip. Threaded barrels accept standard 2" (48m) thread-in filters. The Proxima 31 is shipped in StarDust, shock resistant case. We guarantee a 6 degrees wider field than most brand name wide fields. Please compare with the best $250-$300 eyepieces on the market today for contrast and resolution and of course price. As always, the Proxima 31 is covered by our Hands on Optics money back guarantee.
New Proxima Zoom Eyepiece from Hands on Optics. A standard 1.25" , 8-24mm with extraordinary contrast and resolution. We have tested it with everything from 5" APOs to 4" reflectors and it is excellent. Outperforms the current Televue/Vixen/Meade/Celestron Zoom at high powers at ½ the cost. Remarkable center of field contrast and resolution that rivels the best known planetary eyepiece. Money back guarantee. The field of view is 67 degrees at 8mm to 40 degrees at 24mm. Comes with a screw up hard rubber eyecup, like a Pentax eyepiece and fitted in a StarDust screw down case. 2 year warranty.

"For a beginner on a budget, I can indeed recommend the 25mm GTO Plossl by itself and in combination with the 2X GTO Barlow. They are both good quality items, and they do seem to hold their own against more expensive counterparts. Considering that the GTO's are half or a third the price of the competition, they are extremely good values from what I have seen. Of course, mine is only one opinion; but my opinion is that they are keepers." (Darwin Bagley's "Magnum Opus" on http://www.weatherman.com/)
