Mars Madness 2018 Eyepiece Rebate for U.S. Customers!
Mars will be growing rapidly in apparent diameter in the weeks up to the big Mars Opposition on July 27, 2018. With Mars peaking this summer, Tele Vue Optics is making it easier to take a peek with rebates on 13mm and shorter focal length eyepieces for customers in the USA, US Territories, and those with APO/FPO Addresses.
Furthermore, the Association of Lunar and Planetary Observers notes that “Mars will exceed 24-arc-sec in diameter between July 23rd and August 9th, 2018. This is 97 percent of the maximum of 25.13-arc-sec diameter attained during the last of the ‘favorable’ apparitions, which occurred in 2003.” In fact, due to orbital eccentricity, Mars and Earth continue to draw ever-closer after this opposition, with the distance shrinking by another 111,000-miles / 179,000-km when they are nearest on July 31, 2018!

About Tele Vue Eyepieces
Every Tele Vue eyepiece is visually tested at f/4 to ensure the sharpest full field possible. It is the nature of optics that being the best in fast scopes also always assures the best performance in “slow” scopes. The finest performance requires the finest materials such as high index lanthanum and fluorite type glasses, in some cases costing up to 15x more than ordinary glass types. At Tele Vue we ask “how can we make it better”, rather than “how can we make it cheaper.” We think you’ll agree that the views are worth it. Every eyepiece is fully multi-coated, has blackened lens edges and anti-reflection threads for maximum contrast. Chrome plated barrels, which resist scratching and marring better than black anodized barrels, include safety undercuts and threads for filters. Upper barrels are black anodized aluminum with a rubber grip ring, engraved identification, and fold down rubber eyeguards.
We stand behind our product and are pleased to offer original owners a Lifetime Limited Warranty on all eyepieces, Barlows, and Powermates products.
