BIG Mars Opposition this Month!

Earth and Mars orbit diagram representing how the opposition distance (blue lines) between the planets (Earth = green and Mars = red) can vary depending on where in their orbits the opposition takes place.

At the end of this month, on July 27th, Mars will be in opposition and reach its greatest angular diameter — 24.3-arc-seconds — for the year. This is the best opposition since 2003. It’ll be greater than 21-arc-seconds tonight and well worth observing. For an explanation as to why some oppositions are better, what to expect from this year’s event, and accessories to better view and image Mars, see our blog post: Mars Opposition 2018 Preview.

Every Tele Vue 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. All Tele Vue eyepiece designs are proprietary and are manufactured in factories in Japan and Taiwan that do not make competitive products. To assure outstanding manufacturing and flawless image quality, our in-house NY staff performs optical and cosmetic testing on every eyepiece made, using our patented 5″ f/4 flat field “MPT” test refractor.  We are pleased to offer a Lifetime Limited Warranty on all eyepieces, Barlows, Powermates, and Paracorr products for the original owner. You also have the security of knowing that every current Tele Vue eyepiece can be repaired, serviced, or cleaned at the factory.
