A customer recently called because his vintage Tele Vue Renaissance telescope needed some tender-loving care. The Renaissance was our second model, put on the market after the 1981 “Multi-Purpose Telescope” (MPT). The customer’s scope was built in 1985 and is from the initial production design with a bolt-on focuser. After discussing the obvious issues that needed addressing and our evaluation process, he decided it would be worth it to him for us to have a look at the scope.
When we received the scope, the most obvious troubling issue was the focuser. It was unusable. The pinion shaft was badly bent and two of the three teflon runners supporting the draw-tube along its travel were missing. The outer surface of the objective showed years of grime, and all of the brass components were heavily oxidized. The optics, however, were only slightly mis-aligned, producing a mildly flaired star shape at high power, but the image was still serviceable for terrestrial and deep sky viewing. Sadly, after a complete optical and mechanical inspection, we concluded that it just wasn’t worth the effort and expense to revive the telescope. That, however, was not our customer’s conclusion.
He gave us the go-ahead and we proceeded to give his 1985, brass Tele Vue Renaissance a new lease on life. A “renaissance” for this Renaissance if you will!
Vic Bradford has owned a brass Renaissance telescope since 2006, about 20 years after he first saw Al Nagler show one at a Riverside Star Party. He regrets not owning one sooner as “the scope uniquely merges the beauty of form and function”. We’ve reprinted some excerpts below from a treatise he sent us on caring for the brass on his Renaissance telescope and brass fittings on his matching Tele Vue Gibraltar mount. He offers a caveat to the reader: “you may find these suggestions overkill and much can be said for simply leaving brass alone so it can develop a nice patina. Like any other fine equipment, though, it benefits from good care and research.”
These instructions are for cleaning and polishing brass lacking a clear-coating. Following these instructions will ruin your coating.
It’s hard to believe that our blog has been posting articles for two solid years already. We didn’t note it at the time, but our post “odometer” rolled past 100 this October. Our 101st post was Tele Vue-NP101is Imaging the Skies of Rhode Island! It featured David Augros’ images from a dark-site on Rhode Island with a Tele Vue-NP101is using our Large Field Corrector and modified Canon EOS 6D DSLR. He chose that scope because it offered “a nice balance between a generous wide field and fine details in my final images.”
Our very portable Tele Vue-76 APO refractor has been popular with eclipse-chasers as well as with users that cross over into spotting and birding. With the popularity of small and powerful dedicated imaging cameras, the performance of the Tele Vue-76 is getting noticed by deep-sky imagers on the go. Case in point, Diego Cartes Saavedra is producing outstanding deep-space images from various locations in the southern-hemisphere with this scope. All his images in this blog post were taken from July through November 2018.
Diego’s study of the Tarantula Nebula and surrounding region in the Large Magellanic Cloud examines the area imaged through different filters. The first image is a monochrome version taken in Hydrogen-α light.
Surfing through the AstroBin site’s collection of user generated astrophotos we were struck at this vivid example of M16 “The Eagle Nebula.” The image has a depth and contrast we’ve never seen before. Created using “Hubble Pallet” filters, the rich blue (Oxygen III) surrounding the “Pillars of Creation” structure is highlighted by the ruddy bland of reds (Sulfur) and greens (Hydrogen-alpha and Nitrogen) in the “folds” of the surrounding dust clouds. The blackness of space at the edge of the dust and gas cloud is preserved against all the colors.

Here’s a little photo blog from the “Rencontres du Ciel et de l’Espace” (RCE) show. The show took place from November 1st through 3rd at the Museum of Science and Industry in Paris and featured over 150 lectures (in French of course) over the three days with vendors spread over two floors. Daily attendance is in the neighborhood of 2,500 people, so it’s a busy show! I’m only sorry that these pictures don’t do the show justice. After all, I’m really there to speak with people, make recommendations, and demonstrate our equipment, not write a blog. 🙂
Imaging a rare celestial event requires advanced planning, the right equipment, and often a lot of post-processing. Tony Cook traveled from the UK to Paphos on the southwest of coast of Cyprus (we suppose for the over 300 sunny days a year) to image the 2004 Transit of Venus with his Tele Vue-85, Coronado SM60 hydrogen alpha filter, Canon 10D camera, and Losmandy GM-8 mount. The 85’s optical capabilities and airline portability often makes it a favorite for amateur astronomers chasing down rare events like this.
It’s almost time to board the plane for my biennial trip to the “Rencontres du Ciel et de l’Espace” (RCE). The show takes place from November 1st through 3rd at the Museum of Science and Industry in Paris and features over 150 lectures (in French of course) over the three days with vendors spread over two floors.
