At only 30-lunar distances from Earth, Comet 46P/Wirtanen brightened to magnitude 3.6 as it brushed by our planet on December 16th — just 4-days after perihelion (closest to sun). The anticipation of this close pass-by engaged the attention of many amateurs that observed and imaged this “dirty-snowball” in the weeks leading up to the fly-by. But the most iconic image of this comet’s apparition was made two-weeks before its closest approach to Earth.
With the moon a waning crescent, it is a good time to pick out some faint objects in the sky.
On Friday, September 7th, Neptune rises opposite the sun and is closest to earth. Being in the sky all-night, and at it’s brightest, presents a good opportunity to sight this rarely-seen telescopic planet. Unlike the naked eye planets, you’ll have to crank-up the power to make sure you’ve really found it. Even at 100x it just looks like a magnitude 7.8 star. So don’t expect to see a Voyager 2 quality image through your eyepiece.
We were honored that Northeast Astronomy Forum (NEAF) speaker Dr. Donald Bruns was able to visit in our booth over the two days of NEAF 2018.
Saturday, April 21, at noon, Dr. Bruns stepped onto main stage at NEAF in front of a standing room only audience. His talk was titled: Einstein was Right! Completing the 1919 Relativity Experiment at the 2017 Solar Eclipse. Over the better part of an hour he explained how Einstein’s General Theory of relativity predicted the bending of light in gravitational fields and how astronomers have attempted to photograph stars near the eclipsed sun to verify the theory.
At the beginning of 2017, in honor of Tele Vue’s 40th year, we asked you to tag your social media images taken with or taken of Tele Vue equipment with the hashtag #televue40. You did so and there are too many images to highlight them all, but we’ll bring you a few at a time though these blog posts.
This installment features gorgeous images of Deep-Sky Objects (DSOs) taken with Tele Vue hardware. Some of the images are in Hydrogen-alpha (b&w) and others full-color. Exposure times range from hours (one night’s work) to over a day (several nights work)!

Roger Hutchinson is a noted amateur astrophotographer who produces much of his planetary, solar, and even comet work from what he admits are the “light polluted skies of southwest London”. His imaging work is showcased on his aptly named The London Astronomer website as well as on flickr, Instagram, Twitter and Facebook.
Roger’s interest in imaging the sky runs back to the age of 11 and has culminated as the recent recipient of the Insight Astronomy Photographer of the Year award in the Planets, Comets & Asteroids category for 6-month-long effort to capture the evolution of the phases of Venus. Some of Roger’s social media profiles include a picture of the “Captain” standing with “Bleep” and “Booster” from the BBC animated series “Bleep and Booster”. He says “I have two kids myself so thought the image was kind of appropriate. Suitably space related and brings back some happy childhood memories.”

A Q&A with Al Nagler
Looking Back (and Ahead)
with Tele Vue’s Co-Founder
When Al Nagler talks, amateur astronomers listen.
Nagler, of course, is a legend in the amateur astronomy community, the founder of Tele Vue Optics along with wife Judi, and inventor of the Nagler eyepiece. For two generations he’s been a fixture at star parties and astronomy expos where he dispenses wisdom and demonstrates his latest optical creations, all while establishing bonds and friendships with hundreds of stargazers over the years with his combination of razor-sharp technical acumen and boundless enthusiasm.
Al was beguiled by astronomy and stargazing after a visit to Hayden Planetarium with his father in the late 1940s. He grew up in the Bronx and had the talent and good fortune to attend the famous Bronx High School of Science, the alma mater of thousands of renowned engineers and scientists, including eight Nobel Prize winners. As part of a class project, Nagler used the school’s facilities to design and build an 8-inch f/6.5 Newtonian reflector that weighed 350 lbs! In time, Al put his talents to work at the nearby Farrand Optical Company from 1957-1973, where he helped develop the large and complex optical systems for NASA’s Gemini docking and Apollo lunar landing simulators. Not a bad way to make a living!
