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.
We noticed some unique images on AstroBin.com employing our Tele Vue-NP127is and Tele Vue-85 scopes to simultaneously image the same target. The images from the two scopes were combined to create the final image — with fantastic results! All the image locations are given as “Tom’s Driveway” in Terre Haute, IN. Intrigued, we contacted the imager (“Astrovetteman”) to learn how he settled on this technique for many of his images. So we turn over our blog this week to astrophotographer Tom Peter and his dual-scope driveway setup.
All Tele Vue telescopes now come standard as optical tube assemblies (OTA) that can be turned into “complete” units with optional, customized accessory packages. The package costs can be substantially less than pricing each component individually. This blog takes you through the changes for the Tele Vue-60, Tele Vue-76, and Tele Vue-85 models. Accessory packages for the larger scopes will be covered in a future blog.
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.
People are rightfully proud of the heirloom quality build and performance of our scopes. This post looks at the various images of Tele Vue scopes posted on social media feeds this year.
A recent favorite of ours was this painting of a Tele Vue TV-85 by Instagram user @h.chiharandy.

Tele Vue telescopes spread out along the center-line of the Monday, August 21, 2017 North American Eclipse. Our employees and friends report on their eclipse experiences. Our first report is from Peter Carboni, our webmaster and social media blogger. He followed the weather trend before selecting his center-line observing location just 4-days before the event!
After driving 14-hrs Sunday, from the Hudson Valley of NY to a hotel outside of Knoxville, I awoke at 3 a.m. Monday morning for the final 90-min journey to my observing site. At 6 a.m. I arrived in Tellico Plains, Tennessee — population 941 — a farming community in the foothills of the Smoky Mountains that abutted the Cherokee National Forest. It was also near the center-line of the eclipse and promised about 2’ 37” of totality.
Aquamarine “cotton balls” and “tadpoles” with sinewy tails cross a star-filled night-sky. That can be your initial impression of Mike Broussard’s comet-loaded flickr photostream. His recent images include the passage of comet Johnson, 41P/TGK, PanSTARRS, & Lovejoy. (The greenish comet color is provided by the glow of ionized cyanogen and diatomic carbon shed by the comet.)

After the penumbral eclipse of the new moon on February 11th, we have an Annular Solar Eclipse just a half-lunar-cycle later. Unlike the lunar eclipse, this one will need proper filtering to observe naked eye or through scopes. The eclipse is annular because only the central part of the sun is obscured, leaving a thin ring (annulus) of light around the edge. This happens because the moon’s orbit brings it closer and further from the earth — so its angular size from earth can vary from 29.4-arc-minutes to 33.5-arc-minutes. The size of the sun hardly varies from 32-arc-minutes due to the small eccentricity of the earth’s orbit. Thus, the moon can appear to be bigger or smaller than the sun according to the circumstances. Continue reading “Countdown: Annular Solar Eclipse Feb. 26, 2017”
