From Tom’s Driveway: Tele Vue-NP127is & Tele Vue-85 Simultaneous Imaging!

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.

Tele Vue TV-60: Surprisingly Versatile Mini APO Refractor

Tele Vue-60: Compact Travel Scope with Imaging Capability
This week we turn our attention to the capabilities of our smallest telescope: the Tele Vue-60. This 60-mm aperture, f/6, APO refractor offers users a maximum 4.3° visual field and a potential of reaching 150x —all this in a package just 10″ long and a svelte 3-lbs. Due to its diminutive size, it is easy to overlook this instrument when shopping for a quality APO travel-scope. But, many users have been pleasantly surprised at the capabilities of this small refractor.

Tele Vue-NP127fli Imaging the Skies Over Austria

We’ve been following the great work of astro-imager Patrick Winkler from Austria through his Instagram account @cel_objects.  Among the varied camera lenses and scopes used for these images was our own Tele Vue-NP127fli astrograph. The strength of this scope is wide-field imaging and his work in this area is exemplary. 
 
Double Cluster(NGC 869 & NGC 884) image is copyright by Patrick Winkler. Tele Vue-NP127fli astrograph equipped with FLI MicroLine ML 16200 monochrome camera, FLI CFW 2-7 filter wheel, and FLI Atlas focuser was mounted on an Astro Systeme Austria Direct Drive ASA DDM60 Pro mount. Exposure was as follows through RGB filters (minutes): 63 63 63.
For instance, with the NP127fli  he was able to perfectly frame and capture the spirit of the NGC 869 and NGC 884 in Perseus as twin clusters of sparkling blue-white diamonds, with a smattering of glowing red-rubies, punctuating the black velvet sky background. The Double Cluster never looked so good!

Dr. Bruns at NEAF 2018

David Nagler, Dr. Bruns, the NP101is used for the experiment, and Al Nagler.

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.

Q&A with Tele Vue’s Al Nagler

This interview of Al Nagler by Brian Ventrudo was published in The Equinox newsletter of AstronomyConnect.com on October 31, 2017. Reprinted with permission

A Q&A with Al Nagler
Looking Back (and Ahead)
with Tele Vue’s Co-Founder

David and Al Nagler

Introduction

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!

Tele Vue TV-60 is Not Just for the Birds

We are proud of the SmartMoney Award the TV-60- received upon its introduction.

This is the counterpoint to our Tele Vue is for the Birds blog post this past spring. Yes, you’ll find that the TV-60 is a great grab’n go astro scope too! 

Our award winning, high performance, super-compact Tele Vue-60 is worth considering for those looking for a super-portable APO refractor. It fills many niches including travel, super-finder, day/night scope, and is a great telephoto.

It accomplishes all this APO-goodness in a very small 60mm, f/6 form-factor: just 10″ long without diagonal!

Tele Vue TV-60 is a 60mm, f/6 APO with 4.3° field of view (32mm Plössl).

Tele Vue Product Spotting #1

From time-to-time we see Tele Vue products juxtaposed with other interesting brands. This is a roundup of what we’ve run across so-far this year.

Tele Vue Packed Turret

Matthew Hodgson’s Alpha Lyrae website had a review of the nPAE (Nottingham Precision Astro Engineering) 6061 Medium Turret eyepiece holder. The shot below from the review has all six turret slots filled with our eyepieces.
