Tele Vue-NP101is Imaging the Skies of Rhode Island!

We found unique takes on familiar deep-sky objects on David Augros’ AstroBin account. They were taken with our Tele Vue-NP101is refractor (photo/visual, 101mm, f/5.4 APO) using our Large Field Corrector (LCL-1069) and modified Canon EOS 6D DSLR.

The first impression is of a dark canvas, sprinkled with white pinpoints and bright cloud-like strokes of gold, red, and blue. Brilliant jewels were seated in the colorful clouds and several dense clusters of diamond dust were scattered on this celestial painting. Dark clouds emerge from the canvas and contrast themselves among the dots and colored hues.

We asked David how he got involved in astro-imaging and why he choose this scope. He told us in his own words.

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.

Tele Vue NEW for 2018: NP101is, NP127is OTA Accessory Packages, SCT Rich Field Kits, & Diagonal Packages

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. In a prior installment we discussed the packages for the Tele Vue-60, Tele Vue-76, and Tele Vue-85 scopes. Here we’ll take up the multi-purpose Imaging System, or “is,” scopes and their associated accessory packages.

Tele Vue NP127is and NP101is scopes and accessories we’ve turned into packages for visual observing.

Tele Vue Telescope Shows and Indoor Solar Viewing

Astrofest 2018

If you’re in the New York metro area the third week in April, we’ve got a lot to show you at two back-to-back shows we’ll be at: the annual Northeast Astro-Imaging Conference (NEAIC: April 19 & 20) and Northeast Astronomy Forum (NEAF: April 21 & 22) — both in Suffern, NY — about an hours drive northwest of New York City.

We’ll exhibit an updated night vision demonstrator to show you the benefits of using our visual and smartphone accessories designed for the Tactical Night Vision Company (TNVC)  night vision monocular. This is the system that just won a Sky & Telescope 2018 Hot Products Award. In the coming months, Sky & Telescope will be publishing their test review of the system. You can get a preview of this review on page 63 of the April 2018 issue and looking at the image below.

#televue40: Our Scopes

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 TV-NP101is Relativity Experiment: Data Update

Artwork inspired by images and data from Dr. Bruns’  eclipse experiment website.

This is an update on Dr. Don Bruns’s attempt to measure star-position deflection with our Tele Vue-NP101is telescope during this past August’s solar eclipse. His goal was not just to duplicate the famous 1919 experiment (by Sir Arthur Eddington that proved Dr. Einstein’s General Theory of Relativity), but to demonstrate that portable, readily available amateur equipment can produce results that rival that of professional hardware from past decades. His experiment was to “determine Einstein’s deflection to an accuracy of 1%, the best optical measurement of the deflection ever demonstrated.” He points out that a professional attempt at the 1973 eclipse achieved an error of 11%. See our blog post “Tele Vue NP101is to Test Einstein’s General Relativity” for more background.

Cherry Springs Star Party: Afterglow with the NP101

What I like about star parties is meeting and speaking to all the fine people that travel long distances for great observing experiences.  Sometimes the conversations continue after the event. This is an excerpt from a note I received from Bob Danko, of Warren Ohio, soon after returning from the Cherry Springs Star Party this June.

Tele Vue TV-NP101is Relativity Experiment Update

Optical physicist Dr. Don Bruns recently updated Tele Vue on his preparation for measuring star deflections near the sun during August’s total solar eclipse. As explained on our March 21st blog post (“Tele Vue NP101is to Test Einstein’s General Relativity”), when first measured at the 1919 total solar eclipse, the deflections confirmed Einstein’s general theory of relativity (and made Einstein a household name). Over the years though, the accuracy of the 1919 experiment has been called into question and subsequent visual light attempts during eclipses has not been “stellar”. According to Dr. Bruns, “astronomers last repeated the experiment in 1973, achieving an error of 11%”. This time around he hopes to achieve an accuracy of 1% using readily available amateur equipment. Instead of hauling a big 16” diameter refractor to the eclipse site – as in the 1919 experiment – he’ll be using a much more compact Tele Vue NP-101is telescope.

The Tele Vue NP-101is was selected for an historic project by Dr. Don Bruns: to repeat the 1919 experiment of measuring star deflections during a solar eclipse that confirmed Einstein’s theory of Relativity.

The experiment will take place for the August 2017 solar eclipse, with Don using the NP-101is and FLI Microline 8051 CCD camera mounted on a Software Bisque MyT Paramount and field tripod.
