Jupiter & Venus Conjunction – Nov. 13, 2017

Morning planets group together in mid-November.

Early risers will note that Jupiter & Venus have been approaching each other in the deep-morning twilight of the eastern sky. Jupiter ascends ever higher each morning while Venus settles lower onto the horizon. The two worlds cross paths on the morning of November 13th when they will be about a half-moon width apart.  Continue reading “Jupiter & Venus Conjunction – Nov. 13, 2017”

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.

Subject: 10715 NAGLER (1983 RL4)

We’d like to share with you this nice letter Al received from Roger Harvey recently.

From: Roger Harvey
To: Al Nagler
Subject: 10715 NAGLER (1983 RL4)

Hi Al,

We first met at the Wildacres Retreat, North Carolina mountains, this past April. Despite our lengthy conversation that I will always remember, you never mentioned that you were honored with asteroid 10715 Nagler (1983 RL4).

As luck would have it, my primary effort in amateur astronomy the past 40+ years has been visually identifying asteroids by their position, magnitude, and motion against the background star field.

My observing session for August 16, 2017 happened to include 10715. I saw it at 3:54, 4:32, and 6:28 UT retrograding southwestward in Aquarius at magnitude 16.3. This was ~0.5 magnitude fainter than advertised…not uncommon with higher numbered asteroids. In doing so it was my 5900th asteroid.

My scope is a Lockwood 32” f/4 which (of course!) I couple with your Paracorr Type 1. The 5.5 mm eyepiece yields 676X which is my usual choice. Several times I’ve had to go to 1352X for very faint targets requiring a darker field. Obviously such an effort would be impossible without the excellent optical train above.

Again, it was great speaking with you on the phone today! I am so glad you got a kick out of your asteroid actually being seen by a human (read eyeball, not CCD) (:>). Your joy made my day as well.

2017 Eclipse: Naglers in Nashville, TN!

Observers point at first contact in front of the Tele Vue tent. David Nagler is third from left in green.

If ever there was an event that bound together every living thing on this planet, the disappearance of the Sun during broad daylight reminds us of just how reliant, fragile and connected we are. To be able to share the emotions of that special moment with others reminds us that all the moments we share are special.

Tele Vue-NP127is: Imaging the Skies Over Europe

From a small town in Germany, two hours drive away from the Alps, Panagiotis Xipteras images the sky with his Tele Vue-NP127is. We noticed his exquisite images on social media and asked him why he choose the NP127is for his imaging scope. He tells us below.

2017 Eclipse — the View of a Lifetime! (with the TV-NP101)

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 second report is from Al Nagler’s totality trip to Columbia, SC.

A year ago, Judi (wife and Tele Vue co-founder 40 years ago) planned this eclipse trip, our 4th. I decided, agreeing with Neil deGrasse Tyson’s recommendation, to concentrate on the unforgettable visual experience of totality. Boy was he right!

We reserved rooms at the Hilton Embassy in Columbia, SC and drove there starting on Saturn-Day (pardon my passion for changing the name) August 19th, arriving on Sunday afternoon to meet-up with our good friends Gail and Matt Cowit to share the experience. I immediately found a good parking spot with my car trunk facing a large open area and nearby trees for shade benefit :-).

Neptune Opposition: Sept. 5, 2017

Tonight 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 other 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. Continue reading “Neptune Opposition: Sept. 5, 2017”

Totality in Tellico Plains, TN with Tele Vue TV-85

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.

Countdown: Total Solar Eclipse of August 21, 2017

Tele Vue President David Nagler exiting our building with all his eclipse observing gear in hand.

The media frenzy is growing as the first total solar eclipse to cross the North American continent in decades is closing in on us.

Our Tele Vue President David Nagler likes to travel light. So he built his eclipse observing kit around the Tele Vue TV-60 and Tele Vue Tele-Pod mount. In fact, he’s shown in the image here with not one but two complete telescope setups with a selection of eyepieces and solar viewers. Here’s a complete list of what he is carrying:
