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.

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.

Imaging the Skies with the TV-85: Mike Broussard

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.)   Continue reading “Imaging the Skies with the TV-85: Mike Broussard”

Cherry Springs 2017 in Review

Al Nagler at Cherry Springs Star Party 2017.

The ancient Allegheny Plateau formed from a long-ago regional uplift in the Paleozoic Era. Over the eons, rivers and minor waterways eroded the plateau to form mountainous terrain. The plateau arcs from central New York, through the top-half of Pennsylvania, dives though the heartland of Ohio and West Virginia, and terminates in Kentucky. Smack in the middle of this arc is Cherry Springs State Park in Pennsylvania. Continue reading “Cherry Springs 2017 in Review”

Tele Vue TV-NP101is Relativity Experiment Update

TV-85 image of Solar Flare during 2008 eclipse in China by D. di Cicco.

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.

Saturn Opposition: June 15, 2017

Saturn will be visible all night in the sky on the 15th as it rises when the sun sets (hence it is opposite the sun). Now is a good time to revisit an essay I wrote a while back about this visually appealing planet.

It’s Saturnday

I’ve found that first-time views of Saturn through a telescope typically elicit gasps of delight followed by inquisitive questioning.

Saturn’s startling beauty can open the door to wonders and knowledge about the universe that can inspire a love and appreciation of all the arts, sciences, and history.

Understanding something of the vastness and nature of the universe and our unique position as the only species possessing such knowledge suggests we commit to fostering the best in us: love, kindness, respect for learning and for all the amazing life-forms we’re so fortunate to share on this wonderful planet.

So let’s use Saturn as a means to enrich our future and help preserve our earthly paradise.

Spread the word to change Saturday to Saturnday through all media and contacts, in every social venue, to start dialogues that can open the minds and hearts of our earthling friends.  Caring for our precious planet and it’s lucky inhabitants, will make future generations proud of our time here.

Saturnday can change the world with your help !

June 9th: Night of the “Micromoon”

The “supermoon” — a full moon that occurs when the moon is nearest the earth — seems to garner a lot of media attention. Very little scrutiny is paid to the occurrences of “micromoon” — an appellation bestowed when the full moon occurs at the furthest reaches of its orbit. Just Google “supermoon” and you’ll get 10-million results vs. a paltry 45,000 for “micromoon”. But the micromoon offers an interesting contrast to the supermoon.

From his backyard observatory in Bountiful, Utah, in the western foothills of the Wasatch Mountains, Jay Butler images the heavens with his 10″ f/4 fast Newtonian – equipped with a Tele Vue BIG Paracorr Type-2. Despite the poor seeing – from suburban light pollution and strong updrafts from the valley floor – he’s been able to score a medley of celestial clusters, galaxies, and nebulae that cross his sky.  Continue reading “BIG Paracorr User Profile:

Excerpts: Al’s Sidewalk Astronomy Adventures

Here Al has upgraded to a 12″ Newtonian.

My high school years were spent scheming and cutting classes to spend every opportunity to work on my shop project. No tie racks for me. A 200 lb. 8 inch Newtonian with a wooden hexagonal tube and pipe-fitting equatorial mount was MY dream project. Continue reading “Excerpts: Al’s Sidewalk Astronomy Adventures”
