The year 2020 holds some big product anniversaries for our company. Tele Vue was founded in 1977 by Al Nagler, originally to sell his television projection lenses (hence the name “Tele Vue” to match the abbreviation “TV” — read “Tele Vue: What’s in a Name?” blog post). In 1980 Al introduced Tele Vue to the amateur astronomy market with its inaugural range of four Plössl eyepieces (26mm, 17mm, 10.4mm, and 7.4mm). Additional models followed over the years until the final five focal lengths were released 25-years ago (1995).
Nagler – 40 years
With the positive reception of the Plössl eyepieces (hailed as “the sharpest I’ve ever used” by Astronomy editor Richard Berry) Al Nagler had the confidence to then bring to market his ground-breaking 82° Nagler eyepiece. This eyepiece used principles from Al’s work a decade earlier on an optical probe for an aircraft landing simulator. So began the era of “spacewalk” viewing forty years ago. (See slide show in “I Thank My Lucky Stars!” blog post.)
Just in time for the holidays: the Tele Vue Apollo 11mm collectible eyepiece is now shipping!
When you receive your Tele Vue Apollo 11mm eyepiece, please post a photo on social media and tag it:
In recognition of the 50th anniversary of the Apollo 11 Moon landing, Tele Vue is proud to celebrate our founder’s contribution to the greater effort that made the mission possible and ultimately successful. The special, limited edition commemorative Tele Vue Apollo 11mm eyepiece pays tribute to the simulator program that was invaluable to astronaut training and to the direct influence it had on the eyepieces we enjoy today. We have developed unique packaging for the Apollo 11 eyepiece that consists of a high quality, presentation box with a message from Al and a serialized commemorative medallion matching the serialized eyepiece.
As we close-out the year, we’d like to update you on what is going on “behind the scenes” at Tele Vue! From the arrival of the Apollo 11mm eyepieces to the ongoing GoodBuy 2019 Sale, and answering your questions in between, our employees in upstate New York are somewhat like Santa’s “elves” this time of year!
“40 Hours of Terror” is how a Washington Post correspondent described Hurricane Dorian’s impact on the Bahamas this past September. The category 5 storm lashed at the islands with 185-mph (295-km/h) winds (tying a record) and relentlessly drove water and debris over land to cause loss of life and $7-billion in property damage. So thorough was the devastation, that recovery efforts are expected to take many years.
Images from the 2019 Mercury Transit made with Tele Vue gear have now been posted to social media. We present here the best (with permission) and note that Tele Vue Powermate™ amplifiers “shone” in the creation of most. Not only does Powermate™ help fast, modern scopes achieve a focal length suitable for imaging the tiny planet, but some high-end, drawtube-side, narrow-band filters requires a Powermate’s telecentric operation to create parallel rays for best image contrast. (See Daystar application of Rear-Mounted Filter page).
From 11 November 2019 to 27 December 2019 enjoy 10% savings on all Tele Vue eyepieces*, Barlows, Powermates, and 2″ Paracorr Type-2! Also, receive a FREE Nagler Type-6 or DeLite eyepiece with purchase of Tele Vue telescope with matching accessory package. Please read details below.
It was Johannes Kepler (of “Kepler’s Laws of Planetary Motion” fame) that first predicted transits of Mercury over the face of the Sun. He predicted the May 1607 event and November 1631 event. However, nobody knew how big (or small) Mercury would appear against the Sun, leading Kepler to misidentify a sunspot as the planet when he observed the the first prediction. Kepler was deceased by the time of the second event, but a French astronomer confirmed the transit took place.
The next Mercury Transit is set for 4-days from now: November 11, 2019. This blog will tell you all you need to know to view and image this rare sight!
Anis Abdul’s composite image of Uranus and moons is from the October 2017 opposition and was posted to his Facebook page. The imaging gear used was a Celestron Edge 11 telescope, riding on on AP900 mount, that was “amplified” with our Tele Vue 2.5x Powermate to achieve 7,000 mm focal length. Imaging was done with a ZWO ASI224MC color camera . The best 50% of frames from 20-minutes of video were processed for the image. Software used was Pixinsight and Registax.
“One of the closer moon (Miranda) is actually visible in my stacks but is lost in the planet glow ,” says Anis.
The “ice giant” planet Uranus was in opposition on October 28th. That means that the Sun, Earth, and Uranus all lined up together at an instant in time on that date. Uranus is on the same side of the Sun as the Earth, so the planet was closest to Earth and brightest for the year and in the sky all night long. If you missed it: don’t worry. The slow-moving planet will remain at least 3.7″ of arc in diameter and at magnitude 5.7 for the next month.
A late-summer / early-fall tradition, the Central Pennsylvania Observers’ (CPO) Black Forest Star Party was held at Cherry Springs State Park in Pennsylvania last weekend. This is a special place for observers in the northeast: designated a Dark Sky Park by both the state and the International Dark Sky Association, it is one of the darkest areas in the state. It has a large designated Astronomy Observing Field 2,300 feet above sea level where the state has installed concrete observing pads, domes, electricity, and WiFi for observers.
Al spent some time showing people the views through a TNVC PVS-14 Night Vision monocular connected to John Vogt’s amazing 32-inch scope. Al estimates that the views of the Helix Nebula through this setup were like those from a 90 inch scope! Carl Lancaster captured M17 and M27 through this setup by putting an iPhone up to the eyepiece and snapping off pictures.
