NP101is: Imaging the Skies Over Louisiana

The Lagoon Nebula (also M8, and NGC 6523) in the constellation Sagittarius is well-known to amateur astronomers. It is a giant star forming region with an open cluster of stars embedded within (visible on the right side of the image). A giant O-type star pumps out massive amounts of ultraviolet light that energizes the gasses in the nebula and cause them to emit light in their distinctive characteristic colors. By taking images through emission line filters, astronomers can see what elements are contained in the nebula. In this image made with Hydrogen-alpha, Sulfur II, and Oxygen III filters, the bluish glow of ionized Oxygen predominates in the center of the nebula.

Tele Vue and the Moon Men from Philly!

We got a call into the office a while back from the “Philly Moon Men.” The caller identified himself as one of “Moon Men.” He told us of their astronomy outreach project in the city of Philadelphia and would we like to be part of it in any way? Al has been a sidewalk astronomer since a teenager and David was more than happy to listen to their ideas and help guide them towards their goal.  They’ve setup scopes on street corners and vacant lots in the inner-city to show people that they live in a Universe. Because every human being that has ever lived has looked at the same Moon, all humanity is connected by the sight of this celestial object.

We were intrigued by their youthful enthusiasm and dedication to using telescopes as a means of bridging socioeconomic gaps.  We invited them to meet us at the Northeast Astronomy Forum at the beginning of April to make connections with other outreach groups and see how other ideas meshed with their own. Two smartly dressed Moon Men showed up and told us more about their adventure with astronomy and how the NEAF experience was invaluable to furthering their understanding of what’s going on in the outreach community.  Frankly, they were quite surprised at how much was already going on!

Tele Vue’s NP127fli in the Land Down Under!

Large Magellanic Cloud/Tarantula Nebula Widefield by AstroBin user Jarrett Trezzo. All rights reserved. This field shows the Tarantula Nebula (bottom-half reddish nebulae) and a section of the Large Magellanic Cloud (LMC). TeleVue NP127fli with FLI ProLine 16803 camera and Astrodon LRGB filters exposed for 6×300″ (bin 1×1) for luminance and 12×150″ (bin 2×2: Red, Green, & Blue: 4 x 150 each) for color. Total integration time was 1.0 hour. All riding on 10Micron 2000 HPS equatorial mount. From Siding Spring, NSW, Australia.

Our blog often profiles an imager employing one of our scopes.  But this week we have a twist: we profile a single Tele Vue scope used by many imagers!  It all began when we started spotting deep space images, posted on-line, created with our  Tele Vue-NP127fli  dedicated astrograph. All the images were made from Australia by different people. It turns out this scope is part of iTelescope.net’s collection of robotic scopes at Siding Spring Observatory. Labeled as the “T9” scope, it does wide-field imaging with the FLI ProLine PL16803 (52mm diagonal CCD) camera.

Look Back: NEAIC, NEAF, & Apollo 11mm

In case you missed it: our flickr album has images from the Apollo 11mm “Magic Moment” and the Northeast Astronomy Forum 2019.
Just two weeks ago and a day ago we were  scrambling to get the banner and handout literature ready for the Tele Vue Apollo 11mm eyepiece reveal at the Northeast Astronomy Forum (NEAF) show. At the same time, our imaging equipment was being gathered, transported, and setup for the Northeast Astro-Imaging Conference (NEAIC) that would begin the next day. Additionally, products not being shown at NEAIC were cleaned and collected for the NEAF show commencing that weekend. Plus, we’d inspected and boxed hundreds of eyepieces, Barlows, Powermates, and Paracorrs for our Cosmetic Sale at NEAF. All NEAF items had to be transported and setup on Friday afternoon at Rockland Community College, along with the NEAIC gear brought over when that show ended. We had our work cut out for us that week!

Tele Vue’s Secret Launch: Apollo 11mm Eyepiece!

Tele Vue President David Nagler grinning  ear-to-ear over the Apollo 11 eyepiece.
A package arrived at Tele Vue’s door on the Monday before the 2019 Northeast Astronomy Forum (NEAF). It was quickly ushered into the corner office where a small group gathered around the parcel. When opened, three black boxes were withdrawn. For the first time, after many months of development in secret, each black box was opened by a member of the design team. At Tele Vue, we call these internal product reveals a “magic moment” —  when  fresh prototypes are unboxed in the office for “first light.” This was a “magic moment” unlike any other; one 50-years in the making. The Apollo 11mm commemorative eyepiece had landed!

Tele Vue at NEAIC!

Updated 4/4/2019 1:23 PM

NASA astronaut Donald Pettit (Space Shuttle / ISS / Spacewalker) speaking with Tele Vue Optics President David Nagler today at the 2019 Northeast Astro Imaging Conference (NEAIC). He is at the conference to discuss imaging from the ISS.

The Northeast Astro-Imaging Conference (NEAIC) kicks off today and Tele Vue is there. NEAIC runs April 4 & 5, 2019 and is located at the Crowne Plaza Conference Center, Suffern, New York — only 30 miles north of Manhattan.

Keep Calm …. !

April 6 & 7, 2019
SUNY Rockland Community College
Suffern, NY
 
Here at Tele Vue headquarters, eyepieces, scopes, accessories, tools, literature, and banners are coming off the shelves and being boxed up. It looks like we’re moving. Are we? No, it’s just that we’re getting ready for the annual Northeast Astronomy Forum (NEAF) in Suffern, NY. All the aforementioned activity here is because we bring everything to this yearly event. After all, NEAF is the billed as the “World’s Largest Astronomy & Space Expo.” Over the course of two days, thousands of visitors will descend on the Field House at SUNY Rockland Community College (RCC) in Suffern,  to see, handle, and maybe buy just about every astronomical product on the market today — all under one roof.

Of the Moon and Messier Marathon

Composite image of Messier Marathon Checklist over Messier Object images. Messier objects by Michael A. PhillipsCC BY 4.0, Link

Beginning amateur astronomers soon encounter the term “Messier objects.” They learn that this is a list of objects outside our Solar System that are visible through small telescopes. This list was originally compiled by Charles Messier, in the 18th century, from his observations and those of contributors. The catalog has been updated over time, as recently as the mid-20th century, to 110 objects in total.

NP127is: Imaging the Skies Over Taos, NM

NGC7000 North America Nebula-NP127is by AstroBin user Jerry Macon. All rights reserved. Used by permission. Tele Vue-NP127is flat-field, APO refractor with ZWO ASI128MC Pro full-frame color CMOS camera with 2″ Astronomik L-2 UV-IR Block filter. Exposure 59 x 240″ for a total of 3.9-hours. Mount:Paramount MEII with Absolute Encoders. Software:Sequence Generator Pro, PixInsight 1.8.

We’ve noticed some nice full-color and RGB  deep-sky images made by Jerry Macon using our Tele Vue-NP127is telescope. They’re all taken from his private Dark Star Observatory in Taos, New Mexico.  His image of the expansive North America Nebula (NGC 7000 – above) displays how the deep red light of Hydrogen-α dominates this emission nebula (an  ionized cloud of hydrogen gas about 3° across). A feature of this nebula is the “Cygnus Wall” section at the bottom, that includes “Mexico” and “Central America.” This feature is a dense star-forming region of dust and gas that is often imaged alone without the rest of the nebula.
