If you follow the Tele Vue re-post (#RPTVO) hashtag on Instagram you’ll find many stunning images made with Tele Vue gear. That’s how we found Jun Luo (aka: xchaos360) and his Tele Vue-NP127is images. He’s relatively new to astrophotography and has produced some very nice images. We had a conversation with Jun about his use of Tele Vue gear for imaging and what follows is what he told us.
Paul Andrew has been an amateur astronomer since the age of 11. He is the founder and Honorable President of the South East Kent Astronomical Society in the UK. He’s had a number of his astrophotographs published — in particular, his solar images — in national newspapers and on websites as far afield as Russia. He’s been short-listed for the prestigious Insight Astronomy Photographer of the Year competition four times now. We’ve noted his high-quality solar images and discovered that many were made with our Tele Vue 2.5x Powermate in the imaging train. So, we present a selection of his work in this week’s blog.
Night Vision astronomy continues to expand with more and more amateurs buying military-grade night vision gear. As Gavin Orpin told us in a guest blog post last year, night vision “has given me a completely new aspect of the hobby to explore.” He’s able to observe Deep Sky Objects through his portable Tele Vue-85 that would have been impossible to see otherwise from his home near central London.
We’ve taken advantage of the full-field capability of our 55mm Plössl by introducing a night vision specific converter lens that extends its focal length to 67mm; thereby reducing the eyepiece’s apparent field of view from 50° to 40° to exactly match the field of view of the PVS-14 objective. That’s a 20% increase in true field-of-view seen with a simple screw-in accessory lens!
Starbeam has long been the highest quality, unit-power finder companion for the amateur astronomer. Looking through its 40mm glass lens you see an unamplified, natural sky background with a 10 arc-minute (1/3 Moon diameter) collimated “red-star” superimposed over it. Alignment adjustment is built in to Starbeam so no tools are required to align it with your scope. For high-angle targets, the unique flip mirror feature saves your knees and neck by letting you look down into the mirror to see the reflection of the sky. This elegantly designed finder comes in three mounting versions for Tele Vue rings, Newtonian scopes, and Schmidt–Cassegrain scopes.
While Tele Vue Optics Inc. is CLOSED due to Covid-19 we’ll post items of interest to our readers on the blog from time-to-time.
A Note from Al Nagler
I’d like to thank Susan Sherwood, director of TechWorks! (www.ctandi.org) for celebrating the 50th anniversary of the safe return of the Apollo 13 crew.
I’m honored to be a part of the team she assembled to help restore the Lem simulator optics, which I designed at Farrand Optical Company, a sub-contractor to Grumman, working with GP-Link.
The simulators were used to train all the Apollo mission astronauts for moon landing — and played an important role in saving the Apollo 13 astronauts — as told in the following narratives.
The greatest untold story of the Apollo 13 mission is that of the spacecraft simulators.Gerald Griffin, Apollo Mission Control Flight Director
Apollo 13 was the third attempt to land astronauts on the Moon. The landing site chosen was north of Fra Mauro crater, on the opposite shore of Mare Cognitum from where Apollo 12 had landed five months earlier. It may be hard to believe now, but no major television network covered the launch of the 363 ft (110.6 m) tall Saturn V rocket as it slowly lifted off Launch Pad 39A at the Kennedy Space Center on April 11, 1970 at 2:13 p.m. EST. Trips to the Moon had quickly become blasé in the public imagination and only the Center staff, spectators, and people living on the Space Coast turned their heads to follow the crew as they began their journey into space on a tail of flame.
The initial part of the mission was indeed uneventful for Commander Jim Lovell, command module pilot Jack Swigert and lunar module pilot Fred Haise. But at about 55 hours, 55 minutes into the mission, Swigert calmly radioed flight control in Houston, Texas with the famous words: “Okay, Houston, we’ve had a problem here.” The crew had felt a loud bang and were losing electrical power. His understated tone didn’t trigger any urgency until Commander Lovell looked out the window and told Houston the ominous news. “It looks to me, looking out the hatch, that we are venting something.” He repeated this for emphasis, stumbling over his words: “We are venting something out into the — into space.” It was late in the evening of April 13, 1970 when the blasé faded and the news networks began to pay attention to the drama 210,000 miles (330,000 km) from Earth.
We all find ourselves in an extraordinary circumstance, coming together to ensure the health and safety of our families, neighbors, and communities as the COVID-19 pandemic continues to escalate. This unprecedented situation has no manual or guidebook; we are all in it together, figuring it out and making decisions on a day-by-day or even hour-by-hour basis. The health and safety of our employees and customers are our top priorities.
To support efforts under way to slow the spread of the virus, and to comply with the current Executive Orders handed down by New York State, Tele Vue will be CLOSED until such orders are lifted. The closure may lead to temporary shortages of Tele Vue products at your dealer. When it is safe to resume work, we will restart deliveries of the products that bring the wonders of nature closer and sharper than you’ve ever imagined.
Until then, our hearts go out to everyone impacted by COVID-19, including those diagnosed by the virus, all of the caregivers at home and in healthcare, and those whose job or school has been affected. We are all living through a time of great uncertainty when we do not know exactly what will come in the weeks and months ahead. There is no doubt that we are in uncharted territory, but of this we are certain: we will get through this, stronger and more resilient than ever. We thank you for your support and hope you stay well, stay safe and take care of one another.

Getting out in the desert for astrophotography is definitely sheltering in space.
We encountered the above phrase, this week, in the caption of an image of the Christmas Tree Nebula, made with our Tele Vue-85 APO refractor. We felt it apropos for our hobby as it succinctly conjures the connection between amateur astronomy and our current moment in world history.
The image was posted to Flickr by Los Angeles based amateur Bill Allen. So we decided to ask Bill about his journey into astronomy and astrophotography and showcase some of his images in this week’s blog.
The Messier Marathon is a northern latitude event that takes place on a night in March or early-April. This is a time when all 110 Messier objects are visible from the northern hemisphere. (See our 2018 blog post on how this list came about). Singularly and in groups, amateur astronomers stay up all night in a “marathon” session to try to view them all! To be a successful “marathoner,” you need to pick the right evening, have clear weather, good site selection, and a manually driven observing setup capable of wide fields of view.
This week we look back at the most popular blog posts of 2019 and give you a peek at one of the new products we’ll debut in 2020.
2019: Blog in Review
Our blog keeps rolling along! Published continuously since January 2017, our subscribed audience continues to grow, and increased by 50% last year. Thanks, everyone! The following are highlights from some of the 49 blog posts that we published last year. All these were in the top-10 by pageviews.
By far our most popular posting was “Tele Vue’s Secret Launch: Apollo 11mm Eyepiece!” that chronicled the behind-the-scenes development of the Apollo 11mm eyepiece and its last-minute introduction at the Northeast Astronomy Forum (NEAF) 2019. We explain what makes this eyepiece special to us, the “magic moment” reveal, and the reaction at NEAF. There are still a few of these limited edition eyepieces available for collecting, gifting, or just viewing through. Contact your dealer if interested.
A must-read article for anyone considering night vision astronomy, “Night Vision in the UK: Seize the Night!“, by guest blogger Gavin Orpin, was high on the top-10 list. Gavin says that night vision “has given me a completely new aspect of the hobby to explore.” He explains his use of night vision gear for hand-held and telescopic observing. This includes the use of 6nm Hα (for nebulae) and 685nm infrared (for galaxies and cluster) filters and adapters for simple imaging through the night vision monocular on and off the scope. We also delve into how the PVS-14 night vision monocular got its name. The blog came about as a result of a discussion between Gavin and Tele Vue President David Nagler at the AstroFest 2019 show in London.
Travel far among the stars, Gene. We’ve got your cap.
Dear Al Nagler:
You may recall, I met you in September 2019 at the New Jersey Astronomical Association (NJAA) Open House in High Bridge, New Jersey. There, I had you sign a Tele Vue baseball cap for me. That was a very special moment for me, and for the cap’s former owner, who would have been thrilled to meet you. You see, the cap has a particularly interesting history.
The cap belonged to my dear friend and astronomy mentor, Gene Ramsey, who had passed away just three years before. Gene loved astronomy, acquiring his first telescope as a young man. He continued the hobby through his years in the Air Force, where he served until 1962. Upon retiring in the 1990’s, Gene joined the Amateur Astronomers Association of Princeton (AAAP). It is there where my wife, Jennifer, and I meet Gene in 2012.
