We were struck by the neon-like colors produced by Murray Parkinson’s imaging through our Tele Vue-NP127is APO Refractor using different combinations of Hydrogen-alpha (Hα), doubly ionized oxygen (OIII), and ionized sulfur (SII) filters. His Porpoise Nebula image below looks like it is leaping out of the page! Others agree: he provided the cover and inside cover spread images for Nightfall October 2017 (a journal of astronomy in South Africa). He tells us “I love my two Tele Vue refractors. Only wish you made a 12-inch refractor … .” This week’s guest blog post is a gallery of his work from suburban Sydney, Australia.
“When I became interested in astrophotography, I quickly learned that the quality of the optics was crucial to achieving high-quality results. Only the very finest telescope designs can deliver round, pinpoint stars across the entire frame. I chose the Tele Vue-NP127is partly because of the reputation of Al Nagler and partly because of trust in products made in the USA. I also had a lot of trust in the salesperson who looked after me at BINTEL in Sydney. He always gave excellent advice on what to buy.
“Without a doubt, the versatility of the Tele Vue-NP127is stands out in my mind. The telescope delivers true astrograph performance when imaging at multiple focal lengths. It also delivers brilliant views when used visually and is light enough to transport to a dark sky location on a car camping trip. I still love visual observing and appreciate a telescope that can deliver on all accounts.
The Porpoise Nebula in Canis Major
“This faint Oxygen III nebula is catalogued as Sharpless 308 in the constellation of Canis Major and is commonly called the Gourd Nebula, but I am one of those people who see a Porpoise first, or I am fonder of porpoises than gourds anyway. The nebula is classified as a Wolf-Rayet bubble and originates from the star located close to the centre of the frame.
“When I was a young boy in the early 1970s, my stepfather took me to see a movie at a drive-in theater in the country. At the end of the movie, I stepped outside the car and looked up to behold the summer Milky Way overhead. This was the first time I had seen the Milky Way from a dark location and I was overwhelmed with awe. To this day, I still experience awe, swooning at the beauty of a starry night when I am lucky enough to camp somewhere truly dark.
We noticed some great Tele Vue-NP127is images on Instagram tagged with our #RPTVO (repost hashtag). They were all taken by Greg Thompson in Tele Vue’s home region of the Hudson Valley, NY. Due to the weather, one has to be persistent to be an astro-imager in these parts. So, we contacted him and that resulted in this guest blog post in two parts. The first part describes his journey into astrophotography and experience imaging with the Tele Vue-NP127is and the second part is a step-by-step guide for image acquisition and processing.
When I saw the first image of the Orion Nebula on the camera’s LED screen ─ WOW, I was hooked!
As a child, I would always look up at the night sky in hopes of seeing a “shooting star.” I loved the night sky but was never interested in astronomy or cosmology as a young man. I began a photography business in 2011 and had to take early retirement from my day job of 25+ years. My photography led me down many roads, from portraiture and landscapes, birds and wildlife, and many other genres. I had heard of astrophotography but was not interested as I thought it was beyond my reach. Then the television series “How the Universe Works” came to my television in 2016 and could not get enough of it. Soon after, I was browsing a photography forum that I was a member of, and saw some photographs (Deep Sky Objects’s) that a well-known scientist and photometrist had posted using a camera that I already had, and a lens very similar to one of my lenses. That opened my eyes wide and I then began to research everything about astrophotography. Three months later I bought my first camera tracker (Fornax LighTrack II) and accessories to begin my new hobby. That was in the fall of 2016. When I saw the first image of the Orion Nebula on the camera’s LED screen ─ WOW, I was hooked!
This week’s guest blog post is by Luca Marinelli. He images the sky with a Teleskop Service ONTC 10″ Carbon Tube f/4 Newtonian equipped with our Tele Vue Paracorr Type 2 coma corrector.
I have been interested in photography since a very young age. I remember learning to take pictures with my father’s Russian-made Zenit-E 35mm fully-manual SLR (you had to remember to close the iris by hand before shooting to set the desired aperture!) when I was in elementary school. I have pursued nature and adventure photography ever since and some of my images have been published.
We posted some Instagram sketches of the July 2019 Total Solar Eclipse from Chile last month made by Pekka Rautajoki — who traveled all the way from his native Finland to be there. We found a trove of blog-worthy images, he posted on Instagram, made with Tele Vue eyepieces and Tele Vue-85 APO refractor. They encompass a broad range of objects from the northern and southern hemispheres. So, it was only inevitable that we invited him to write a guest blog post based on his exquisite work!
In this guest blog post, Ted Hume describes two telescopes designed and built by Clyde Bone. At first they appear to be “big-Dobs.” However, look close and you’ll note they don’t require “shaky ladders” as the final focus is through Tele Vue telescopes near ground-level. They also serve as their own finders. Read on about these fascinating instruments and how they could be yours!
Clyde M. Bone, Jr. (1928 − 2012) of San Angelo, Texas designed and built two Mersenne telescopes, first a 20-inch and then a 30-inch.
His career included working for the Texas Border Commission in the Big Bend area of Texas, geologist for an oil company ─ who flew a light plane to drilling sites and landed on dirt roads, science teacher at a Texas high school and in the Texas prison system. When he decided to build a Mersenne telescope, he was retired and spent a year studying optics. Then he was ready.
Barry Kawa, a U.S. journalist now living in Japan, wrote a prior blog for us (Does it spark joy?) about the joy of collecting scopes and the task of paring down the collection to what gives him joy. You can read this post as a “part 2” for the phase of life when it’s time to go with just one scope and mount.
This week’s guest blog post is written by Gavin Orpin. The blog came about as a result of a discussion between Gavin and Tele Vue President David Nagler at the recent AstroFest 2019 show held at the Kensington Conference and Events Centre in London.
Coming from the U.K., using night vision for astronomy is very rare due to the cost and difficulty of getting the night vision equipment. I estimate there are only around 6 night vision astro users in the whole of the U.K.. However, I was fortunate in that one of my local astronomy club members is the leading U.K. proponent of night vision astronomy, so I was able to see first-hand this technology in action.
[Night Vision] has given me a completely new aspect of the hobby to explore.
Given the significant light pollution, living near central London does create some big issues for visual astronomy. However, night vision has given me the ability to observe DSOs (Deep Sky Objects) with my Tele Vue-85 APO telescope that I would have no chance with normal glass eyepieces. It has given me a completely new aspect of the hobby to explore — for that I am very grateful to my astro club friend and Tele Vue for making it possible for a U.K. based astronomer. In addition, when I do get the chance to visit a dark site, the night vision works even better and I can see things I never dreamed of when I began observing the stars.

I got started in astronomy in the 1990s while I was still in High School. I spent cold clear winter nights in Northern New York learning the basics together with my father on an 8″ Schmidt Cassegrain. I remember trying to manually guide my first prime focus images of M42 with the 2,000mm focal length SCT, shooting 35mm film in 10°F temperatures. The results were predictably flawed and after I went off to college the scope and gear were put away. I went west after finishing school and my astronomy interest faded away under the light polluted sky of Southern California.

I had never seen pinpoint or round stars — apart from observing our round Sun.
I’m old enough to remember when “pinhole” eyepieces with “soda straw” views defined what a telescope offered to the average amateur astronomer. More than anyone, Al Nagler, and more than any company, Tele Vue, changed that by opening up the sky and making it easier to explore through wider field viewing. Mr. Nagler and his company also showed us that a relatively rich field refractor could not only capably serve as an amateur’s sole telescope: it is the best telescope to own if you’re only having one. We can thank Al Nagler and Tele Vue for laying the foundation for the way visual astronomy is pursued today. Yet despite all that, until I tried a DIOPTRX™ on my 22mm Panoptic last year, I had never seen pinpoint or round stars — apart from observing our round Sun. I’ve been observing the sky through scope optics since 1961, my astigmatism never absent. For people like me, DIOPTRX™ is arguably Tele Vue’s most essential product, because it makes all of Al Nagler’s original work in eyepieces and refractors unmistakably worthwhile to the astigmatic viewer.
