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.
Surfing through the AstroBin site’s collection of user generated astrophotos we were struck at this vivid example of M16 “The Eagle Nebula.” The image has a depth and contrast we’ve never seen before. Created using “Hubble Pallet” filters, the rich blue (Oxygen III) surrounding the “Pillars of Creation” structure is highlighted by the ruddy bland of reds (Sulfur) and greens (Hydrogen-alpha and Nitrogen) in the “folds” of the surrounding dust clouds. The blackness of space at the edge of the dust and gas cloud is preserved against all the colors.
We noticed some unique images on AstroBin.com employing our Tele Vue-NP127is and Tele Vue-85 scopes to simultaneously image the same target. The images from the two scopes were combined to create the final image — with fantastic results! All the image locations are given as “Tom’s Driveway” in Terre Haute, IN. Intrigued, we contacted the imager (“Astrovetteman”) to learn how he settled on this technique for many of his images. So we turn over our blog this week to astrophotographer Tom Peter and his dual-scope driveway setup.
Tele Vue President David Nagler recently received a “first-light” report from the very-first Tele Vue Bandmate Type 2 Nebustar filter owner. He purchased the filter at the Northeast Astronomy Forum (NEAF) this year where the filters were introduced. It turns out the gentleman has a long history with Tele Vue products, is a yearly attendee (like Tele Vue founder Al Nagler) at the Stellafane amateur telescope makers convention — and he even coined the moniker “Uncle Al” while at Stellafane.
