We found unique takes on familiar deep-sky objects on David Augros’ AstroBin account. They were taken with our Tele Vue-NP101is refractor (photo/visual, 101mm, f/5.4 APO) using our Large Field Corrector (LCL-1069) and modified Canon EOS 6D DSLR.
We asked David how he got involved in astro-imaging and why he choose this scope. He told us in his own words.
On the 23rd, the “ice giant” Uranus will be visible all night, as it rises when the sun sets (hence it is opposite the sun). It will also be at its largest for the year: a diminutive 3.73″ of arc. Due to its distance and close-to-circular orbit, Uranus doesn’t vary that much in brightness over time. It will reach magnitude 5.7 from mid-October through early November before slightly fading to magnitude 5.9 in late March 2019. This makes it a naked-eye target in dark skies and easy to locate in a binocular or finderscope.
We’ve noticed a proliferation of close-up plane images on Instagram made using Tele Vue Powermate™ image amplifiers. What is amazing about these images? They are taken from the ground with the plane at jet-aircraft cruising altitude. This is the imaging side of the hobby of “plane spotting.” It is sort of like bird watching — but the “bird” is much bigger and potentially much further away: in the stratosphere!
While imaging a bird can be serendipitous, the modern plane spotter has the advantage of free online flight-tracking software, such as FlightRadar 24 and FlightAware, to predict what aircraft are approaching their location. Aircraft identification, route, speed, altitude, and heading are just a click away. This software has also made its way to the ubiquitous smartphone. Thus, unlike birding, plane spotters can anticipate targets to observe in advance. This gives the spotter time to prepare for encounters with common and rare aircraft — like the Antonov An-225.
Autumn Starfest Review
Last SaturNday, Al Nagler began his talk at the Amateur Astronomers Association (AAA) of New York’s Autumn Starfest in Central Park by reminding the audience he “grew up in this area” and saying it was “magical to be here.” Standing next to a 133” diagonal screen, he proceeded to explain how a city kid developed a love for astronomy that began at the old Hayden Planetarium – located just a 15-minute walk from where he was speaking. That passion for astronomy led to a job creating optical systems for the Apollo’s lunar landing simulator, which ultimately served as the inspiration to develop optical products for amateur astronomers.
Afterwards, Al had a Tele Vue-NP101is on a Gibraltar HD4 mount setup for people to view through using various Ethos, DeLite, and Nagler eyepieces. Due to the clouds, deep-space objects were hit and miss. When the clouds were dense enough to obscure the Moon and the bright planets, views of the surrounding buildings were shown instead. Said Al afterwards:
Tele Vue Founder and CEO Al Nagler will be the lead-off speaker, Saturday evening, at this year’s Autumn Starfest in Central Park, New York. This free, annual event, hosted by the Amateur Astronomers Association (AAA) of New York, will feature speakers (with a 133” diagonal screen for people in the field), telescope viewing courtesy of the AAA members, free raffles, and gift bags for the first 250 entrants. Views through the telescopes will include “Jupiter, dwarf planet Ceres, Saturn, asteroid Vesta, Mars, and nearly Full Moon. Beyond the solar system, bright globular clusters, open clusters, and multiple stars can be observed”.
Tele Vue-60: Compact Travel Scope with Imaging Capability
This week we turn our attention to the capabilities of our smallest telescope: the Tele Vue-60. This 60-mm aperture, f/6, APO refractor offers users a maximum 4.3° visual field and a potential of reaching 150x —all this in a package just 10″ long and a svelte 3-lbs. Due to its diminutive size, it is easy to overlook this instrument when shopping for a quality APO travel-scope. But, many users have been pleasantly surprised at the capabilities of this small refractor.
We received a nice account from Fred Miller of Portland, TX, relating his experience at this year’s Texas Star Party with a Tactical Night Vision Company (TNVC) night-vision monocular outfitted with our astronomy adapters. We called him on the phone to discuss putting his report on our blog . He agreed and added that the feel of sweeping the sky with night-vision setup was that of the proverbial “kid in a candy store”.
Mars will exceed 24-arc-sec in diameter between July 23rd and August 9th, 2018. This is 97 percent of the maximum of 25.13-arc-sec diameter attained during the last of the ‘favorable’ apparitions, which occurred in 2003.Association of Lunar and Planetary Observers
This year we received a phone call from Jeff Bennett with some questions about his new TV-NP127is scope. He’d only been using it since the fall of 2017 but was very enthusiastic and told us he’d tried other scopes, but the NP127is was the best he’d ever used. We viewed his astrobin.com page and we were impressed with his initial results. So, we asked him to tell us why he chose the NP127is for astro imaging and he told us in his own words.
