How An Atmospheric Dispersion Corrector Works Over the past few years, there has been a revolution in planetary imaging among amateur astronomers. CCD sensors with high sensitivity have made it possible to rapidly obtain large numbers of short-exposure images of the planets. This coupled with powerful computers has allowed amateur […]
Polar Alignment Tip to Make Polar Alignment a Smooth Process This Astro Tip was snagged as one of many great ideas shared by Astronomy Technology Today reader Paul Chasse. It focuses on helping to make polar alignment a smooth process. Pay attention, because this may save you some time and […]
Gondwana Telescopes Marana 12 Telescope Review I ponder this old chestnut of wisdom as I survey my slowly swelling mouth in the mirror. There are two distinct divots in my fattening, bloodied top lip – courtesy of my front teeth – and while shielded from view by an equally […]

He has an MS degree in Computer Science and 35 years of experience in electronics engineering, specializing in image processing. The […]
Losmandy’s venerable GM8, GM11 and HGM Titan mounts are mainstays of amateur astronomy, and now the Losmondy G8, Gll and HGM Titan RA and Dec assemblies are now offered as independent components, allowing you to match, for example, a GM8 Dec assembly to a GM11 RA assembly, or a GM11 […]
If you’ve been involved in amateur astronomy long enough, you’ve seen it happen: A telescope owner is assembling or disassembling his or her mount and telescope and thinks the scope’s dovetail is secure in the mount’s saddle, only to experience the horror of the scope falling to the ground, or […]
The Great Solar Eclipse of 2017 is one of the most anticipated astronomical events in recent memory. For the editors and staff of Astronomy Technology Today, the event has provided the opportunity to focus each magazine issue leading up to the event on solar products, services and techniques. We recently […]
AstroCamp Science & Adventure Summer Camps offer a STEM program for boys and girls ages 8-17 that allows campers to deepen their science understanding by participating in space explorations, learning in state-of-the-art science labs, building and launching rockets, and using a large array of telescopes to explore the night skies. […]
The Solar Eclipse Timer app will put you front and center of the Great American Solar Eclipse 2017 which will cross the United States on August 21, 2017. The app calculates what you can see from the eclipse from any spot in the eclipse’s path with just a two-tap set […]
Explore Scientific ES 80 ED Triplet APO Review Explore Scientific is known for refracting telescopes, quality eyepieces, the David H. Levy Comet Hunter , a Maksutov-Newtonian telescope and Twilight I and II alt-azimuth mounts. I own a Twilight II mount and enjoy using it with various small refractors and […]
Sharing the Cost of Remote Observatory Rental Remote imaging promises virtually hundreds of clear nights a year under dark skies and excellent seeing – conditions that allow very deep images. Most of us look into imaging at a remote site, take one look at the costs, and assume it cannot […]
Astro Hutech Hinode for Solar Imaging In the realm of astronomy, there are several “first” that are sure to leave people speechless. Being involved in astronomy outreach, I can tell you that one of the most notable ones is the first time a viewer sees the rings of Saturn. Words […]
