CFF Telescopes Apo Refractor Telescopes Whether you are a resolute visual observer or dedicated astro-imager, refractor telescopes offer unique advantages. But, the physics of light being what they are, no single refractor is best at both pursuits, and given the understandable recent market focus on refractors for astrophotography, those of […]
CelestialChart is a web-based tool for both amateur and professional astronomers. It specializes in doing one thing and doing it very well: Providing accurate, easy-to-read, real-time or scheduled (past or future), location-specific astronomical charts of celestial bodies and constellations. Enter a location by city or latitude and longitude, as well […]
Sky-Watcher’s new Stargate truss-tube Dobsonian telescopes offer serious aperture for those looking to sail farther into the depths of the cosmos in big – and even bigger! – deep-sky-gobbling apertures of 18 and 20 inches. For those stepping up from the 12-inch instruments, the 18-inch Stargate captures more than twice […]
At first blush, the PlaneWave PW1000 may appear simply a scaled-up version of Planewave’s PW-700, but as the side-by-side comparison in Image 3 instantly reveals, the challenges associated with that increase in aperture are substantial. The PlaneWave PW1000 is a complete one-meter observatory-class telescope featuring a direct-drive altitude-azimuth (Alt-Az) mounting […]
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.
