Losmandy G-Series Interchangeable RA and Dec Assemblies Losmandy’s venerable GM8, GM11 and HGM Titan mounts are such mainstays of amateur astronomy, you’d think they would defy fundamental innovation. Nevertheless, the mounts were recently treated to precisely that – indeed, to an enhancement that is so fundamental as to be game-changing. […]
One of the best star parties in the country is coming to the Billy Dodd Memorial Field in Chiefland, Florida, October 22 through the 28th. Better yet, there is no charge to attend, but you will need to apply for an admission ticket and free membership by completing a Chiefland […]
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 […]
We are sad to announce that we have lost a long time astro-product innovator and a close friend of those of us in the magazine. We have been fortunate to work with Howie Glatter since the formation of the magazine over 10 years ago and he was always very kind […]
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 […]
