The mounting foot of ScopeStuff’s Cell Phone Mount ($22US) attaches to the Orion/Synta-style telescope finder shoes common on many scopes. The other end securely holds smartphones 2 to 3.5 inches (50.8 to 88.9 mm) wide, which covers most of them, and the sturdy stalk bends for adjustment. The Cell Phone […]
SkySafari LiveSky owner and developer, Simulation Curriculum, calls the app “Professional Telescope Astronomy Software,” and it is surely that. But most who don’t search for it by name will find it in Google’s Play Store or Apple’s App Store with a search for “planetarium app,” and it’s that, too – […]
Yes, yes, we know. When you think Unihedron, you think Unihedron Sky Quality Meter. We do, too. The names Unihedron and the Unihedron Sky Quality Meter have become synonymous with measurement of sky brightness. Indeed, it’s hard to imagine a Sky Quality Meter tool that has had greater impact on […]
The heart of William Optics’ Super ZenithStar 103 f/6.9 imaging APO is a f/6.9 air-spaced FPL53 doublet housed in a CNC-machined ultra-precision lens cell. Add a 0.8x flattener/reducer, and the focal ratio becomes f/5.5. Focus duties are performed by the Zenithstar 103 ultra-robust 2.5-inch, 1:10 dual-speed, rack-and-pinion focuser with […]
