The Astro Fi 130mm Newtonian Telescope is a fully featured telescope that can be controlled with your smart phone or tablet using the free Celestron SkyPortal app. Celestrons SkyPortal app replaces the traditional telescope hand control for a 100% wireless experience. Just hold your smart device up to the night sky. When you find an object youd like to view, tap the screen. Your Astro Fi telescope automatically slews to the object, while the screen displays information about it. The Astro Fi 130mm Newtonian Telescope creates its own wireless connection, so it can communicate with your device even in remote locations where WiFi or cellular networks arent available. Getting ready to observe is quick and painless thanks to Celestrons award winning SkyAlign technology. Center any three bright objects in the eyepiece, and your telescope calculates its position. You can even generate a Sky Tour of all the best celestial objects to view based on your exact time and location.SpecificationsOptical Deisgn Newtownian ReflectorAperture130 mm Focal Length650 mm Focal Ratio5Focal Length of Eyepiece 1 mm 25 mm Magnification of Eyepiece 1 26xFocal Length of Eyepiece 2 mm 10 mm Magnification of Eyepiece 265xFinderscopeStarPointerStar Diagonal 1.25Mount Type Single Fork Arm AltazimuthAccessory TrayIncludes rubberized smartphone or tablet holderTripodAluminumHighest Useful Magnification307xLowest Useful Magnification19xLimiting Stellar Magnitude13.1Resolution Rayleigh1.07 arc seconds arc secondsResolution Dawes0.89 arc seconds arc secondsLight Gathering Power Compared to human eye345xOptical Coatings Aluminum with SiO2Slew SpeedsUp to 3 degsecondTracking RatesSidereal, Solar, and LunarAlignment ProceduresSkyAlign, 3 Star Align, Solar System AlignCommunication Ports Aux port for optional hand controlDatabase Over 120,000 objects including 220 of the best deep sky and solar system objects
