Celestron PowerTank Lithium LT Battery. Celestron’s PowerTank Lithium LT is their smallest and lightest lithium-ion power pack and is a must-have for powering your telescope and accessories, camping gear, emergency kit, and more anywhere you travel. Stable Power Designed for Telescopes. The Celestron PowerTank Lithium LT is built with Lithium Nickel Manganese Cobalt Oxide [LiNiMnCoO2] or NMC technology, which delivers a steady charge over long periods and requires less maintenance than traditional sealed lead-acid batteries. Unlike other lithium-ion power packs in this price range, the PowerTank Lithium LT was designed for astronomers by astronomers-specifically for the unique needs of computerised telescopes. It is well known that telescope electronics are very sensitive to voltage. Powering a telescope with lower-than-optimal voltage can cause the motors to strain with heavier loads and can even cause the electronics to glitch. The PowerTank Lithium LT uses a built-in voltage regulator to ensure that it delivers at least 11.8 volts for most of the life of the battery, until the battery is depleted and shuts off. You may see competitor batteries claiming that they hold enough watt-hours of electricity to power your telescope for hours. The technology in these batteries was originally developed to power much lower-voltage electronics. Although the voltage actually being delivered starts off at 12V, it diminishes rapidly, impacting your telescope’s performance and becoming functionally useless within about 2-3 hours. Celestron’s telescope engineers worked hand-in-hand with battery suppliers on PowerTank Lithium LT to ensure that it does not experience this dropoff in performance. The built-in voltage regulator ensures a stable 12V output, regardless of the amount of charge left in the battery. This keeps your telescope’s electronics safe and performing their best, so you can focus on astronomy. Battery Capacity 73.3 Wh. Charge Time (from flat) 4 hours. Car Battery Adaptor Port None. Auto Shutoff Threshold Current Less than 250mA for 4 hours. Operating Temperature -40°F – 140°F (-40°C – 60°C). Telescope Power Cord 6.5 ft (2 m) with connector for Celestron telescopes. Strap 2 wide hook & loop strap for attachment to tripod leg. Product Dimensions 190.5mm x 101.6mm x 50.8mm (7.5″ x 4″ x 2). Product Weight 1.4 lbs.

Designed to observe and track near and deep-sky objects with a fast focal ratio for astrophotography/imaging, Celestron’s AstroMaster 130EQ-MD 130mm f/5 Reflector Telescope features a 650mm focal length and an oversized parabolic mirror that produce detailed images of the Moon, clear views of the planets, and the ability to resolve distant objects such as nebulae and galaxies. The scope is outfitted with a 1.25 rack-and-pinion focuser and two eyepieces to get new users started: a 10mm that yields 65x power and a 20mm for a 32.5x magnification. The 20mm eyepiece integrates an erecting system to correct images horizontally and vertically to allow easy terrestrial use. An unmagnified red-dot finder is also included to help set-up, align and navigate easier. Its manual equatorial mount features a variable-speed Right Ascension motor drive system capable of working in both the Northern and Southern hemispheres, with variable speed to accurately track fast-moving objects like the Moon and slower deep-sky objects like galaxies and nebulae. For alignment and easy navigation, dual slow-motion control cables are provided; and clearly visible indicators on the Right Ascension and Declination axes. An adjustable-height aluminum tripod rounds out the rig with a tray for accessories such as eyepieces, filters, and lights. Fast f/5 focal ratio. Highly-reflective aluminum-coated mirrors improve light transmission, color rendition, and contrast. Resolution: 1.07 arcsec, Rayleigh; 0.89 arcsec, Dawes. Secondary mirror obstruction: 31% by diameter, 10% by area. 1.25 rack-and-pinion focuser. Variable-speed Right Ascension motor drive accurately tracks near and deep sky objects, with proper polar alignment. Dual slow-motion control cables enable fine adjustments with reduced vibrations. Altitude adjustment screws locks setting. Etched Right Ascension and Declination scales. Two 2.2 kg counterweights to properly balance OTA and accessories for smooth movement. Dovetail plate enables fast assembly and break-down. 1.25 diameter stainless steel legs. Tray to hold eyepieces, lights, and accessories. Spiked feet add stability on uneven/soft ground. 1.25 diameter barrel. Accepts most 1.25 astronomical filters. 10mm focal length produces 65x. 20mm focal length produces 32.5x. 20mm eyepiece has integrated prism to correct image horizontally and vertically for terrestrial use.

Celestron Astro Fi 130mm f/5 Reflector Telescope. Celestron’s Astro Fi 130mm f/5 Reflector Telescope utilizes an integrated antenna to emit a local WiFi signal so you can control the mount via Android and iOS smartphones and tablets running their free SkyPortal app. Optically, the scope sports a large 130mm aperture and a short 650mm focal length to produce a fast focal ratio that can resolve deep sky objects that smaller refractor-style scopes cannot, such as splitting binary stars or separating star clusters. With highly-reflective aluminum and SiO2 (quartz) mirror coatings, light loss is limited so you can make detailed observations of the Moon, view planets and distant nebulae, and get great wide-field views of the sky for comet watching and asteroid hunting. This complete observation rig includes the optical tube assembly, a motorized mount, an aluminum tripod, two eyepieces, and a red-dot finder. The OTA is mounted on a single-arm motorized alt-az mount. Guiding the mount is the SkyPortal app. Packed with over 120,000 objects it is designed to help users set up quickly and start observing faster. The app offers align aids, can automatically find objects in the night sky; and even offers guided tours of the most interesting objects overhead on any given night. The mount runs on eight user-supplied AA batteries, and the entire rig assembles and breaks down without the need for tools so set up is easy and you can start observing sooner.
