Product Description

National Geographic StarApp70 – 70mm Refractor Telescope w/ Astronomy APP

Embark on a fascinating adventure through our solar system and beyond with National Geographic’s StarApp70mm telescope. This refractor is great for lunar, planetary and deep sky observing and has a special mount that allows users to attach their smart phone to the telescope and use the ARTelescope App to locate and learn about constellations and planets. As observers move the telescope across the night sky, they will hear facts about the constellations and planets in the app’s database as they come into view. The telescope comes with two interchangeable eyepieces and a 2x Barlow lens to provide a versatile range of magnifications.

Special mount atop telescope tube allows users to attach their device to the telescope and easily locate constellations and planets in the night sky using the ARTelescope AppIn-app encyclopedia provides additional details about planets and constellations70mm aperture is excellent for lunar and planetary observing as well as viewing the brightest Messier objectsComes with two interchangeable Plössl eyepieces and a 2x Barlow lens to provide magnification options of 26.9x, 52x, 72x and 144xIncludes simple mount for smooth movements and a full size tripod with a center accessory trayAdditional adapter helps observers position their own smart device over the eyepiece to capture and share imagesDew shield cover minimizes build-up of moisture and debris on the lens between observing sessions

Possible Objects for Observation

What you can observe at any one time in your telescope depends on several factors beyond aperture and magnification. These factors include location, date, time and sky conditions. The following are all objects that can be seen with the unaided eye and/or binoculars. Your telescope can enhance views of any of these objects if the observing conditions are right.

The Moon: Diameter: 3,476 km Distance: Approximately 384,401 km

The Moon is the Earth’s only natural satellite, and it is the second brightest object in the sky (after the Sun). Although it is our closest neighbor, a lot of people have never really taken a good long like at the Moon. With your telescope, you should be able to see several interesting lunar features. These include lunar maria, which appear as vast plains, and some of the larger craters. The best views will be found along the terminator, which is the edge where the visible and shadowed portions of the Moon meet. Image credit: Howard Eskildsen

Dumbbell Nebula (M27): Right ascension: 19:59.6 (hours: minutes) Declination: +22:43 (degrees: minutes) Distance: Approximately 1,360 light years

The Dumbbell Nebula was the first planetary nebula ever discovered. It is one of the most popular sights in the Vulpecula constellation. Easy to find with binoculars and amazing in a telescope, the shape of this bright, double-lobed nebula has been compared to a dumbbell, an hourglass or an apple core. Additionally, the white dwarf that lies at the heart of the Dumbbell Nebula is larger than any other star of its kind. Image credit: NASA/JPL-Caltech/Harvard-Smithsonian CfA

Pleiades Star Cluster (M45): Right ascension: 03: 47.0 (hours: minutes) Declination: +24: 07 (degrees: minutes) Distance: Approximately 444 light years

The Pleiades Star Cluster is a group of brilliant blue stars located in the Taurus Constellation. Also known as Messier 45 or “Seven Sisters”, this open star cluster consists of more than 1,000 confirmed stars, although an average of only six are visible to the unaided eye. With your telescope, you can quickly reveal some of the more elusive members of this legendary and beautiful cluster. Image credit: NASA/JPL-Caltech/UCLA

Orion Nebula (M42): Right ascension: 05: 35.4 (hours: minutes) Declination: -05: 27 (degrees: minutes) Distance: Approximately 1,344 light years

The Orion Nebula is a vast star-forming region located in the “sword” branching off of the famous Orion’s Belt. Also known as Messier 42, this diffuse nebula is bright enough to see with the unaided eye — although it will only appear as a slightly foggy star. However, with your telescope, you can see many of the beautiful details, such as the billowing clouds of gas and dust where new stars are being born. Image credit: NASA, ESA, M.

GENEROUS 70mm APERTURE: The large aperture makes this telescope excellent for lunar and planetary observing as well as viewing the brightest deep space Messier objects. The coated objective lens transmits light effectively for clear, bright images.
EASY TO ASSEMBLY AND USE: Comes with a detailed user manual with clear, concise instructions for set up and a detailed “Using Your Telescope” section including diagrams and tips to start observing.
ASTRONOMY APP AND SMARTPHONE ADAPTER: Comes with a encyclopedic astronomy app for smart phones that names and outlines constellations in the viewing area as you move the telescope across the night sky. You can take a photo using the app that will superimpose the constellation information from the ap onto the night sky. Also, using the included smartphone adapter, you can take a picture through the telescope to share with friends and family.
QUALITY ASSURED: Manufactured by Bresser and licensed by National Geographic, you can be assured of quality construction and support after the sale.
