Celestron Cometron FirstScope 76 Dobson/Newton
- Telescope
- Cometron special edition differs from the standard model by the included viewfinder and the two eyepieces, which provide comparatively low magnifications of 15x and 30x
- ideal for observing extended objects such as comets, star clusters or the Milky Way
- Easy-to-use Newtonian reflector telescope with 76 mm aperture
- Ready for immediate use
- Detailed German instructions - including star charts for every season
Celestron has launched the Cometron series on the occasion of the bright comet ISON, which was visible at the end of 2013. In addition to some new developments, there is also a classic in a new design and with accessories optimized for comet observation: the Cometron FirstScope 76.
The FirstScope 76 was first introduced for the International Year of Astronomy 2009 - 400 years after Galileo first pointed a telescope at the sky. Since then, it has been one of the most popular telescopes for beginners and has opened the door to astronomy for many stargazers. The Cometron special edition differs from the standard model by the included viewfinder and the two eyepieces, which provide comparatively low magnifications of 15x and 30x - making it ideal for observing extended objects such as comets, star clusters or the Milky Way.
A high-quality Newtonian telescope at an incredible price
The Celestron FirstScope is a Newtonian reflector telescope of Dobsonian design. In Newtonian reflector telescopes, a specially ground (primary) mirror collects the light from the celestial bodies and directs it to the eyepiece via a second (secondary) mirror, which magnifies the image. The large diameter of the main mirror of 76mm makes it possible to collect enough light with the FirstScope to even observe some fainter objects such as galaxies and gas nebulae in the night sky. Magnifications of up to around 150x are possible. Even higher magnification is possible with short focal length eyepieces - however, no further details become visible, only the image becomes darker. So don't be fooled by the "optimistic" magnification specifications of comparably sized telescopes.
The focal length is the distance that the light bundled by the telescope mirror travels within the optical tube. Despite its compact design, the Cometron FirstScope 76 has a focal length of 300mm. The telescope's basic equipment includes two eyepieces with 20mm and 10mm focal length, which allow a magnification of 15x and 30x respectively. The eyepieces show a large area of the sky, almost like binoculars - so on the one hand you can observe the extended galaxies and nebulae that are too extended for larger telescopes, on the other hand the large field of view makes it easier to find small and compact star clusters and planets in the first place.
For higher magnification, you can use additional, separately available eyepieces. Many star clusters are then resolved into individual stars, the planets reveal their first structures and the moon craters look impressive. The telescope's eyepiece mount is compatible with the 1.25" eyepieces commonly used in amateur astronomy. A 4mm eyepiece, for example, would provide 75x magnification and clearly show you Saturn's rings, the dance of Jupiter's moons or the moon's craters; star clusters are then also better resolved into individual stars.
The Celestron FirstScope 76 has a stable Dobsonian-style table mount. The complete telescope therefore only needs to be placed on a stable table and you are ready to observe. The telescope can be swiveled to the right, left, up and down in its mount - the rotation of the earth can thus be compensated for completely intuitively, and you can always bring the stars back into the field of view if they move out due to the earth's rotation.
Detailed German instructions - including star charts for every season
The best telescope is useless if you don't know your way around the sky. Instead of the usual short instructions in several languages, the German copies of the Cometron FirstScope 76 come with the detailed, full-color instructions for the FirstScope 76, which not only explain how to use the telescope, but also provide an introduction to astronomy. What can you expect when looking at the planets and how big do they appear in comparison with our moon? You will find the answers in the instructions as well as a small moon atlas and star charts for the whole year. Some of the most beautiful objects to get you started are already marked and described - so you won't be at a loss under the starry sky on your first night without knowing what there is to see. The star charts are designed for the FirstScope and do not contain any targets that are only visible in larger telescopes.
Digiscoping made easy
The two Kellner eyepieces of the Cometron 76 have large eye lenses. This not only provides a comfortable view, but is also practical for photography enthusiasts: you can easily take photos with a compact camera through the eyepiece and capture bright objects such as the moon in the image. Nature photography is also possible in this way. This so-called afocal photography is the easiest introduction to astrophotography and even works with a cell phone camera! Thanks to the large lenses, the image is not shadowed even with somewhat larger digital compact cameras - so there is no round image section, instead the entire camera chip is illuminated.
For best results, the camera should be held as close as possible to the eyepiece. This is particularly convenient with a MicroStage camera mount, with which you can position the camera precisely and also swivel it to the side to look through the eyepiece.
