What is Skywatcher Black Diamond?
Sky-Watcher Global The Black Diamond 80 ED is a modestly wide-field telescope offering bright, wide swaths of sky in a single view. It is well suited for wide-field astronomical observation of prominent nebulae, star clusters, and galaxies from a dark-sky location, or can be used as an astrograph for sky photography.
What is a 80mm refractor telescope?
The ED80 refractor telescope sports a multi-coated 80mm aperture objective lens doublet, one element of which is crafted from Extra-Low Dispersion, or “ED” optical glass. This high-grade glass greatly reduces the chromatic aberration inherent in standard achromatic refractor telescopes.
What does OTAW mean telescope?
Optical Tube Assembly (OTA) The main tube of a telescope including the primary mirror or objective lens, focuser, and finder scope. The optical tube assembly does not include a mount or tripod.
Is 80 mm telescope good?
If you’re looking for a telescope that will give you a great view of the moon and planets, even on nights of poor seeing, an 80mm refractor telescope is a great option…. It’s not a huge aperture telescope, but it’s a good choice for anyone who wants to see more than the moon and planets.
What can I see with a 80mm telescope?
The 80mm objective lens and short 400mm (f/5.0) focal length are perfect for taking in wide swaths of the heavens, making it ideal for larger deep-sky objects. You’ll see spectacular star clusters, wispy nebulas, and expansive galaxies with this telescope, but it also excels at viewing objects in our solar system.
What focal ratio is good for planets?
Focal Ratio – Faster, Brighter, Smaller A long focal ratio implies higher magnification and narrower field of view with a given eyepiece, which is great for observing the moon and planets and double stars. For such objects, a focal ratio of f/10 or more is ideal.
Is 80 mm refractor telescope good?
How does the alt azimuth mount differ from the equatorial mount?
Alt-azimuth mounts track in iterative up/down – left/right movements. Equatorial mounts are essentially alt-azimuth mounts but tilted at an angle based on your GPS longitude. This also corresponds to the altitude at which the north star (Polaris) sits in your sky.
What is the Sky-Watcher 80/600 EvoStar Ed doublet Ota?
The Sky-Watcher 80/600 Evostar ED Doublet OTA is a refractor telescope that well designed for wide-field astronomical observation of prominent nebulae, star clusters, and galaxies from a dark-sky location. Come with focal ratio f/7.5, it can be used as an astrograph for sky photography or telephoto lens.
What makes the Skywatcher Black Diamond Black Diamond ED80 so special?
An anti-reflection metallic coatings which ensure optimum light-transmission approaching 99.5%. The objective lens cell of this SkyWatcher Black Diamond ED80 is light-baffled to reduce stray & unfocused light to insure optimum contrast.
What can the Black Diamond 80 Ed be used for?
It is well suited for wide-field astronomical observation of prominent nebulae, star clusters, and galaxies from a dark-sky location, or can be used as an astrograph for sky photography. The Black Diamond 80 ED is a modestly wide-field telescope offering bright, wide swaths of sky in a single view.
What does Ota stand for in Skywatcher?
SkyWatcher Black Diamond 80/600 ED Doublet Refractor (OTA) The SkyWatcher Black Diamond ED80 is a refractor telescope that well designed for wide-field astronomical observation of prominent nebulae, star clusters, and galaxies from a dark-sky location.
