What can I see with a 80mm refractor telescope?
For moon and sun, double stars, deep sky within reach, and casual looks at planets (especially Saturn) an 80mm can do well. The 1.5 arc-second resolution of 80mm scope is respectable, and the doubling of light grasp compared to 60mm is obvious.
What can you see with a refractor telescope?
Refracting Telescopes. Commonly known as refractors, telescopes of this kind are used to examine the visible-light region of the electromagnetic spectrum. Typical uses include viewing the Moon, other objects of the solar system such as Jupiter and Mars, and double stars.
Why are refracting telescopes no longer used?
Limitations of Refracting Telescopes This occurs because as light passes through a lens, different colors are bent through different angles (like in a prism) and brought to a focus at different points. Glass also absorbs most ultraviolet light, and visible light is substantially dimmed as it passes through a lens.
What makes the Omni XLT a good telescope?
Omni XLT series features the stable platform of the CG-4 mount and high quality optics. Using aspheric shaping technology in conjunction with hand-figuring the optics, the Omni XLT presents an image with virtually no spherical aberration. We also added our famous StarBright XLT coating system to further enhance light transmission.
What’s the difference between Celestron Omni XLT 120 and 150?
Although the XLT 120 only has a 120 mm aperture and the XLT 150 has 30 mm more and so is larger and offers more light-grasping capability, the two optical designs are different. Can the Celestron Omni XLT be used for Terrestrial Viewing?
Is the Omni XLT 150 a Newtonian reflector?
Disclosure: This post contains affiliate links and I may earn a small commission if you click through and make a purchase. The Omni XLT 150 is the only Newtonian reflector in the series, so if you’re looking for a refractor, you should check out the Omni XLT 120 instead.
Which is the best Celestron Newtonian reflector telescope?
High-quality optics meet elegant design in Celestron’s bestselling Omni XLT 150 Newtonian Reflector Telescope. The glass for each telescope’s objective lens is individually selected to ensure the best performance.
