Are explore scientific telescopes any good?
Are explore scientific telescopes any good?
Generally we were very impressed by this instrument, although it’s let down slightly by the focuser and the supplied 25mm eyepiece, which was fairly average. However, it has great light grasp, excellent optics for the money and is capable of delivering some stunning results.
What does APO mean in telescopes?
An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses.
What is triplet APO?
Apochromatic (APO) lenses are designed to bring three wavelengths of light (red, green, and blue) into focus in the same plane. The classic achromatic doublet made from optical crown and flint glasses bring two colors of light to a common focus. …
What can you see with an 80mm refractor?
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.
Where are explore scientific telescopes made?
Springdale, Arkansas
Roberts in 2008. Headquartered in Springdale, Arkansas, the company designs and manufactures telescopes, spotting scopes, binoculars, microscopes and other scientific devices. Products are manufactured in China by JOC and imported.
Why are refractors better for planets?
The relatively small aperture of a refractor therefore often has an advantage over a larger reflector-type scope for this kind of observing, as there is less glare from a larger scope’s brightly lit planetary surfaces to wash out faint detail.
Is a reflector or refractor better?
If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
What is apochromatic telescope?
An apochromatic telescope has a multi-lens setup to eliminate chromatic aberration when stargazing. Red light is focussed further away from the lens. This variance in focal length results in small degradations in image quality. This effect is more prominent when viewing certain objects such as planets.
What is Ed telescope?
ED stands for “extra-low dispersion,” which refers to the composition and optical properties of the glass used for the lenses. ED glass is specially formulated and contains rare-earth compounds that greatly reduce a visual defect called chromatic aberration.
Are refractors good for visual?
A good 80mm refractor, for example, can reveal more lunar detail than you can sketch in a lifetime of observing. For purely visual lunar, planetary, binary and star cluster observing, an altazimuth refractor with manual slow motion controls may be perfectly adequate.
Is the Explore Scientific 80mm apo a triplet telescope?
The Explore Scientific 80mm APO Triplet telescope now comes with a lighter carbon fiber optical tube that is less impacted by temperature locations when compared to a traditional metal tube. A triplet optical design virtually eliminates chromatic aberrations.
What do you need to know about the Explore Scientific ED80?
The model available from Explore Scientific had the specifications I was looking for, at a price I was comfortable with for my newfound hobby. The Explore Scientific ED80 Triplet Apochromatic Refractor. The version I purchased included a hard carrying case, illuminated reticle finderscope, and a diagonal.
Is the scientific ED80 air spaced triplet refractor available?
Explore Scientific ED80 Essential Series Air-Spaced Triplet Refractor is Available for Back-Order Purchase or Layaway
What does the Explore Scientific 80mm refractor do?
The Explore Scientific 80mm Refractor’s light-weight portability gives you the freedom to observe or image the night sky from various locations! It is a true-element apochromatic telescope capable of producing research-level image quality.
