What is Edge HD optics?
EdgeHD is an aplanatic flat-field Schmidt optical system designed to produce aberration-free images with pinpoint stars all the way to the edge of the field of view of today’s largest imaging sensors and wide field eyepieces.
What is Celestron fastar?
Fastar unleashes the speed of your optical tube, making it up to 28x times faster. By removing the secondary mirror, imagers can place their DSLR or astroimaging camera on the front of the optical tube to image with a faster focal ratio and a wider field-of-view.
What is an optical tube assembly?
Optical tube assemblies (OTAs) are simply the tube of the telescope where the optics are housed. OTAs are a great option if you already own a telescope mount and want a new field of view.
What is an ACF telescope?
ACF (Advanced Coma-Free) is an altered version of the Meade’s previous schmidt-cassegrain telescopes that replaces the traditional spherical schmidt-cassegrain secondary mirror with a hyperbolic secondary mirror.
What is OTA only?
Optical tubes or optical tube assemblies (OTA) are standalone tubes that do not come with their own mounts or tripods. Optical tubes are usually bought to complement an existing system or to customise a telescope further.
What does the optical tube do?
The objective of an optic tube is a collecting system (usually consisting of two cemented lenses, less frequently a multilens or catadioptric system). It gives a real reduced and inverted image of a distant object near its own focal plane.
Is Meade Instruments still in business 2021?
Meade is still selling products on its site as usual. In posts on Facebook, Meade Instruments stated, “We will continue to support our products, our customers, and our network of dealers throughout this process. Our customers will remain our highest priority.
What is a catadioptric telescope?
Catadioptric telescopes are optical telescopes that combine specifically shaped mirrors and lenses to form an image. This is usually done so that the telescope can have an overall greater degree of error correction than their all-lens or all-mirror counterparts, with a consequently wider aberration-free field of view.
Which is better Newtonian or Cassegrain telescope?
Newtonians are better for viewing deep space objects. Maksutov-Cassegrains are better for observing planets and the Moon. Newtonians are better backyard telescopes. Maksutovs are more versatile and require less maintenance.
What’s better refractor or reflector telescopes?
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.
Is Meade going out of business?
Meade Instruments, based in Irvine, California, filed for Chapter 11 bankruptcy protection on December 4, 2019, following its loss of a multi-million dollar antitrust lawsuit brought by Orion Telescopes & Binoculars. The filing claims Meade’s debts range between $10 million to $50 million.
What is edgehd optics?
EdgeHD Optics EdgeHD is an aplanatic flat-field Schmidt optical system designed to produce aberration-free images with pinpoint stars all the way to the edge of the field of view of today’s largest imaging sensors and wide field eyepieces. EdgeHD optical tubes are sold separately or paired with our most popular telescope mounts.
What is the Celestron edge HD?
The Celestron Edge HD is a smart iteration of a normal Schmidt Cassegrain design. The main goal of Celestron was to provide consumers with an affordable mirror-based telescope that has a wide aperture and focal length at a consumer-friendly price.
What is edgehd Reducer Lens?
EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep-sky objects. To increase your field of view without sacrificing performance, add the optional EdgeHD reducer lens.
How much does an edge HD refractor cost?
As an example, in the price range of an Edge HD (about $1349 in the USA, or €1745 in Europe ), you’ll be looking at refractors that have an aperture of about 110 to 130mm, and a focal length of about 800 to 1000mm, whereas the Edge HD offers you with a whopping 200mm aperture and a 2000mm focal length.
