Which is better Schmidt Cassegrain or Maksutov Cassegrain?
The main difference between Schmidt-Cassegrains and Maksutov-Cassegrains is the corrector lens at the front of the telescope. Both scopes use spherical mirrors which induce spherical aberration. Also, Maksutov-Cassegrains usually have longer focal ratios than SCTs, making them less well-suited for deep-sky photography.
What is Celestron Edge HD?
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 are Schmidt Cassegrain telescopes good for?
They are also well-suited to a number of applications including photography and terrestrial observing as well as stargazing. Most new SCTs are computerized, adding to their ease of use and portability. Schmidt-Cassegrain telescopes are a catadioptric design, meaning they use both lenses and mirrors.
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.
What can I see with a 14 inch telescope?
14 Inch Telescopes offer exceptional resolution for their size. They can resolve double stars at . 33 arcseconds and can be magnified up to 712 times the human eye. 14″ Optical tubes also make exceptional light gatherers by allowing an observer to see 16.5 magnitude stars!
How good are Celestron optics?
At the mid-level price range, these Celestron TrailSeeker ED binoculars are just about as good as it gets and in my opinion one of the Best Value For Money Binoculars in their class….BBR Ratings:

What makes the Celestron edgehd 11 an astrograph?
The optical system on the Celestron EdgeHD 11 was designed to give an astrograph quality flat focal plane all the way to the edge of the field of view as well as reducing the off-axis star coma.
What is the difference between a Schmidt-Cassegrain and edgehd telescope?
The difference in EdgeHD optics is that they produce a focal plane more than three times flatter than that from a standard Schmidt-Cassegrain telescope and dramatically flatter than other competitive coma-free designs.
What makes edgehd the best imaging telescope?
Each vent has an integrated 50-mesh filter guaranteed to let warm air out without letting dust in. Fastar versatility – 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.
What are the best 11” telescopes?
The Advanced VX 11” Schmidt Cassegrain telescope is one of the most affordable and portable 11” telescopes; perfect for imagers and visual observers alike. The 11” optical tube offers 41\% more light gathering than a 9.25” telescope.
