What does Celestron reducer corrector do?

With the Celestron Reducer/Corrector Lens, that’s precisely what you get. Explicitly designed for Celestron Schmidt-Cassegrain telescopes, this unique lens reduces your telescope’s focal length and f/ ratio by 37%, turning your long focal length telescope into a fast, short focal length instrument.

Do I need a focal reducer for astrophotography?

Telescope focal reducers provide a brighter, wider image and a reduced exposure time. Telescope focal reducers also work as field flatteners, reducing field curvature to provide the flat field necessary for astrophotography.

What does a focal extender do?

A Focal Extender does exactly what the name implies; it extends the effective focal length of the lens that it is used in conjunction with, thus producing higher magnifications for imaging and visual applications.

What is the difference between a Barlow lens and a focal extender?

They both do the same thing, but differently. The typical Barlow has 2 or 3 lens elements, and actually increases the eye relief on a given eyepiece when used with the barlow. This may or may not be desirable. The focal extenders or Powermate (Televue) have 4 elements, and will maintain any eyepieces given eye relief.

What kind of lens does a Celestron reducer use?

Reducer/Corrector f/6.3. This combination focal reducer and field corrector lens accessory works with all Celestron 5″, 6″, 8″, 9 1/4″, 11″ and 14″ Schmidt-Cassegrain telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality.

What is the focal reducer for a C5 telescope?

The Reducer/Corrector is f/6.3 for C5, C6, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope. If offers wide fields of view with any Schmidt-Cassegrain telescope.

How does the SCT corrector work on a Celestron 11 “?

The diagram above shows how the SCT Corrector improves the off-axis spot size on a Celestron 11″ SCT. Performance is similar on other size telescopes. The exact focal length of the reducer/telescope combo depends slightly on where in the optical path the SCT Corrector lens is placed.

When do I need to order a Celestron field corrector?

DUE TO EXTREMELY HIGH DEMAND, WE WILL NOT BE TAKING NEW ORDERS UNTIL MONDAY, DECEMBER 14. This combination focal reducer and field corrector lens accessory works with all Celestron 5″, 6″, 8″, 9 1/4″, 11″ and 14″ Schmidt-Cassegrain telescopes
