  • Converts f/10 optical system to "faster" f/6.3 for a wider field of view
  • Works with any brand and size of Schmidt-Cassegrain. Threads into rear cell.
  • Shortens exposure times for astrophotography by 2.5 times
  • Four-element, fully multi-coated optical design with 41mm clear aperture
  • Shortens effective focal length of Schmidt-Cassegrain optical system by 37%
  • Model: Celestron f/6.3 Reducer Corrector for C Series Telescopes

Review Celestron f/6.3 Reducer Corrector for C Series Telescopes / Celestron 94175:

This combination focal reducer and field corrector lens accessory works with all Celestron C5, C8, C9¼, C11 and C14 telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6. 3 for C5, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope. If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3. Celestron doesn't offer a f/6. 3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6. 3 Reducer/Corrector. [+]
Results are amazing both visually and photographically.

Review Celestron Solar Filter for Nexstar 4 Telescope / Celestron 94129:

Celestron Solar Filters are made with Baader Astro Solar Safety Film. Far superior than any existing glass, Mylar or polymer filters, they lead to brighter, sharper, and higher contrast images. Enter the millennium with the finest solar filters available. Astro Solar Safety Film is clear and homogenous and attains the optical performance of high quality plane-parallel glass filters-it is diffraction limited! Double-sided metal coatings have uniform density and good color balance across the entire field ensuring razor sharp images from edge to edge. The Sun appears in its "real "color -neutral white, not blue or orange ,and the sky adjacent to the solar limb is jet black. You can see detail in sunspots, bright faculae near the limb and the mottled areas known as granules with these filters. The Sun offers constant changes and will keep your observing interesting and fun. Even small aperture telescopes can enjoy features of the Sun. The Astro Solar film is completely safe and durable (won't break like glass if dropped). Its rating is ND-5 which means that the film transmits 1/100,000 of visible light (. [+]
001%) while reflecting (blocking) 99. 999%of unwanted light. The film absorbs all ultraviolet rays while coating reflects infrared light rendering both absolutely harmless. For added assurance, Baader Astro Solar film has been declared safe for direct solar viewing by the German National Bureau of Standards for eye safety. Celestron has previousl.

  • Model: Celestron 90° Angle Star Diagonal, 1.25".

Review Celestron 90° Angle Star Diagonal, 1.25". / Celestron:

A Star Diagonal lets you view objects that are at a 90° angle from the direction the telescope is pointing, thereby allowing comfortable viewing when the telescope is pointed at, or near, the zenith (i. e. directly overhead). The resulting image is right side up, but will be reversed from left to right.

  • Increases Schmidt-Cassegrain telescope effective focal length more than 10,000mm
  • T-ring not included
  • For use with 35mm SLR cameras
  • Attachment that allows a camera to be attached to Celestron Nexstar telescopes
  • Fits over telescope eyepiece
  • Model: Celestron Deluxe Tele-extender for Nexstar Telescopes

Review Celestron Deluxe Tele-extender for Nexstar Telescopes / Celestron 93643:

The Deluxe Tele-Extender for Schmidt-Cassegrain telescopes is a hollow tube that allows you to attach a camera to your telescope, with an eyepiece installed. By using the Deluxe Tele-Extender in combination with an eyepiece, you can increase your instrument's effective focal length to well over 10,000mm! And this corresponds with a matching increase in image size. This technique is known as eyepiece projection photography. The following formula can be used to determine approximate effective focal length:EFL = Telescope focal length/Eyepiece focal length x DF (the distance from the center of the eyepiece to the film). The Deluxe Tele-Extender is used for high-power lunar, solar and planetary photography as well as for extreme terrestrial photography. It fits over the telescope's eyepiece (even large eyepieces such as those in Celestron's Ultima line), and connects to the visual back of the telescope. Optional counterweights will be necessary to properly balance the telescope when using the Tele-Extender. To use the Deluxe Tele-Extender, remove the diagonal from your telescope and insert an eyepiece directly into the visual back. Place the Tele-Extender over both the eyepiece and the visual back, then attach your 35mm SLR camera to the back of the Tele-Extender, using a T-Ring. The Tele-Extender's built-in safety device will help prevent your eyepiece from becoming accidentally dislodged. [+]
There are a few things to keep in mind when using this access.

  • 50 degree apparent field of view
  • High power, ideal for guiding
  • Multi-coated optics for increased contrast and have long eye relief
  • Model: Celestron 94169 10mm Plossl Reticle Eyepiece (1.25 ")

Review Celestron 94169 10mm Plossl Reticle Eyepiece (1.25 ") / Celestron 94169:

Guiding (or reticle) eyepieces are mandatory for guided astrophotography. They keep a guide star stationary during long exposures to avoid star trailing. This 5-element guiding eyepiece has a reticle pattern that is a. 0075" double spaced line system. The optics are multicoated for increased contrast and have long eyerelief. The high power is ideal for guiding and it has a 50° apparent field of view. This type of reticle pattern allows you to position the guide star in the middle square or at the intersection of two lines, whichever is easier for you. An optional illuminator is required.

  • Celestron Radial Guider - 94176
  • Model: Celestron Radial Guider Schmidt-Cassegrains

Review Celestron Radial Guider Schmidt-Cassegrains / Celestron 94176:

Specifically for use in prime focus, deep-sky imaging or astrophotography with Schmidt-Cassegrain telescopes, the Radial Guider is compact and sleek in design. This accessory makes it possible to simultaneously photograph and guide through the optical tube assembly of your telescope. The Radial Guider also eliminates the problem of differential flexure, because you're both guiding and photographing through the telescope. The Radial Guider is compatible with Celestron's C5, C8, C9¼, C11 and C14 telescopes and comes with a unique prism angle adjustment screw. It must be used with a guiding eyepiece, camera T-Ring and drive corrector (dual axis preferred). Primarily for use with catadioptric telescopes, but also works on refractor telescopes having adequate back focus. This guider is a tremendous improvement over conventional off-axis guilders. Not only is the angle of the prism tunable, but it also maintains a fixed rigid camera orientation while still offering users the freedom to move the guiding eyepiece radially about 135°.

Review Celestron Microguide (12.5mm) Eyepiece 1.25" / Celestron 94171:

This multi-function guiding eyepiece features a laser-etched reticle with a built-in, battery illuminator. The eyepiece is a multi-coated 12. 5mm Abbe (four element) Orthoscopic.

The Micro Guide Eyepiece is totally free of internal reflections and offers sufficient eye relief for the reticle to be viewed easily, even with eyeglasses. Its finely etched micrometer scale has gradations 50 microns apart and 15 microns wide. Included are: the eyepiece, built-in cordless illuminator with adjustable brightness control, batteries and instructions. The apparent field of view is 42°.
