IMAGING ACCESSORIES

PIGGYBACK CAMERA MOUNT

The Celestron Piggyback Mount is a great accessory for all observers

interested in deep-sky astrophotography. This mount allows you to attach

your camera, with its lens, to the top of the telescope, making it possible to

shoot with a normal or wide angle lens while guiding through the telescope.

The Piggyback adapter mounts to the rear cell of the C8, C9.25, C11 and C14

telescopes.

REDUCER/CORRECTOR F/6.3

This combination focal reducer and field corrector lens accessory works

with all Celestron 5", 6”, 8", 9.25", 11" and 14" Schmidt-Cassegrain tele-

scopes. This four-element, fully multi-coated f/6.3 Reducer/Corrector makes

it possible to have a dual focal ratio instrument, without sacrificing image

quality. The Reducer/Corrector is f/6.3 for C5, C6, C8, C9.25 and C11

telescopes and f/7 for the C14 telescope.

It offers wide fields of view with any Schmidt-Cassegrain telescope. Reduces astrophotogra-

phy exposure time by a factor of 3. Results are amazing, both visually and photographically.

DELUXE TELE-EXTENDER

The Deluxe Tele-Extender allows you to attach a camera to

your Schmidt-Cassegrain telescope, with an eyepiece

installed. By using the Deluxe Tele-Extender in combination

with an eyepiece, you can increase your instrument’s effec-

tive focal length to well over 10,000mm! 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 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 accessory. First, the image you’ll see

through your camera’s viewfinder will be upside-down. Secondly, due to the extremely high

magnifying effect afforded by this accessory, extra care to prevent camera and telescope

vibration, accurate polar alignment and use under good seeing conditions will all assist you

in capturing high quality images.
