Description


Celestron's deluxe tele-extender is a high-power photographic accessory for Schmidt-Cassegrain telescopes. It's 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 telescope's effective focal length to well over 10,000mm! And with this comes a corresponding increase in image size.


It's a technique known as eyepiece projection photography, and it multiplies magnification by the distance from eyepiece center to the film plane, according to the following formula:
Effective Focal Length = Telescope focal length ? Eyepiece focal length X DF (distance to film).


The deluxe tele-extender is used for high-power lunar, solar and planetary photography as well as for extreme terrestrial photography. To employ the 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 and attach your 35mm SLR camera to the back of the tele-extender, using a T-ring. That puts you in business for fine, highly magnified astrophotography!


Note: The image you'll see through your camera's viewfinder will be upside-down. And, because of the extremely high magnifying effect afforded by the deluxe tele-extended, you'll want to take extra care to prevent camera and telescope vibration. Accurate polar alignment and using only under good seeing conditions will also help you capture high-quality images.


The deluxe tele-extender is only for Schmidt-Cassegrain telescopes!

      Comments about Celestron Deluxe Photographic Tele-Extender:

      Works as advertised. Most 2" eyepieces will not fit, most 1.25" are no problem. The 40mm Plossl that comes standard with the many celestron scopes fits no problem.

        Comments about Celestron Deluxe Photographic Tele-Extender:

        Gaining a little more magnification is useful for imaging the solar system. High powered eyepieces tend to really deteriorate the image, so I stick with the lower powered ones just to get a slightly larger image and keep good focus. It works as I expected it too. Not an essential addition, but convenient/useful at times.

          great fit. but the only thing that you have to do is take out one of the set screws on the visual back.no big deal,other wise it works great.just make sure your type of 1.25 inch eyepieces will fit.

            It fits ok, perhaps the attachment could be made better using a compression ring instead of a thumb screw.
