High Quality Celestron Deluxe Tele Extender for Telescope. 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 instruments 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 telescopes eyepiece (larger eyepieces may not fit the inner diameter of the Tele-Extender), 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-Extenders 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 youll see through your cameras 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. Otherwise, it will be posted the next day. I have been trying my best to reduce my P&P c harges for all my clients.
