How to Install Astromania Deluxe Tele Extender？
To use the Deluxe Tele-Extender, remove the diagonal or any other accessories attached to the visual back of your telescope. Insert the 1.25” eyepiece you want to use into the visual back and lock it firmly into place with one of the setscrews. The eyepiece must have a diameter smaller than 45mm, which is the inside diameter of the Tele-Extender. Many eyepieces are too large, so double-check the fit before you begin your astrophotography session. For the most secure connection, remove the second thumbscrew from the visual back body and then slide the Tele-Extender over the inserted eyepiece as well as the visual back. When engaged, the two thumbscrews on the Tele-Extender clamp onto the visual back to hold everything firmly in place, assisted by a safety shield that keeps the thumbscrews from loosening during use.

The advantages in a nutshell:
• Attachment that allows a camera to be attached to your telescope.
• The camera side of the deluxe tele-extender accepts a standard T-ring (sold separately).
• Allows you to take pictures through an eyepiece, for high magnification shots of the moon, the planets, and the sun(with the proper filtration).
• Increases schmidt-cassegrain telescope effective focal length more than 10,000mm.
• Accepts a wide range of 1.25" eyepieces, including the Omni Series.

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).
