Celestron 93640 Overview

Ultratelephoto photography is easily achieved with your telescope by purchasing this Celestron SLR Camera Adapter with Integral 2x Barlow Lens.  You'll need to take precautions to minimize vibrations, such as locking up the mirror if possible as well as using a cable release or remote control to fire the shutter.  This SLR adapter's got a built-in 2x barlow lens to assure that any telescope can achieve proper focus, but many telescopes will be able to use it with the barlow attachment removed if you prefer.  It will depend upon how much in-travel your focuser barrel has at its disposal.  It can, of course, also be used on a catadioptric scope which has a 1.25" focuser barrel.

First, remove the eyepiece. Next, attach the SLR camera adapter where the eyepiece would normally be attached to the telescope, and screw in a T-mount adapter to the opposite end of the SLR camera adapter. Now you can attach your camera to the T-mount and you are ready to begin taking pictures!

Note:
Your camera will need to be in fully manual exposure mode, although some brands of camera may also work in aperture-priority autoexposure mode.  Additionally, if there is a switch on the camera which chooses the focus mode, that switch must indicate manual focusing.
Inserts in to 1.25" focusers
Requires T-mount SLR adapter (listed here as accessories)
Incorporates 2x magnification
Built-in barlow lens can be removed (some telescopes will not focus properly without barlow)

Odd tube construction for 1.25

Got this to attach my camera to an older telescope. The way this adapter is machined there is quite a bit of slop with the female end of the focus tube. Hard to lock in tightly.

Excellent beginner lens

I purchased this to go with a new Celestron telescope I received for Christmas and to begin playing around with astro-photograpy. I also purchased the separate Canon camera adapter and they seem to work well together in the time I've had to play around with them! My interest in astro-photograpy is very beginner level at this point, but hopefully it will help me dip my toes in the water more and begin to learn more about it as I go. It was not a very expensive piece either and I think it's a great tool to start learning on!
