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 focuer 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.

Comments about Celestron SLR Camera Adapter with Integral 2x Barlow Lens:
Used with 6" Newtonian. Had tried a non-magnifying T-adapter but couldn't get the camera close enough to focus. This did the job. Moon fills up entire frame. Remote release is a must (I used a corded one).

Comments about Celestron SLR Camera Adapter with Integral 2x Barlow Lens:
So far used for digital photography with microscope. Plan Telescope use. Parts and threads fit fairly well. The barlow lens is so so. Mixed metal and good hard plastic product. Fits T adapter well.
Pleased with product relative to its pricing.

Comments about Celestron SLR Camera Adapter with Integral 2x Barlow Lens:
Once I received this lens, I attached it to my Canon Digital Rebel XT using a T-Adapter and was able to finally take a picture of the moon through my Celestron 130 SLT telescope. Previously I had used another lens, but could not get anything in focus as the lens was basically just a metal tube. Without this device, I would not have been able to accomplish this.

Comments about Celestron SLR Camera Adapter with Integral 2x Barlow Lens:
i am sure the functionality of this product varies according to ones telescope and area of viewing. unfortunately both of those are not too superb where i primarily view and photograph. this is in no way the fault of the adapter, as it works just as advertised. if i decide to upgrade my equipment or location i still have all i need to attempt good astrophotography.
