Remove the lens from your camera and attach the T-ring in its place. Since the T-ring is camera-brand specific, it will snap right on just like a lens. Next, remove the diagonal and visual back from the rear cell of your telescope. Screw the Celestron T-Adapter onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adapter. That’s all there is to it. The camera is now using your telescope as a giant telephoto lens. The magnification will depend on the telescope’s focal length. For instance, a 300 mm camera lens is considered to be pretty powerful, right? Well, if you are using an 8” SCT at prime focus, you’ve got yourself a 2000 mm lens with a lot of light-gathering capability!
Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. If you want to do longer exposures of deep sky objects with this method, we suggest using a separate guidescope or off-axis guider and an equatorial mount.

A T-ring for your specific camera model (sold separately) is required to couple your camera body to the universal adapter.
Celestron MAK T-Adapter NexStar 4SE
This sturdy aluminum T-Adapter is the accessory of choice if you’d like to attach an SLR or DSLR camera to the smaller rear cell threads of a Celestron NexStar 4SE telescope or C90 spotting scope for prime focus photography.

Screw the Celestron NexStar 4SE T-Adapter onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adapter. That’s all there is to it. The camera is now using your telescope as a telephoto lens.
Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

The Tele Vue EBX-2120 2" Eyepiece Barrel Extender increases backfocus distance and provides a mounting location for 2" (48mm) eyepiece filters. It can also help parfocalize eyepiece sets. Extender adds 1.2-inches to the 2" barrel.
Models with dual 2" / 1¼" barrels can use the extender.
The EBX-2120 makes the 12mm approximately parfocal with the 17mm and 22mm Nagler Type-4 eyepieces when used in a Tele Vue 2" diagonal.
Because the field stop is located near the bottom of the chrome eyepiece barrel, you will need to rack your focuser out further, relative to most other eyepieces. If you find that you cannot rack your focuser out enough to achieve focus, Tele Vue strongly recommend you purchase the EBX-2120. This will make Tele Vue's 55mm Plössl eyepiece approximately parfocal with the Tele Vue 27mm Panoptic eyepiece.
To achieve the best astroimages, it is important to attain the proper back-focus distance for your camera relative to the telescope it is being used with. If the back-focus distance your camera consumes is not exact, the performance at the corners of full frame imaging sensors will suffer—stars will appear elongated and not as pinpoints.
Example: RASA 8 with a ZWO ASI 183 MC PRO camera
- Required back-focus distance for RASA 8 with included M42 camera adapter: 25mm
- Back-focus consumed by ZWO ASI 183 MC PRO camera: 17.5mm
- To achieve equal back-focus distance, a 7.5mm M42 spacer ring is required
Celestron’s M42 Spacer Ring kit includes three different length spacer rings to achieve the proper back-focus distance with our popular Celestron optical tubes and T-thread camera adapters.
How to Use
Depending your method of astrophotography (DSLR or CCD/CMOS), there are two ways to use the M42 Spacer Ring. If you are using a DSLR, place the desired M42 Spacer Ring between your T-Ring and your T-Adapter for your optical tube. If you are using a CCD or CMOS camera, place the desired M42 Spacer Ring between the camera and the T-Adapter for your optical tube.
Below is a quick guide to help you determine which spacer ring to use for our EdgeHD, Schmidt-Cassegrain, and RASA 8 optical tubes:
| Spacer Ring Size: | Works best with: |
| 7.5mm | Provides proper spacing with RASA 8 for many ZWO cameras |
| 12mm | Provides proper spacing with RASA 8 for many Atik cameras |
| 30mm | Converts ZWO camera w/filter slider to 55mm back-focus standard for use with Schmidt-Cassegrain & EdgeHD |
Body
The M42 Spacer Rings are machined aluminum black anodized. The internal surfaces are blackened and glare-threaded to provide the highest contrast. Each spacer ring has a knurled surface, providing a great gripping surface for threading/unthreading. The M42 Spacer Rings are compatible with M42 x 0.75 (T-thread) camera adapters.

"Flat-top" model
A flat-top model allows closer placement of the eyepiece. Use with Newtonian reflectors, Tele Vue Paracorr, 2" Powermate, and 2" Big Barlow.
These adapters allows use of 1¼" eyepieces in any 2" focuser or diagonal.
All models feature brass clamp ring or nylon-tipped set screw for secure, no-mar locking and safety undercut.
Note: We purposely do not put 2" filter threads in 2" to 1¼" adapters. The reason is to avoid your getting upset when you insert a 1¼" Barlow and it crunches your expensive 2" filter. Safety first.
