Attaching a CCD Camera
The Orion f/3.9 Newtonian Astrographs are equipped to accept CCD cameras with a 2" nosepiece, or a 2" coma cor- rector in place of the nosepiece, which slides directly into the telescope’s focuser like an eyepiece (Figure 5). The 2" nosepiece is secured with the two thumbscrew locks. If your CCD imager does not include a compatible 2" nosepiece, or if you wish to utilize the camera’s

Removing the Piggyback Camera Adapter from the Tube Ring
If you want to install an optional mounting plate atop the tube rings for piggyback attachment of a guide scope, you’ll need to remove the piggyback camera adapter first. To do so, first remove the tube ring from the telescope. Then unthread the plastic ring from the threaded bolt. Peel back the felt lining on the inside surface of the tube ring where the bolt is located; peel it back just enough so that you can access the bolt head with a screwdriver. Using a Phillips screwdriver, remove the bolt from the ring. Now, replace the adhesive felt over the area where the bolt head was. Now the rings are ready to accom- modate a mounting plate for your piggyback guide scope assembly.
The Orion f/3.9 Newtonian Astrographs were designed with a couple of special enhancements to maximize the contrast of your astrophotographs and visual images. One is the inclusion of multiple baffle rings on the interior of the optical tube. The 8" model has 9 baffle rings and the 10" model has 13. These baffle rings block the transmission of
