| I used a Creative Webncam because one was sitting on my desk |
The first step is to open the case. |
Using a small screwdriver pry open the
case and discard the focusing ring. |
 |
 |
 |
| Unthread the eyepiece from the CCD and remove the lens. |
Drill out the lens cavity to the same
diameter as the id of the threaded section of the lens enclosure. |
Drill
a hole in the bottom of a film canister to accomodate the lens holder. Cut off the ring at the top of the canister so it will fit into your eyepiece holder. (1-1/4") |
 |
 |
 |
| Insert
the threaded eyepiece holder into the bottom of the canister |
Fit
this assebly about haflway down the cannister. |
Now screw the lens holder back onto the
CCD. |
 |
 |
 |
| Now slide the cover down the tube and snap it into place. |
Hook
your new webcam eyepiece to your favorite telescope and go have some fun. |
Hint:
Keep the film cannister cover. Use it to keep your CCD clean and free of dust! |
Below are the results of some preliminary experimentation with my webcam eyepiece.
| JUPITER |
|
 |
 |
| SATURN |

The images were very small and hard to focus at the prime focus of my Meade 8" LX6 f/6.3.
My next experiment will involve modifying the camera again and trying eyepiece projection for a larger image.
