You can modify the XML file that stores all the instruments (camera & telescopes) and it will show up. The file is instruments.xml
On XP it is located at C:\Documents and Settings\<username>\Local Settings\Application Data\Microsoft\WorldWideTelescope\data
On Vista it is located at C:\Users\<username>\AppData\Local\Microsoft\WorldWideTelescope\data
The format of the XML is somewhat self explanatory (if you are familiar with XML files). You will need to put the technical info in yourself though too.
If for some reason you mess things up, you can delete the file and WWT will update it with the most current one that is available. One important note though, if you modify it and we update that list, we will overwrite your file so you should keep a back up.
Good luck
