QC 3000 pro modification
What is the idea behind modifying a QC for telescpe viewing? Do you
actually turn it into a prime focus instrument by removing the lense? |

You are talking about the optical one, which allows the camera to be used at the telescope focus. There are also a variety of electronic modifications that have been developed to expose various features such as longer exposure times. Usually there is some sort of a mechanical modification as well, such as the addition of a 1.25" barrel, so the camera can be easily mated to a telescope. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

What modification do you have and how can I get instructions? |

Instructions for modding a QC4000 are he http://www.cloudbait.com/projects/qc4000.html . However, this is several years old, and I don't know how the cameras have changed. Still, it should give some idea of what's involved for almost any webcam. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

Remove the lens by unscrewing it from the plastic structure on the PC board. Click to see a larger image." _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

Pretty simple afterall....what about that glass or plastic covering over the
CCD? Should that come off somehow? |

If you are using reflective optics, you can remove it, increasing sensitivity at the expense of color accuracy. If you are using refractive optics you should definitely leave it on, as few scopes (even apos) can provide sharp focus over as wide a wavelength range as the sensor responds to. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |
