| | Astrophotography with a QuickCam |
 | | After this, I built-in the round, "naked" Connectix BandW QuickCam PCB into plastic parts, added a part from a Barlow lens, so that the CCD can now be nicely and safely attached to my telescope, in the focuser, at the place where otherwise sits the lens. |
 | | The underlying explanation for this could be that the Connectix QuickCam is not cooled, so that it is not at a constant temperature during the whole observation run. |
 | | Remember that I had not removed the IR filter from the QuickCam, and that I use a brightness setting of 254, corresponding to an exposure time of 2.62 seconds (operating in transfer mode 1, to obtain an image size of 320 by 240 pixels). |
