A Sony 640 × 480 CCD and the software is still limited to a 1/25th-second longest exposure. 1. 25-inch adapter replacing the lens. Note on the rear of the original lens is an infrared block ﬁlter. 2. 25-inch adapter. Note that the infrared block ﬁlter from the rear of the original lens has been reﬁtted into the adapter. 3. Solar closeup. Taken with a Toucam Pro II on a Celestron C8 at prime focus (2032mm focal length) and a Thousand Oaks solar ﬁlter. One of the problems with solar imaging is seeing the computer screen in broad daylight.

When a webcam is left running, it consumes electrical power and produces some heat, which, if left to build up in the camera, will raise the CCD temperature and increase the thermal noise it produces. Simply allowing air to circulate and take away this heat is surprisingly effective, especially on a cold night.
For example, if you display your image on the Web, the image needs to be smaller than about 800 × 600 pixels to be Web site–friendly. This allows the complete image to be displayed on most computer monitors without scrolling. If you want to print the image, then process the image to have a resolution of 240 to 300 dpi and adjust the image to be brighter in the dark areas than a Web image because most printers will not print details in the very dark areas. When sharpening the Moon, watch carefully for oversharpening and creating a bright edge at the limb.
