在网上找到了这么一个网页，介绍了一些市面上的摄像头，主要是CCD的，并且列出了一些相关参数说明是否适用于天文摄影。现在可用的廉价CCD主要集中在840K和900NC上，希望这个网页上介绍的东西能给大家一些新的启发。

WEB CAMERASFOR ASTRONOMY IMAGING Web-cameras come in all shapes and sizes but not all are suitable for astronomy imaging purposes. The table below lists some specification details for the more common cameras which have been available recently and attempts to rate them for this work - where opinions have been expressed by QCUIAG members. Note - this is a very rough classification, based on personal opinions. Where a camera has been modified for long exposure capability to Steve Chamber's design, this is recorded in the table and is linked to the modifier's web-pages (where available). The information for the cameras has been gathered from their manufacturers' web-sites and from comments made on the QCUIAG forum, so the accuracy cannot be guaranteed by me. Unfortunately, much of the information which would be useful to us, like CCD type, light sensitivity etc. is not available for all cameras. Furthermore; specifications and models change frequently so most of these cameras are already no longer made but some can still be obtained either from retailers or 'pre-used' off the web .However, prices and availability cannot be quoted here due to the wide variations between different countries. It's generally agreed by those who have tried them, that CMOS based web cameras are not yet sensitive enough for astronomy use other than for imaging the moon and brightest planets, but, this may be changing. If you have any information to help fill in the blanks, or if your favorite web camera has been missed off, please e-mail me with the data and its source to this address or via the QCUIAG mail list at [email=qcuiag@yahoogroups.com]qcuiag@yahoogroups.com [/email]Thanks to those who have sent me details - very helpful. See this page for photos of these cameras and of the Sony ICX098 and Sharp LZ24BP CCDs. See this page for a list of miscellaneous web cameras, none of which, as far as I know, have been modified for long-exposure work - if you have modified one and have details on a web-page, let me know.
