Appendix I Web Suppliers of Telescope Building Parts and Materials No endorsement or recommendation is provided or implied. The organizations listed are here because they were found in other such lists or advertisements or were personally known to someone. Those for whom e-mail addresses were available were notified that they would be listed. Those for whom there were no e-mail addresses or whose e-mail was not deliverable were sent regular letters with the same information. If there was no response to notification, the listing was removed. Quite a few listed organizations submitted additions or changes to their list of products. References to items specific to astrophotography and to Dobsonians were, for the most part, avoided. Likewise, references to subjects other than building telescopes, such as star charts, were avoided. If you are searching for some particular item or for something that will serve for a particular item you are advised to look under a variety of related categories. There is very little standardization of nomenclature in telescope design. For exam- ple, “used” usually means “buys and sells used parts and complete scopes.” Rings and mounting rings probably are overlapping categories. Diagonals, mirrors, and secondary mirrors probably all mean the same thing. Some of the listed organizations produce or distribute items useful to us telescope makers but with a much wider/different selection of clients. In dealing with them it would be useful if you are particularly clear as to the intended use. Some produce items for other industries and are set up to supply materials in large quantities. Be very courteous to them if you expect them to accommodate tiny orders.
