School Affiliation. . . We are now asking Educators and their classmembers to furnish the name of their school affiliation on the image request form. This action is being taken to help us focus our resources towards our primary focus, getting young people in schools interested in science via real science with a neat electronic project. If you are an amateur astronomer instead, please so indicate, and we will still try to work with you. All of us here have been amateur astronomers at some time.
Numerous filters are available for astronomical use.
For a description of the filter characteristics, see filter characteristics . For help adjusting your exposures, see estimated exposure times . It may take a few days to a few weeks to process the image request. This is influenced profoundly by weather conditions, and will vary greatly. Once the image has been taken, both the original request and the image will be compressed into a file with the same filename as your request, but with a .ZIP extension.
