Leander McCormick Observatory Instrumentation: Filters


The Leander McCormick Observatory has a collection of 2-inch filters for educational uses. We have a set of standard UBVRI  broad band photometry filters. However, with the chromatic aberation present in the the 26-inch refractor only the B, V and R  filters find limited use. The default filter used is the V filter, primarily for single-band photometry of variables.
