Burgess Optical Colour Filter SetBurgess Optical Colour Filters

Ten Colour Filters From Burgess Optical.

Burgess Optical is now offering color filters. These filters are Hoya filters and are available in 10 different colors.

The Hoya filters are glass and mono-coated (single anti-reflective coating).


The filters fit standard 1-1/4" threads. Each filter is threaded to accept another filter or other
threaded 1-1/4" accessory. Fully screwed into an eyepiece or diagonal, each filter protrudes an additional 5/16" (7.2mm) beyond the end of the barrel. Each filter comes in a plastic case. Each case is 1-7/8" x 2-3/4" x 3/4" (48mm x 68mm x 19mm) and comes with a friction fit cover having a clear window. Each filter has our name opposite the number of the filter.

The common color name of the filter is printed on the back of each plastic box. To easily determine the color of a filter when observing after dark (tip not needed for solar observing!), hold the filter up to your eye while looking at a bright white star. The star will be the color of the filter. If you are not observing at a dark site, just put the filter between your eye and one of your neighbor's lights. Each color is useful for bringing out planetary detail.
 

See http://sciastro.net/portia/advice/filters.htm for a good description of filters and what each color is best suited for.
