Color Filters for the Planets

This PDF file contains the tables and notes used the PowerPoint program that was given at the regular club meeting this year. The first section list each planet and the filters best suited to improve or enhance various visual planetary features. A narative description of the visual performance is present by Wratten filter number and color type desciption. 

A table format is next, listing each Planet, planet feature and filter most suited to enhance the visual viewing of the feature. This is good to use at the scope since it fits on on 8 x 10 sheet of paper.

The last section list the Wratten number, the planet it is to be used on and the feature on the planet the filter will enhance. This is the most common method that suppliers and dealers display their filters.
