ABSTRACT:
This invention is a new innovative approach to filtered astronomical observation. The card consists of a pocket sized durable card containing the 8 most popular colored acetate filters used by amateur astronomers for planetary and celestial observations. Unlike conventional glass eyepiece filters, which requires that you remove the telescopes eyepiece to screw on a new filter for each color change, the pocket filter card has all 8 popular colors on one card, for immediate easy access without having to manipulate the telescopes eyepiece. There are many advantages to this over the eyepiece system in that it can be used on any size telescope and because the observer can so easily and quickly scan one colored filter to another, the observer can take advantage of enhanced imagery of all the colors observed due to his persistance of image imprinted in his mind. The card can be taken to any astronomical gathering and used over the eyepiece on any telescope on display without imposing on that telescope because manipulating the eyepiece to change colored filters is not necessary with the pocket filter card. The pocket filter card requires no expensive carrying case for storage, it is easily stored in a protective paper envelope which can be carried around in your pocket.
