Filters for telescopes
Below you will find a complete overview of all available filters and their various functions. Filters make sure contrasts are observed with more clarity. What is more, a great number of observations can only be done in this way! When you are going to observe Mars, for example, you can use a yellow filter in order to get a good view of the clouds. For the polar caps you use a green filter, and so on.
Please find the manual below.
