Filters work by blocking a specific part of the color spectrum, thus significantly enhancing the remaining wavelengths. The proper filter can greatly enhance the detection and perception of small details on solar system and deep sky objects. Judicious use of photo-visual filters can greatly enhance an observing session. Filters can be stacked on top of each other to obtain the characteristics of each at the same time. For each filter that is added to the optical path, some light loss occurs. Therefore, when stacking filters, it is best to use filters with higher transmission values to reduce the amount of light loss.
