A great many filters in common use in astronomy are used in order to improve the resulting optical quality in observations and photographs [1-4]. The majority of these filters are also capable of improving image quality in microscopy and photomicrography. Several instances of this have already been reported in this magazine [5-6]. Some new types of RGB-CCD astro filters have recently been developed for multi-shot techniques [2]. These filters can also be regarded as interesting tools for photomicrography that can maximize the quality of true color imaging based on RGB-splitting and multi-shot techniques. The respective methods and their technical benefit are presented and discussed below.

RGB-splitting and multi-shot techniques are routine tools in some fields of professional studio photography and astronomical photography. They can lead to visible improvements in sharpness, resolution and color balance. To obtain maximum image quality, special multi-shot cameras can be used. These are fitted with a multi-shot sensor that does not require any color filters. Therefore, each pixel is sensitive for all colors and pixel interpolations are not necessary.
