Stars, moon and planets can be easily seen in the sky even with an unarmed eye and radiate their own fascination. However, objects that are very far away and thus appear particularly faint, or objects that radiate in wavelengths that are only very faintly perceptible to the human eye, can only be observed if a correspondingly large aperture is used so that as many of the emitted photons as possible can be collected. Since more and more interfering photons (light pollution) are captured with a large aperture, filters must therefore be used that allow the desired wavelengths to pass through and attenuate the interfering ones. In addition, cameras are used which, unlike the human eye, also detect wavelengths that make the recognition of corresponding structures possible in the first place (e.g. H-alpha light at approx. 656.3nm). Thanks to these technical aids, very distant or very faint structures such as other galaxies, Quasars <\/a>or clouds of matter and the exploration of the \"cosmic depths\" becomes possible \u2013 that\u2019s what we call deep sky ...<\/p>\n\n\n\n

Reports on such deep sky objects are presented here.<\/p>\n\n\n\n
