Amateurs from all over the world can take images which were far beyond reach even for the very best equiped professional observatories 20 years ago.\u003cbr data-mce-fragment=\"1\"\u003eYou will need a low noise video-camera and dedicated image-processing like AstroStakkert, Registax or AviStack plus a infrared-pass filter to enter this field of astrophotography!\u003cbr data-mce-fragment=\"1\"\u003eWhy Infrared? Every observer knows the flickering stars and planetary disks when looking through an eyepiece or at your monitor Slight differences in temperature and preasure result in a different index of refraction for \"bubbles\" of air. As these bubbles move, the image moves too! This effect is called \"Seeing\".\u003cbr data-mce-fragment=\"1\"\u003eThis change in the index of refraction becomes smaller the further you go to the infrared (longer wavlengths), and due to that, the Seeing becomes better too!\u003cbr data-mce-fragment=\"1\"\u003eWhen observing with the human eye we have no options: The human eye is not sensitive to infrared light. But with the CCD or CMOS sensors from our camera we can go to the infrared part of the spectrum and enjoy the steady air.\u003cbr data-mce-fragment=\"1\"\u003eAn Infrared-Pass filter like the Astronomik ProPlanet 642 BP blocks all unwanted visual light and gives you infrared light only!\u003cbr data-mce-fragment=\"1\"\u003eThe amount of seeing is changeing very fast, so there is no universal filter that will do it every time. So the Astronomik ProPlanet 642 BP is the third filter in this line of Products in addition to the Astronomik ProPlanet 742 and ProPlanet 807! When seeing is no really bad, the ProPlanet 642 BP will be usually the first choice and will give you best results as it blocks the longer IR too!\u003cbr data-mce-fragment=\"1\"\u003eWhile we were developing this new filter, several observers had our prototype filters for testing.
