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\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\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\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\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\u003eAn Infrared-Pass filter like the Astronomik ProPlanet 642 BP blocks all unwanted visual light and gives you infrared light only!\u003cbr\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\u003eWhile we were developing this new filter, several observers had our prototype filters for testing. Most of them reported that the Astronomik ProPlanet 642 BP gave them the very best images compared with filters from other manufacturers. The sharpness and high contrast resulted in the best final images in nearly all situations!\u003cbr\u003e\u003cbr\u003e\u003cimg width=\"400px\" src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/gallery\/Jupiter_Michael_Karrer.JPG\" alt=\"\"\u003e\u003cbr\u003e\u003cstrong\u003eJupiter with Ganymed\u003c\/strong\u003e\u003cbr\u003e(c) Karl Thurner\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg width=\"400px\" src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/gallery\/Luethen_Jupiter_IRRGB.jpg\" alt=\"\"\u003e\u003cbr\u003e\u003cstrong\u003eJupiter With Ganymed\u003c\/strong\u003e\u003cbr\u003e(c) Hartwig Luethen\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDo you use the AstronomikProPlanet 642 BP for lunar and planetary imaging?

With the Astronomik ProPlanet 642 BP installed in your camera, it´s possible to do nice shoots of H-alpha regions even when the moon is up: Lunar stray light is filtered out very effective!\u003cbr\u003e\u003cbr\u003e\"How long do I have to expose longer?\" -That´s a very common question from custmers from all over the world.\u003cbr\u003eThe answer is quite easy: You don´t have to expose longer, you MAY expose longer!\u003cbr\u003e\u003cbr\u003eDue to the high transmission of nearly 100% you will have the same amound of photons with a wavelength of 656nm on your sensor, wether you have the filter installed or not. But, with the Astronomik ProPlanet 642 BP installed, the background sky will be very dark, while it would be very bright -or even saturated- when imaging without the filter! The filter blocks photons with other energies and give you a higher contrast. With the filter installed you MAY expose longer to collect more photons from your object of desire till the background is getting brighter again!\u003cbr\u003e\u003cbr\u003eA narrow band emission-line filter like the Astronomik H-alpha filter with 12nm or 6nm FWHM will do the job much better (it blocks more of the unwanted light), but the lower price of the Astronomik ProPlanet 642 BP is very attractive for beginners in this field of astrophotography! Additional to that the real emission line filters are quite difficult to use for beginners as focusing can be quite difficult with them. With the Astronomik ProPlanet 642 BP you will usually have enough light to use the LiveView monitor on the back of your camera!\u003cbr\u003eTaken all this together the new Astronomik ProPlanet 642 BP is the ideal filter for getting started in H-alpha imaging with your modified DSLR!\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/California_400px.jpg\" alt=\"California Nebula with Astronomik ProPlanet 642BP\"\u003e\u003cbr\u003e\u003cstrong\u003eCalifornia Nebula imaged with a Canon 80D(mod) and Astronomik ProPlanet 642BP Clip-Filter\u003c\/strong\u003e\u003cbr\u003e(c) Thomas Tomz Henriksen, Dänemark\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003emore then 96% transmission for wavelengths of 642nm to 840nm\u003c\/li\u003e\n\u003cli\u003eblocking of wavelengths between 350nm and 630nm\u003c\/li\u003e\n\u003cli\u003eParfocal with other Astronomik filters\u003c\/li\u003e\n\u003cli\u003eGlass thickness: 1mm\u003c\/li\u003e\n\u003cli\u003eCompletely resistant against high humidity, scratches and aging effects\u003c\/li\u003e\n\u003cli\u003eDiffraction limited, the filter will not reduce the optical performance of your telescope!\u003c\/li\u003e\n\u003cli\u003eAstronomik filters are delivered in a high-quality, long lasting, filter box\u003c\/li\u003e\n\u003cli\u003eSince 2008 we do ship filters with a completely new design.
