In this wavelength range the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows much sharper images than are usually obtained from your device and location. Another advantage is that the sky background of advanced dawn is dark and so the filter even allows photography of the planets and the moon at daylight.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eMain use\u003c\/h4\u003e\n\u003cp\u003eThe Astronomik ProPlanet IR 742 cuts off the visible part of the spectrum and allows the light of wavelengths longer then 742nm to pass. Due to this behavior the part of the spectrum that is most sensitive to bad seeing is rejected. This approach does a big improvement to the imaging of planets and the moon. The image is more steady than the image in the visible light with nearly identical exposure times.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Jupiter, aufgenommen mit L-RGB Filtern und Astrnomik ProPlanet 742\" height=\"263\" src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/Astronomik_ProPlanet742_vs_LRGB_Jupiter.png\" title=\"Jupiter, aufgenommen mit L-RGB Filtern und Astrnomik ProPlanet 742 (Alexei Pace, Malta)\" width=\"500\" data-mce-src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/Astronomik_ProPlanet742_vs_LRGB_Jupiter.png?width=700\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJupiter, imaged with L-RGB Filtern (left) and Astronomik ProPlanet 742 (right)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cimg alt=\"Comparing sharpness in IR-R-G-B at Saturn\" src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/Vergleich_RGB-vs-IR-Pass_filter.png\" title=\"Comparing sharpness in IR-R-G-B at Saturn\" data-mce-src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/Vergleich_RGB-vs-IR-Pass_filter.png?width=700\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComparing sharpness in IR-R-G-B at Saturn\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cimg alt=\"Comparing L-RGB versus IR-RGB at Saturn\" src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/Vergleich_L-RGB-vs-IR-RGB.png\" title=\"Comparing L-RGB versus IR-RGB at Saturn\" data-mce-src=\"https:\/\/www.astronomik.com\/media\/wysiwyg\/Vergleich_L-RGB-vs-IR-RGB.png?width=700\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComparing L-RGB versus IR-RGB at Saturn\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch4\u003eOther uses\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBesides astrophotography the filter allows you to get stunning results in nature photography.

If trees are photographed in spring and summer under blue skies you get stunning images with white trees and clouds in front of a near black background.\u003c\/li\u003e\n\u003cli\u003eDarkens the background during twilight.\u003c\/li\u003e\n\u003cli\u003eImaging of bright planets, stars and comets by day.\u003c\/li\u003e\n\u003cli\u003eImaging of young stars in dust clouds and stellar nurseries.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003c\/h4\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eAlternatives\u003c\/h4\u003e\n\u003cp\u003eWhen the seeing is very bad and the instrument is 10\" (250 mm) or larger, the Astronomik ProPlanet IR 807 may be the better choice.\u003c\/p\u003e\n\u003cp\u003emore information about the photographic Astronomik filters\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.astronomik.com\/media\/produktabbildungen\/astronomik\/transmission\/full\/astronomik-proplanet-742_trans.png\" alt=\"Transmissionsgraphik\" data-mce-src=\"https:\/\/www.astronomik.com\/media\/produktabbildungen\/astronomik\/transmission\/full\/astronomik-proplanet-742_trans.png?width=700\"\u003e\u003c\/p\u003e\n\u003ch4\u003eSuitability\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eVisual observation (dark skies): Unsuitable, the eye is insensitive at this spectrum\u003c\/li\u003e\n\u003cli\u003eVisual observation (urban skies): Unsuitable, the eye is insensitive at this spectrum\u003c\/li\u003e\n\u003cli\u003eFilm photography: It depends,\u003c\/li\u003e\n\u003cli\u003eCCD photography: Reasonable, for special IR photography (as chlorophyll)\u003c\/li\u003e\n\u003cli\u003eDSLR photography (original): Unsuitable\u003c\/li\u003e\n\u003cli\u003eDSLR photography (astro modified): Unsuitable\u003c\/li\u003e\n\u003cli\u003eDSLR photography (MC modified): Very good, for IR daylight photography\u003c\/li\u003e\n\u003cli\u003eWebcam \/ Video (Planets): Very good, rejects problems with seeing\u003c\/li\u003e\n\u003cli\u003eWebcam \/ Video (Deep Sky): Very good, rejects problems with seeing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003emore then 96% transmission for wavelengths of 742nm to 1100nm\u003c\/li\u003e\n\u003cli\u003eblocking of wavelengths between 350nm and 730nm\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.
