With an Omegon Astrograph, it's easier than with standard telescopes. Why? The answer is obvious: an f\/4 focal ratio means a lot of light with reduced exposure time. Enter the world of deep-sky photography and admire faint galaxies or details in hydrogen nebulae. The Omegon Astrograph will take your astrophotos to the next level...\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOverview of advantages:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ef\/4 Astrograph: ultra-fast aperture ratio telescope for minimal exposure times\u003c\/li\u003e\n\u003cli\u003eShort design suitable for medium mounts\u003c\/li\u003e\n\u003cli\u003eLarge field of view for extended objects: illumination of approx. 24 mm\u003c\/li\u003e\n\u003cli\u003eParabolic primary mirror with 94% reflectivity for clear images\u003c\/li\u003e\n\u003cli\u003eLarge secondary mirror: good illumination with DSLR cameras\u003c\/li\u003e\n\u003cli\u003eStable 2\" focuser with 1.25\" adapter and 1:10 reduction\u003c\/li\u003e\n\u003cli\u003eFaster cooling = faster observation: fan for the primary mirror\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003ePrimary mirror with f\/4 and 94% reflectivity\u003c\/b\u003e\u003cbr\u003eAstrographs are ideal for visual observations, but their full potential is only unleashed with astrophotography. With an f\/4 focal ratio, they are among the \"fastest\" Newtonian telescopes, allowing you to take photos with a shorter exposure time.\u003c\/p\u003e\n\u003cp\u003eThe secondary mirror and the parabolic primary mirror made of BK7 have a reflectivity of 94%, offering clearer and higher-contrast images. Compared to the \"usual\" 88% reflectivity, the difference is more than evident.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNo shadows, only light: large secondary mirror\u003c\/b\u003e\u003cbr\u003eAttach your DSLR camera or a modern CCD camera to the telescope and enjoy impressive illumination across a very wide field of view. Thanks to its large secondary mirror (read more below), you won't notice any shadows. It's even perfect for observing with 2\" wide-field eyepieces.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFewer errors, more satisfying images\u003c\/b\u003e\u003cbr\u003eThis telescope stands out for its short design and focal length. This astrograph is about 20% shorter than f\/5 optical tubes, so it can also be attached to medium mounts. This way, you'll have good equipment without the need for heavy and expensive mounts.\u003c\/p\u003e\n\u003cp\u003eAnother advantage is its short focal length, which makes this astrograph the perfect telescope for observing wide deep-sky objects. This system corrects tracking errors better than telescopes with a longer focal length. With it, you can capture stunning snapshots with little effort.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e2\" Crayford focuser with 1:10 reduction\u003c\/b\u003e\u003cbr\u003eWith Omegon's V-Power focuser, you'll achieve perfect focus for every celestial object. The 1:10 reduction ratio, robust ball bearings, and guide rails ensure the stability and ease of use of this focuser. Additionally, it features an optimized design compatible with cameras weighing up to 5 kg without the risk of unwanted slippage.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum precision: smooth and exact movements thanks to stainless steel ball bearings and guide rails\u003c\/li\u003e\n\u003cli\u003eSuitable for heavy cameras and eyepieces up to 5 kg without slipping\u003c\/li\u003e\n\u003cli\u003e1:10 reduction with scale for precise focusing\u003c\/li\u003e\n\u003cli\u003eAnti-reflective grooves for high contrast\u003c\/li\u003e\n\u003cli\u003e2 to 1.25\" adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eFaster observation agility: fan for the primary mirror\u003c\/b\u003e\u003cbr\u003eOnly a slight, imperceptible hum, but with a gigantic effect: the integrated 12 V fan cools the primary mirror up to 50% faster, allowing your telescope to achieve optimal image quality much sooner.
