Baader 31 mm Hyperion Eyepiece - Black

Product Description

Baader 2-inch Aspheric eyepieces Aspheric 2-inch eyepieces offer compelling features of high star brightness, unmatched colour fidelity, low weight and an attractive price.The eyepiece design includes an aspherical lens as used in many modern camera lenses, which come as a standard to offer good imaging performance over the entire image field while remaining small. The aspherical eyepiece design allows less surface area and, in conjunction with the extreme quality of the Phantom Group, a multi-coated aspherical eyepiece provides a bright, high-contrast image.The aspherical field of view is only minimally larger than that of the human eye (68) at 72. This way you don't need to be constantly checking left and right. Many wide-angle eyepieces offer a technically impressive field of view of at least 80 which cannot be checked over in one glance, and the light available is distributed over an excessively large area so image brightness and contrast are compromised. The wider the view of a wide-angle eyepiece, the harder the job of the eyepiece designer. Extreme wide angle eyepieces and wide-angle eyepieces with a simple lens design often result in the phenomena where if you move the eye very easily back and forth or sideways, the image field is immediately gone. This is frustrating.Aspheric eyepieces avoid this problem.In direct comparison, all observers note that an aspherical eyepiece shows finer stars and weaker structures in gaseous nebulae than a much more expensive 2-inch wide-angle eyepieces. The progress of technology is especially dramatic to see here.Photographic adapter thread for all types of projection photography:all popular digital single-lens reflex camera compartments with and without lenses as well as charge-coupled device cameras can be screwed directly by means of M43 on the side of the eye or the SP 54 system thread. A huge selection of adapter threads and transition rings have been chosen for this purpose. You can change your telescope focal length almost arbitrarily if small star fields or planetary objects need to be documented with higher resolution.Precise instructions are enclosed with each eyepiece.System suitability for projection photography:Each aspherical eyepiece is equipped with screw threads on both sides in order to install it as a projection system fixed on an optical beam path. On the telescope side, a 2-inch Schmidt-Cassegrain thread is located in the eyepiece.Binocular stereoscopic observation with aspherical eyepieces Aspherical eyepieces are the only 2-inch wide-angle eyepieces with long focal length that can be connected to Astro binoculars. In addition to the 2-inch receptacle, every 2-inch aspherical eyepiece is, therefore, enclosed a 1.25-inch receptacle with a 2-inch Schmidt-Cassegrain thread, which allows the use of an aspherical eyepiece on any telescopic binoculars. The minimum viewing distance should not be less than 56mm.
