Most large telescopes are Ritchey-Chrétien, including NASA's Hubble Telescope. Now you can get the equipment from the professionals. Meade's new coma-free system - precise and powerful - is now within the reach of the most ambitious astronomers, astrophotographers and CCD photographers. You will get sharp images of the stars throughout the field of view, worthy of professional observatories. The secret of the "Coma Free" system is - as its name suggests - the absence of a coma, a color aberration that makes some stars look like an orthographic comma if the light source does not come from the center of the field. So much to doobservations as photographs : Meade's ACF-Cassegrain optical systemis far aheadof conventional series telescopes. Offers afantastic image qualitywhich until now could only be obtained with Ritchey-Chrétien telescopes and other exotic systems with exorbitant prices compared to the Meade model.
ACF ( Advanced Coma-free ) coma-free optical tubes:Meade's ACF optical design reduces the image errors typical of all mirror tubes, so stars look sharp right down to their outline, without trail-like distortions more reminiscent of a comet. The image looks flatter than with classic Schmidt-Cassegrain telescopes. ACF optics are spatially useful for astrophotography.
Ultra high transmission coating( Ultra-High Transmission Coatings ):This special multi-layer treatment of the front corrective plate guarantees up to 15% more light transmittance. The result is clearer star clusters, finer details on nebulous objects, and better-defined surfaces on planets.
