Product description

Meade ACF-SC telescopes:

Almost every large telescope worldwide is a Ritchey-Chrétien, including NASA's Hubble space telescope. The technology used by the pros can now belong to you too. Meade's new Advanced Coma-Free System - powerful and high-precision - is within the reach of all ambitious amateur astronomers, astrophotographers and CCD photographers! It provides perfectly sharp star images, at the highest professional observatory level, over the entire field of view. The secret of coma-free system is - as the name says - the complete absence of coma, an optical aberration in which starlight is distorted and pulled into comet-like tails outside the central part of the image. Whether for observing or photography, the ACF Cassegrain optics from Meade is way ahead of conventional mass produced telescopes. It offers fantastic image quality, previously only available from Ritchey Chrétien telescopes and other exotic systems costing several times as much as the Meade system.

Advanced Coma-free Optics (ACF): Meade's ACF optical design eliminates the typical aberrations of all mirror optics. Thanks to ACF, the stars are also point-shaped right out to the edge of the image field, displaying no elongated comet-like distortions. The image field is flatter than that of classic Schmidt-Cassegrain telescopes. ACF optical systems show their strengths especially in astrophotographic applications.

Ultra-High Transmission Coatings (UHTC): This special multi-layer coating on the front correction plate provides up to 15% more light transmission. The result -brighter star clusters, finer details in nebulae and more surface detail on planets!

Zero Image Shift Micro-Focuser: Image focusing is achieved by focusing the primary mirror. This is designed in such a way that it cannot result in the mirror shifting. Precise focusing is carried out with a 1:7 ratio using a very handy lever. The models with 14" and 16" apertures (355mm and 406mm) are additionally equipped with a special fixing so that even with these more difficult mirrors the focus remains as it was set.

It not only matters which telescope you buy but also where you buy it. Our additional services:

  • We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
  • We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
