Designed and Manufactured in North America.

The patented Meade Advanced Coma-Free (ACF) optical design offers coma-free pinpoint star images and flatter image fields greatly desired by discerning amateur astronomers, astrophotographers and professional observatories alike. This ACF system also reduces astigmatism and eliminates diffraction spikes.

The ACF primary, secondary and corrector plate glass blanks are manufactured in the USA exclusively for Meade.

This telescope also features Ultra-High Transmission Coatings (UHTC). UHTC are specialized multi-layered coatings that are precisely designed to improve the performance of your telescope’s optics. You’ll see brighter star clusters, more fine detail in nebulae, and additional surface features on planets. Averaged over the entire visible spectrum, total light transmission to the focus increases by 15%.
