Both visual astronomers and astrophotographers alike will appreciate the quality and capability of this powerful telescope. Features a 12" aperture, 3048mm focal length, and f/10 focal ratio with Dual-Fork Mounting. Equipped with Ultra High Transmission Coatings (UHTC) and a resolving power of 0.456 arc-seconds for the improvement of brighter star clusters, more fine detail in nebulae, and greater surface features on planets. Includes a Series 4000 26mm Super Plössl eyepiece (96x), viewfinder (8x50 optical with crosshair), 1.25" Diagonal Mirror, and Standard Field Tripod. OTA and Mount Weight: 57 lbs. OTA Dimensions/Mount Dimensions: 29" x 18" x 27". Tripod Weight: 19 lbs. Tripod Dimension: 30" to 44" Variable. 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 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%.
