This review, "Meade's LX90-ACF eliminates coma," appeared in the December 2008 issue of Astronomy magazine The tried-and-true 8-inch telescope from Meade … Meade Instruments: A world leader in the manufacturing of Telescopes, Solar Telescopes, Microscopes, Optics, Binoculars, for amateur astronomers and hobbyists Search results for: 'Télescope Meade AC 102 mm f 800 mm f/7.8 instructions' Telescopes, Solar Telescopes, Binoculars, Spotting Scopes As is, short exposures under three minutes is allowable. This Meade 8" LX90-ACF has Advanced Coma-Free catadioptric optics that provide sharp coma-free images. The Meade Instruments LX90-ACF 10-Inch (f/10) Telescope also possesses an oversized primary mirror. I currently own a 80mm apochromatic refractor and a recently-acquired a Meade 12” LX90 LNT SCT with UHTC, the object of this review. 0000030299 00000 n The primary mirror is also oversized, so it helps to bring more off-axis light to the eye. For example, the primary mirror of 8-inch LX90’s is 8.25-inch in actual. Even though the primary mirror is a spherical one, it’s a non-issue due to its focal specs and its spherical and coma-free benefits thanks to its optical design. 0000075233 00000 n 0000007416 00000 n 0000078269 00000 n B&H Photo and Video carries telescopes and accessories such as cases, lens filters, and stands, to give you the best viewing experience.
