Meade LX 200 16 "Optical Tube

Meade LX200 Schmidt-Cassegrain Optical Tube with 16 " (405mm) aperture, 4064mm focal length and f / 10 focal ratio.

Innovative optical treatment system that incorporates the highest quality in a Schmid-Cassegrain optical system on the market, with advanced Comma-free ACF optics on one side and ultra-high transmission coatings on the other hand . The comma-free optics allows the entire field of vision to be expanded without having aberrations and not to lose detail of any celestial body, it also reduces astigmatism and eliminates diffraction peaks. Top quality coatings allow you to get the maximum brightness and contrast from the image. The resolution power reaches up to 0.28 arcseconds.

As for the primary mirror , 416mm, it is oversized with respect to those listed as tube diameter (406mm). These additional 10mm allow to gain brightness intensity and a little more light. The function of the primary mirror lock is essential in astrophotography, since it avoids unnecessary displacement during a long exposure. The Zero-Image micro focuser also helps to get very accurate images.
