Model # TS-PR-3150 Wt: 29.6 kg / 65.1 lbs Sharp & Contrasty Planetary Viewing • Fully Coated Optics • 0.89 arc-sec resolution • Less chromatic aberration than conventional achromats Design Chromatic aberration of achromatic refractors increases as their aperture increases. This becomes especially apparent for achromatic refractors with short focal lengths (less than f/8) with apertures larger than 120mm. To compensate for this, Vixen's "Neo-Achromatic" refractor has an additional two-element objective lens behind the primary objective lens, to give a bright image with excellent color correction when compared to conventional achromatic refractors with the same aperture. NA130SSWT-SXW "SPHINX" The NA130SS optical tube comes on the new "SPHINX" (SX) mount with the SX HAL110 tripod (adjustable from 70cm to 110cm). A 7x50 finder scope, 20mm & 5mm LV eyepieces, 2" eyepiece adapter, flip mirror diagonal, half pillar and extra 1.9 kg counterweight all come standard with the package.
