APO Structure

Apochromatic triplet uses a series of three lenses. It provides better correction of aberration and significantly reduces dispersion. It reduces chromatic aberration, and it corrects for two wavelengths to reduce spherical aberration. The apochromatic triplet objective provides high-quality, sharp and high-contrast images.

Elimination of Stray Light

Blackened inside and knife-edge baffle are for reduction of stray light and improvement of image contrast.

Why should SV209 be used together with SV550？

SV209 1.0x Flattener Corrects the Field for Astrophotography M63x1 Connection Black.

It is a special flat field mirror developed for SV550 80F6 OTA, which can effectively improve the image quality of SV550 OTA edge field, while maintaining the focal length and focal plane position of the Objective lens. The sv209 is equipped with M63 extension cylinder and M48 adapter ring to ensure that the rear intercept of the flattener is the astronomical conventional 55mm length.
