SV550 APO Triplet Refractor with 80mm Aperture and Fast f/6 Focal Ratio Great Travel Telescope for Deep-sky Observation

Note:

Dear users: Recently, some users have reported problems with SV550 80F6 with CAA and EAF, please refer to our collocation demonstration plan (our 1x flat-field mirror consists of three parts by default: flat-field mirror body adapter ring). Through this plan, you It can solve the problem that the EAF thread is too short and cannot focus accurately (please note: our 1x flat-field lens consists of three parts: the flat-field lens body extension tube adapter ring, this solution requires you to remove the flat-field lens extension tube)

SVBONY SV550 80F6 APO Triplet Refractor OTA

The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, is a great travel telescope for deep-sky observation and astrophotography.

Apochromatic 3-element Objective

Apochromatic triplet, it 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.

Focal Length: 480mm

The focal length is 480mm, suitable for deep sky observation and photography, for galaxies, nebulae, star clusters and other deep sky objects.

2.5″ 1:10 Dual-speed Focuser

The gear ratio of the dual speed 2.5-inch toothed focuser is 1: 10, which makes it easy to achieve accurate focus. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, for fast focusing and fine focusing.

Elimination of Stray Light

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