SV550 APO Triplet Refractor 80 F6 OTA For Visual & Deep Sky Astrophotography

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

The High Performance

Apochromatic 3-element Objective

The triplet apochromatic optics structure (1 piece of S-FPL51 low dispersion ED glass + 2 pieces of correction glass) is adopted to significantly improve the image quality of the captured image (15.8% increase by the spectrometer calculation). Significantly reduces edge dispersion resulting in blue fringing problems.

2.5 inches 1:10 Dual-speed Focuser

The 2.5-inch focusing base can effectively reduce the vignetting problem when connecting to a full-frame camera, and the FPL51 APO can improve the quality of the captured images.

The Elimination Of Stray Light

4 extinction light bars are used inside the lens barrel, which can eliminate all stray light interference on the inner wall of the lens barrel.

Focal Lenght of 480mm
