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.

 



SVBONY SV550 122mm Triplet Review

The author : Astro Soundscape

SV550 122mm f/7 APO OTA Refractor 854mm Focal Length

The SV550 APO refractor is a compact refractor with 122mm aperture, f/7 focal ratio and 854mm focal length, a great travel telescope for astrophotography and observation. The OTA weighs 6.44kg/ 14.18lb, easy to carry out when fitting into the carrying case.

The APO refractor features a 122mm aperture which gathers more light, and offers more clear and detailed images, suitable for deep sky photography and observation,and even some fainter deep sky objects, due to the higher limiting magnitude.

FPL-51 Triplet Apochromatic Lens Structure

The SV550 122mm adopts triplet apochromatic lens structure which contains one piece of FPL51 ED glass. The triplet lens provides better correction of aberration and greatly reduces chromatic aberration and enhance the clarity and sharpness.

R&P 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.

Aluminium Alloy & CNC Machined

Made from high-quality optical materials, ensuring clear, realistic observations.

Unique material processing techniques make this product outstanding in quality and durability.

Compatible With 2-inch Interface & M63*1 Threads

SV550 refractor is compatible with 2-inch and M63*1 accessories. The front is a 2-inch adapter for connecting a camera or 2-inch accessories; Rotating off the adapter, here threaded the M63*1 threads, for connecting the SV209 field flattener or other M63*1 accessories.

Lock Screw--Tighten The Lock To Prevent Focus Issue

Lock the focus, observe without distortion. The focusing thread locking device improves accuracy and longevity.

300mm V-Style dovetail

The length of the dovetail is as high as 300mm, which is longer than the length of most dovetails on the market. It can maintain the balance to the greatest extent, and it will be more convenient in the adjustment process.

 

For Visual Observation & Astrophotography

The entire tube rings have 26 screw holes + a mounting screw handle. Such tube rings with so many screw holes can be compatible with more equipment installations, like Smart WIFI device, guide scope, astronomy camera etc., meeting various needs of installations.
