The SV550 APO triplet 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 APO refractor is an absolutely upgraded version of the SV550 80mm. The refractor gathers more light, and offers more clear and detailed images, suitable for deep sky photography and observation, for galaxies, nebulae, star clusters and even some fainter deep sky objects, due to the higher limiting magnitude.
SVBONY SV550 APO Refractor Telescope
The SV550 APO Triplet refractor is a compact refractor with 122mm aperture, f/7 focal ratio and 854mm focal length. It is a great travel telescope for astrophotography and observation. The OTA weighs only 6.44kg/ 14.18lb, easy to carry out when fitting into the carrying case.
Superior Performance
1. The APO triplet refractor features a 122mm aperture and 854mm focal length,which is an absolutely upgraded version of the SV550 80mm. The refractor gathers more light, and offers more clear and detailed images, suitable for deep sky photography and observation, for galaxies, nebulae, star clusters and even some fainter deep sky objects, due to the higher limiting magnitude.
2. 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.
3. The length of the dovetail is as high as 300mm, longer than the length of most dovetails. It can maintain the balance to the greatest extent, and it will be more convenient in the adjustment process.
4. 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.
FPL-51 Triplet Apochromatic Lens Structure
-
FPL51 Triplet > FPL53 Doublet -- Just For Better Clarity
The SV550 122mm adopts a FPL-51 triplet apochromatic lens structure which contains one piece of ED glass. The triplet lens provides better correction of aberration and significantly 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.
Compatible With 2-inch Interface & M63*1 Threads
The 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.
