Note: This diagonal can only be used with refractor telescopes and some catadioptric telescopes like Schmidt-Cassegrain, Maksutov-Cassegrain, etc. It not meant for use with Newtonian / DOB reflector telescopes or other variants of Newtonian telescopes.

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. It is an absolutely upgraded version of the SV550 80mm. This refractor has a higher limiting magnitude, can gather more light, and provide clearer and more detailed images. It is very suitable for deep sky photography and observation, especially for galaxies, nebulae, star clusters, and even some fainter deep sky objects.
