• With a brass pressure ring; the diagonal mirror has a brass pressure ring; which can prevent surface damage and scratch marks when the eyepiece is used with the diagonal;
• Supports 1.25-inch filters features internal extinction treatment and supports the connection of 1.25-inch filters; Offering versatility for various observations;
• With filter thread; the diagonal mirror has M28.5x0.6mm filter thread; which supports the connection of 1.25 inches filter;
• 90 degrees design; the diagonal mirror 90 degrees deflection angle design; you don't have to bend over when performing visual observation; and the observation experience is more comfortable;
• Internal extinction design; the SV221 has internal extinction treatment; and the acquired image is clearer and brighter.

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.
