SVBONY SV503 102 mm ED F/7 is a professional optical tube with excellent resolving power, long stellar range and other parameters optimized for use in astrophotography.

SVBONY SV503 102 mm ED F/7 is a classic refractor with a doublet lens system. In order to correct the main optical defect of lens telescopes, i.e. chromatic aberration, the optics of this instrument are equipped with a lens made of low dispersion glass (ED) type S-FPL51, which is one of the flagship products of the Japanese company Ohara, known from the production of the best types of optical glasses. The Ultra-wideband coating (SMC) is responsible for eliminating reflections and improving image contrast.

However, the possibilities of this telescope are not limited to astrophotography only. This instrument allows you to conduct visual observations with both 1.25" and 2" eyepieces.

In addition to impeccable optical parameters, the optical tube SVBONY SV503 102 mm ED F/7 is characterized by high quality and precision of mechanical elements. A solid extension allows the installation of heavy astronomical cameras or digital SLR cameras, and the mounting rings and the Vixen foot made in CNC technology guarantee full stability of the tube.
