Svbony SV503 Telescope ED 70mm F6 Doublet Refractor for Astronomy (SKU: F9359A)

The SVBONY SV503 70 mm ED F/6 optical tube is a versatile and professional-grade telescope designed to meet the exacting demands of astrophotography enthusiasts. Packed with exceptional resolving power, an extensive stellar range, and a range of carefully optimized parameters, this optical instrument is your ticket to capturing stunning celestial imagery.

At its core, the SV503 is a classic refractor featuring a doublet lens system. To address the perennial challenge of chromatic aberration plaguing lens telescopes, the SVBONY team has incorporated a low dispersion glass lens of the S-FPL51 type. This lens, sourced from the esteemed Japanese company Ohara, is renowned for its optical excellence and plays a pivotal role in minimizing aberrations. Complementing this is the Ultra-wideband coating (SMC) which diligently eliminates unwanted reflections, enhancing image contrast for the crispest results.

The versatility of the SVBONY SV503 70 mm ED F/6 extends beyond astrophotography. It graciously accommodates both 1.25" and 2" eyepieces, making it equally suitable for visual observations.

Beyond its optical prowess, this telescope boasts exceptional mechanical precision and quality. Its robust extension facilitates the installation of heavy astronomical cameras and digital SLR cameras. Meanwhile, the CNC-machined mounting rings and Vixen foot ensure rock-solid stability for your imaging endeavors.
