Founded in 2003 by Don Goldman, Astrodon was initially formed in order to distribute his innovative color-balanced RGB filters. These "Tru-Balance" filters would soon be joined by the introduction of maximum performance narrowband filters, as well as the MonsterMOAG Off-Axis Guider. Next, Astrodon acquired Schuler Astro-Imaging UVBRI photometric filters to enter the research market. Prior to being acquired by Astrodon, these filters were constructed of three different colored glasses fused together. Don improved on the design by building the UBVRI filters in the same fashion as all filters made by Astrodon, with a single high quality 3 mm thick fused silica substrate fully coated with hard oxide sputtered coatings. Finally, Astrodon added Sloan (SDSS) filters, featuring the highest throughputs and amazing durability for use during extended research projects.


Astrodon was acquired by Optical Structures (known by most amateur astronomers as FarPoint) in 2018 but all specifications on all Astrodon filters will remain at the same high standards. With Astrodon, you can count on receiving the most durable, high performance, user-friendly filters available anywhere.
