Optical Instruments

It maybe useful to add that Ross also made fine microscopes and telescopes. Many of their telescopes were designed for terrestrial or marine usage, most having military markings. However many of their telescopes were for the civilian market, for example their fine deer stalking scopes. Although I've not seen a Ross astronomical telescope. — Preceding unsigned comment added by 78.148.36.31 (talkcontribs) 13 November 2014 (UTC)
