    The Meade Research Grade Orthoscopic eyepieces completely changed between 1975 and 1977. Here we see the Meade Research Grade Orthos in the following focal lengths- 4mm, 7mm, 10.5mm, 16.8mm and 28mm. Substantial differences in just a short time. Also Meade apparently sold what was classified as Series 1 Orthoscopic eyepieces in barrel sizes from 0.965 which is the Japanese standard to 1.25 inch size the American standard. Hence this advertisement helps offer proof that the sought after Meade Research Grade eyepieces actuall date back into the 1970's and not 1980's as some faithful users have suggested. S & T Jan 1977.
    Between 1977 and 1979 Meade had introduced a "Series 2" Orthoscopic line of eyepieces available in both the 1.25 inch barrel size or the Japanese standard barrel 0.965 inches. The "Research Grade" line of both Erfles and Orthoscopic are of course retained and were successful for many more years before production ended. Both the Series 2 Orthoscopic eyepieces and Research Grade are all described as multi-coated and parafocalized. Note that several 2 inch eyepieces are also advertised - a 60 mm Kellner and a 32mm Erfle . (They are not described under a Research or Series 2 ocular.) This is per S & T - Sept 1979.
    Several examples of the Celestron Silver top Plossl eyepieces from the 1980's. Shown are the Japanese 22mm, 36mm and 26mm. Note the double dots above the "o" in the word PLoSSL on the above eyepieces.
