Depends on your scope but of the two groups I'd go with the 17, 10 and 6mm because the 21mm weighs a ton and may cause balance issues and the 10mm tests much better optically on the bench tests than the 13mm.Originally Posted by James ErwinWhy are Tele Vue Ethos eyepieces often recommended in groups of three focal lengths:
21mm, 13mm and 8mm
17mm, 10 and 6 mm?
