Interesting update, Lou. I imagined the Delos line could be an excellent upgrade to orthoscopics the way you used them. (I remember how you and I observed from Cherry Springs in July 2010... time flies. Say hi to "Doc" from me... We observed from Spruce Knob in September 2008, I believe. Wow, time really flies. Coincidentally, he gave me my first look through an Ethos, at that time only the 13 had come out.)
