My last two scope acquisitions came with a Celestron K25mm and a Celestron OR18mm, both volcano tops. I also recently acquired a Meade MA25mm. Using them I have been pleasantly surprised by the views these old EP's give in my classic refractors. So much so that I'm looking to complete either the Celestron set or the Meade but I'm leaning towards the Celestron's. Given that I have the 25 and 18, what should my next move be? I don't know much about what was available back then, but I assume there were some higher power EP's available. What were they?
