Howdy Pilgrims,
I've no affiliation with this company at all, but I thought their table of TeleVue EPs to use with a Meade Lightbridge 12" Dobsonian was interesting.
It is also interesting to note that they ONLY list out their store-brand and TeleVue EPs, and don't mention the other obvious ones like Pentax XW's etc.
