I'm always curious, has anyone put their premium Televue eyepieces into a f/15 Mak and compared it to their f/4 fast Refractor, and see if there that much whoa factor with a f/15 Mak?
I always one the Delite 7mm just so I can see if it will be better. I guess I never have a chance to know now.
No, but I've done the converse (inexpensive eyepieces in a fast Dob) and the results weren't pretty.
Those same inexpensive eyepieces (Meade Plossls) gave nice views in my old SCT's.
