It seems most every scope I've owned has in someway given me a wow moment or two, or more!
Not all of them but I'd say most.
When they leave wowness doesn't seem to make a difference.
Probably the biggest WOW's came from Bluey, a Coulter 17.5", Woody, a 14.5" Starsplitter and
Mr. C14, orange vintage. All gone now.
Life here is a merry-go-round when it comes to telescopes.
I seem to have enough of them to keep me rotating over and over again, and it's like seeing a old friend.
When one leaves there is no rhyme or reason, I just flat out have like a unconscious mini stroke or
something, kisses then good bye.
