That is great Advise Ken, Observe & not just look !
I am flat out getting most people to spend even 30 seconds at the eyepiece
I was very impressed looking at the Grus Quartet with the 18" last night, each seemed to take on a different shade of grey !
I defineatly need a good portable observing seat so I can spend more time at the Eye Piece myself.
the "Stellar Seat" is certainly on my shopping list
