Stuart is spot on.
I remember that ? asked.
At the time i to had a 10"SCT. And at the time I found the 22 panoptic very good indeed.
I remember one observing session and I had the 22 in the scope.
Someone came along and said that's the best view of Saturn they had seen tonight. I said how so?
The person said
"that's the clearest view they had seen"
The 20 - 25 mm range will give you the best over all view with your scope.
So on a budget say a 20 or 25 mm Plossl Tele Vue.
Or more bucks 22 Panoptic. 22 Vixen LVW or 20 mm Pentax XW.
Or more bucks again 22 Nagler.
Any of the above will serve you well.
Happy eyepiece hunting.
