Peg,
I haven't used the 8mm Orion Stratus but I have used the 17mm in both F5 and F10 scopes. I was very impressed with it as a great value for money eyepiece. The only reason I didn't mention the 8mm Stratus, was the fact it was coming back a bit in power from Shane's stated 6mm focal length and to be honest I didn't even think about it as it was not close to 6mm. Reconsidering things, if he is prepared to reduce power to an 8mm eyepiece this is a great option for him at about $AUS 180. In fact, its what I would be doing if it was my money and I was budget constrained in any way. A 7mm pentax XW its not, but its a great eyepiece for $A180, or at least the 17mm that I have tried was.
