Thanks for the comments Les.
I was very surprised myself at finding NGC 3195 when later I read it was a Mag.11 Thats the highest mag Ive seen so far, and as a beginner Im quite proud of my 8" dob and my own efforts. Was a great test for my new OIII filter.
Ill try the Mr sheen trick, I find that at a particular turn point of the dob base there seems to be a little friction. I'll have to check this further.
I'll take you advise and work my way backwards in viewing clusters, leave the brightest till last. At the moment that feels a little awkward in thought as I feel inclined to start with the easier ones first then work my way to harder ones. It will be more rewarding though to view the easier ones last.
Cheers
