Having cleaned the blue glass filter (thanks Ted), I took this image today. The seeing wasn't very good, but there is certainly more fine detail coming out with the rejuvenated blocking filter.

I'd say there is some un-evenness still - I may have to do some further exploratory work.

I was interested how the pressure and tilt tuning settings were very different today. I somehow thought they would be similar each time. I have a lot to learn!!!!
