I had a surprise session last night. The forecast was for poor transparency and cloudiness, just as it has been for weeks, so I did not open up the observatory. But while taking out the trash at about 8:45pm I saw plenty of stars -- including some of Orion's shield stars, which is pretty good for my suburban location. Dew was fairly heavy and transparency was indeed poor -- but I thought it would be worth trying to observe. I aligned the scope on Rigel and slewed over to M42, which looked ok with full aperture, but seeing of the Trapezium stars was poor, so I masked down to 8-inches to get good Airy disks, and raised the scope to observe in Taurus. Wrapped it up at 10:45pm when seeing and transparency grew worse.
I should mention that I have been able to observe the sun in H-alpha almost daily; our weather pattern is such it clears around noon but will cloud up in the evening.
