First off, I didn't push hard to f/30 but rather to f/20.
It looked promising and seeing was quite nice for my local standards - 6 story roof top building, with scattered fireplace chimneys, though none was burning at the time.
I got the following picture, a stack of some 1000 frames per channel, in Registax and CS4.

Since it looked so nice, I tweaked collimation and pushed up to f/30. Boy, I could see fine detail on the R channel image on the laptop screen. I was glad that it was worth the waiting... only to become evident that seeing was only getting worse...
This is the best I was able to get, just some 50 minutes later...

Got to keep waiting for better skies...
