Hah... When planetary imaging is the plan, I would never expect to see good seeing, good transparancy and low jet stream all on a night that didnt involve rain!
You've done well considering the conditions... One thought... You have 12" of aperture at your disposal, I would definitely consider investing in a 5x powermate.. When you do finally get that one or twice a year night of great steady seeing, you'll want to be read with the most magnification your scope can handle..
