I hope I wasn't the only one who observed this magnificent planet last night. I checked the sketching and AP forums but nothing yet. Hoping to read other reports and maybe see some sketches and pics.

I hadn't done an accurate polar alignment on my AP900 after using recently it at some rural sites for imaging. I started out with a guide camera on the TEC 140 and used Alignmaster to fine tune polar alignment. I use a refractor for Alignmaster to get drift align accuracy for imaging. I use the cross hairs in PHD and it is easy to see the reference star on the laptop screen when adjusting the AZ or ALT. My C11EdgeHD isn't as good for this purpose because of mirror flop between the pair of alignment stars.
I purchased a used TEC 140 in September but haven't had a lot of chances to use it on Jupiter. I was very glad I got out tonight before another weather system moves in mid week. I spent most of the time a 196 magnification with a Nag 5T6. The view was very steady. Several of the thiner bands towards the poles were easily observed. The air was a little cold so I was keeping alternating between a 5 and 7mm eyepieces. I would keep the other on a heating pad. Once my breath started to fog an eyepiece I would swap it out for the other.
Now that my mount is aligned again I will put my C11 EdgeHD back on the mount and give Jupiter another look with a bit more aperture. I will have to wait for another weather system to pass through before I get the change. Hopefully we get some steady clear air around Christmas and New Years extended weekends. Now I need to get motivated to get up about 4AM and spend a little quality time with Saturn.
