I headed out last night for some visual observing from my dark(ish) site, and almost as an afterthought threw the DSLR and polarie into the car.
Here's a stack of 15x2 minute subs of the LMC with the D800 and a 180mm prime at f3.2. The 180mm does a great job framing it.
It was very windy - so much so that I felt a bit vulnerable up the ladder of the big dob. I suspect this is the main cause of the elongated stars and not the limitations of the polarie or the alignment.
Astrobin is down for upgrades - so here's a link to flickr.
