Greg, you know me..... what's a tripod! :lol: What I did was press the camera lens against the window to keep it steady.
f/2.8
ISO 160 (lowest setting on my camera, might be 50 on an equivalent)
Shutter Priority set to 1 second duration
Exposure Compensation set to 0.
Very close to what I normally shoot anyway, just SP instead if AP mode. I took about 5 of these, but that was the best one.
