Shot on tripod without pano head. Used a bubble level, but it was quite frustrating. The house was much too close, with too many visible angles, to be doing a proper pano... Used Hoya r72 IR and ND4 filters in nightshot mode, -2EV. Light conditions changed frequently and drastically. A total of 5 photos were used in the pano. Used PSP7 to refine, crop, and tint. Stitched with Canon Stitch that came free with my printer. :-)
