Connector seems properly mated however. We'll hope for the best... 22 Seeing=1.7", clear. Something is wrong with this exposure, low S/N = 11. The telescope was still focusing when the exposure started, and did not stabilize for 5-6 reads, but this could hardly be the reason for the signal here. The sky was perfectly clear where we were pointed. Mystery. 23 Seeing = 1.6", clear. 26 Seeing = 1.5", clear. 28 Skyflat, operator moved stars only moved 3.6" instead of 36!!
