Stars found on slew. After 2 exposures, the clouds arrive in force. We stay open for the rest of the night, but get no useful data. swing shift notes: ------------------ Afternoon checkout went without problems. spectro focus check: -------------------- Cartridge 9 Temp=11.7 C The first check had b1 & r1 far enough out that I made an adjustment.
