Notes:* Berkeley 7 is a little offset to the west (right) of center to include the Dark Nebulae complex LDN 1343 (the CDS lists 10 other named dark nebulae in this area). The * is to indicate that my cooling fan quit working again near the end of the first night, when the set point was -15c; thereafter, I set it to -10c, as the evenings have been cool enough to run at -10c at about 60-70% power. Also, the seeing has been worse than usual, due to the off-shore (Santa Ana) winds we have been experiencing this past week
