Huehnerhoff After checkout Russet and I investigated the odd pointing from the previous night. The secondary and tertiary where homed. The errors were large but not large enough to confirm they were the cause of the pointing errors. After getting on sky pointing for APOLLO, ECHELLE, and DIS were all very good. Made new echelle slitviewer mask. Poor seeing first have improving second half.
