- U Her, SS Her (mira)
- BL Lac (blazer)
- HR Aur, KR Aur, AM CVn, R CrB, SZ Her, RZ LMi, DY Per, GK Per, ER UMa
- 61 Cyg
- Late Evening Session (3.2 hrs), - Operated under automated control / remote control - Ambient Temperature 5 deg C - CCD operation -25 degC (at 71% average cooling). - main objective of the session was to collect images of gallery objects (mainly Caldwell objectives) that were not easily acquired using previous 8" LX200 - secondary objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - - -
