Bullet NGC 7673 - Spiral Galaxy
Bullet P/2014 L2 (NEOWISE) - Comet
Bullet NGC 2771 - Spiral Galaxy with Supernova ASASSN-14iu
Bullet UGC 8331 attempt - Irregular Galaxy (M51 Group)
 
 C2014 E2 (Jacques) failed due to poor seeing
 
Bullet Photometric Monitoring - Variables
 - RX And, U And, W And, Z And,  TT Ari, CI Cyg, SS Cyg, S Cyg, U Gem, AM Her, BL Lac, CN Ori, CZ Ori, FO Ori, FU Ori, NV Ori, RU Peg, DY Per, GK Per, FG Sge, U Sge, V Sge, WZ Sge

Bullet Astrometric Monitoring - Nearby Stars
 - Ross 248 (HH And), 61 Cyg, Groombridge 34, EV Lac, Teegradens Star

- Evening session (5.2 hrs duration).  
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature:  0.5 degC minimum
- CCD operation -25 degC (at 62% average cooling). 
- main objectives of the session was to monitor selected variable stars & nearby stars and to take gallery images of a range of deep sky objects.  (Poor sky conditions & moonlight hindered attempts to get any good images)
