Bullet Abell 39 Attempt - Planetary Nebula (PLN 47+42.1)
Bullet M101 - spiral galaxy with supernova 2011fe
 
Bullet Variable Stars
Bullet Photometric Monitoring - Variables
- R CrB, CI Cyg, SS Cyg, AM Her, U Her
Bullet Astrometric Monitoring - Nearby Stars
- Barnard's Star
- Evening session (1.2 hrs duration). 
preceded by attempt to recharge CCD camera desicator delaying start by 1 hr 30 mins.
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature: 6.5 deg C (minimum) 
No dew.
- CCD operation -20 degC (at 83% average cooling).  
- main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to attempt to image planetary nebula in Hercules.
