- Evening session (4.3 hr). Very cold (minimum temperature -8 degC)
- Sessions operated under semi-automated control
- Ambient Temperature:  Minimum -8.0 degC rising to -7 degC by end of session
- CCD operation -30 degC (at 48% average cooling).  
- main objectives of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis, acquire set of Darks at -30deg.
- secondary objective was to acquire images of a few Local Group and other nearby Galaxies.  
- opportunity also taken to acquire images of Nova Aquilae 2009, Uranus and Abell 12

V1722 Aql - Nova Aquilae 2009

Abell 12 - Planetary Nebula

  

Abell 12 / PLN 198- 6.1 (Orion)
Adjacent bloomed bright star is 61-Mu Orionis

Due to proximity to the 4th Magnitude star Mu Ori, the planetary nebula is easily 
lost in the star's glare and could be consequently called the 'Hidden Nebula'
