Session Notes

Abell 39 - Planetary Nebula (PLN 47+42.1) (attempt)     M101 - Spiral Galaxy with Supernova 2011fe     NGC 6058 - Planetary Nebula   Photometric Monitoring - Variables - R CrB, CI Cyg, SS Cyg, AM Her, U Her     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°C (minimum)  No dew. - CCD operation -20°C (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. -

Abell 39 - Planetary Nebula (PLN 47+42.1) (attempted observation)

Abell 39 / PLN 47+42.1 (Hercules) Planetary Nebula (expected extent shown by grey circle) is not visible  in this 20s image taken under poor quality skies  Central star is just visible
