- All night session (14.5 hrs duration).   Very good seeing, almost windless. Moonlight and high thin cloud. - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  Temperature falling progressively from +2°C at dusk to a minimum of -2.0°C by dawn - CCD operation -25°C (at 57% 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.   -   -

 Nova Delphini 2013 - Nova

Nova Delphini 2013 (Delphinus) Nova Delphini was discovered on 14th August 2013 by Japanese observer Koichi Itagaki at magnitude +6.8.  Koichi had imaged the same field the day before and nothing was visible at the same location. The progenitor star was identified from archive images as being magnitude +16.9 The image below was taken 474 days after discovery when the nova had faded to around +13.1
