  RX And, U And, Z And, SS Cyg, U Gem, BL Lac, SZ Lyn, CN Ori, CZ Ori, FO Ori, FU Ori, NV Ori, DY Per, GK Per, ER UMa
   
Bullet Astrometric Monitoring - Nearby Stars
  None
- Late Evening/Night session (6.2 hrs duration).
Clear skies. Wind 0-5 mph.  Moon 87% phase
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature:  -3.0degC (minimum)
- CCD operation -30 degC (at 63% average cooling). 
- Planned objectives of the session were to monitor selected variable and nearby stars. As conditions where good images were also taken of C/2013 US10 (Catalina), two other fainter comets and a number of deep sky objects in Leo, Hydra, Virgo and Coma Berenices

NGC 2835 - Spiral Galaxy

NGC 2835 (Hydra)
Image taken at altitude of only 6.5 deg, galaxy is only just visible due to
high airmass (8.2) and bright moonlight (87% phase)

Abell 33 - Planetary Nebula (PLN 238+34.1), attempted imaging

Abell 33 /  PLN 238+34.1  (Hydra)
 Planetary Nebula is unfortunately not visible in the image due to the object's very low
surface brightness and prevailing bright moonlight (87% phase). 
The catalogue position and extent of the Pl.Neb is shown by the white circle.
The bright star directly south of the nebula is the mag +7.2 star HIP 47369.
