CCD Images - Session 596 (2016-02-11)

Objects Session Notes
Bullet 81/P Wild - Comet
Bullet UGC 3738 - Spiral Galaxy (SN 2016ys attempt)
Bullet NGC 2988 / NGC 2991 - Spiral Galaxies
Bullet NGC 2943 - Spiral Galaxy

Bullet Photometric Monitoring - Variables
  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
- Evening session (3.0 hrs duration). Clear skies. Wind 3-6 mph.
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature:  -2.0degC (minimum)
- CCD operation -30 degC (at 63% average cooling). 
- Planned objectives of the session were to monitor selected variable and nearby stars. Images were also taken of some comets and galaxies in Leo.   Unfortunately the current bright comet, C/2013 US10 (Catalina), lay above hard-coded declination limit (where camera would be in danger of hitting the mount's fork base).   Images affected by wind shake.

Wind shake or periodic error make it impossible to confirm the supernova 2016ys in the
image below which was taken 14.5 days after discovery
