Objects Session Notes
Bullet M1 - Supernova Remnant ("Crab Nebula")
Bullet M110 - Elliptical Galaxy
Bullet C/2015 ER61 (PANSTARRS) - Comet
Bullet M52 - Open Cluster
Bullet M38 - Open Cluster
Bullet Hickson 46 - Galaxy Cluster
   
Bullet Photometric Monitoring - Variables
  None
   
Bullet Astrometric Monitoring - Nearby Stars
  None
- Evening session (4 hrs duration).
Generally clear skies, but cloud developing on occasions and towards end
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Main aim of the session were to test dual scope/dual camera operation with autoguiding
- 12" LX200 + ST-10XME for imaging
- TS 80mm APO + ZWO ASI178MC for guiding
- POTH Hub
- PHD2 Guiding
- Full Automated Operation  (i.e. integrated imaging &
  guiding using CCDApp2 & PHD2 automation)
- Secondary aim was to acquire some deep sky images
(including images of M1)
- Ambient Temperature:  ~ 0 degC (minimum)
