- AM CVn attempt failed (hardware)
   
Bullet Astrometric Monitoring - Nearby Stars
 - DX Cnc, 61 Cyg, Groombridge 34, EV Lac, CN Leo, LAMOST-HVS1, Teegardens Star
    
   
- All-Night Session (7.7 hrs net)

Session operated in fully automated mode, but monitored over remote connection for 1st half of session.   An unexpected / unhandled dome closure at 01:55 and a computer crash/reboot at 03:47 caused the lost of  4.5 hours of potential observing time.

Sky quality good, good seeing.

- Main aim of the session was to acquire images of a selection of nearby stars, variable stars and deep sky objects taking advantage of moderate weather conditions. Secondary aim was to test recent  changes and additions to AstroMain program
   
- 12" LX200 + ST-10XME for imaging
- TS 80mm APO + ZWO ASI178MC for guiding & imaging
- Ambient Temperature:  -7°C (minimum) 
- CCD Temperature:  -30°C (68% av. power)

Image
CCD Image (200% size, square root scale, cropped)
Image details as above

Image above (2019-02-02.906) was taken 7.6 days after discovery of
a potential TNS AT2019agw  (Type Unknown), discovered on 2019/01/26.338
 by Catalina Real-Time Transient Survey and Nikolay Mishevskiy
 (Rochester Supernova site |  Discovery Image )
 
The discovery image on SNhunt site doesn't look convincing to me
and I don't see any sign of AT2019agw in my image.
