Session Aims & Highlights (2019-09-20)

Main aims

  1. Centering Chart: Test out fixes to 'Centering Charts' (AstroMain 3.11.6)
  2. Mixed Target - Image a selection of targets, but mainly Open Clusters, Variable Stars and Nearby Star Targets due to bright moonlit sky conditions
  3. Software & Systems  - Check stability of software and presence of any side effects following ongoing enhancements to AstroMain and associated support programs.

Pre-Session Weather Forecast (AstroWeather 1.7.8)
Cloudy for most of night with skies potentially clearing at 03:00,  low probability of any significant rain
(As it turned out the evolving forecast through the late evening extended the cloud further and further through the night,
and indeed it was cloudy for the the whole night, only clearing at around 06:30 after the sun has risen.
A few spots of rain occurred at around 00:45 and 02:40)

Investigation - Slew Issues and Program Freeze at 04:34

 Immediate Response at 06:05 to 06:37
- Problem noticed at 06:05 with status of AdvMain at end of session - last response at ~ 04:34
- Screen Captures taken before doing anything showing the status of all the different programs 06:07 to 06:15

- Disconnected Scope & ASI ZWO from PHD2. Then closed PHD2
- Disconnected Scope and Dome from POTH. Hub at  06:19
(this produced immediate responses from TheSKy6 :  "POTH. The scope is not connected' at 06:19
and AstroGuard : "Exception in Main Loop. The dome is not connected" at 06:19 / 06:20
- Killed Stranded Process from AstroLaunch  at 06:37
- AstroMain then crashed 'The RPC server is unavailable'  but this is not likely to be related to earlier incident
