Session Aims & Highlights (2022-06-26)

Main aims

  1. Observatory Computer. Perform nightime session test using Observatory Computer and ensure systems and devices are working correctly together. This will be the first session attempt since the computer had a complete reinstall of Window 10 and all observatory software (2022-06-21 to 2022-06-23).
  2. AstroMain. Check out new 3.52 version of AstroMain. Ensure that new version hasn't introduced any new issues and that fixes and improvements are working as per design. 
  3. PHD2 Calibration. Perform a new calibration of TS80/178MC profile . 
  4. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by time & twilight conditions.

DeviceHub 6.6.0.12

DeviceHub was updated on Development & Observatory Computers today (2022-06-26) from version 6.6.0.11 to new 6.6.0.12 version. 

This new version contains a change to returned dome slewing value after initiating a SlewToAzimuth command, following correspondance with author of DeviceHub over an issue with DH Dome returning to normal polling (every 5000ms) too quickly after a SlewToAzimuth command.  This was a problem when using Pulsar Dome where AstroMain's dome client was unable to 'see' short <= 5 deg dome slews (nor the first part of longer slews), but would instead suddently see the result of the slew some 5.1s later.

6.6.0.12 Release Notes
- Simplify DomeManager command logic.
- Ensure that short slews are handled correctly so that the client can get the downstream driver's Slewing state immediately after the command is issued.

Activity Log
After installation of the new version the Activity Log Capacity value (which was reset to its standard default value (125000) during installation ) was again increased ten-fold (1250000) by editing the DeviceHub configuration file (see notes DeviceHub 6.6.0.10, 2022-06-02 )

Results
Daytime testing showed that DeviceHub 6.6.0.12 made no practical difference to the data recieved by dome client and didn't resolve issue with 'seeing' short slew (<= 5 deg).     No issues found with new version during S1020A session attempt (2022-06-26) or during S1020 session (2022-06-27).
