Session Aims & Highlights (2023-02-10)

Main aims

1. ST-10 Imaging. Demonstrate that the problems with dew/condensation inside the LX200 telescope tube have been resolved.
2. Camera Rotation.  Rotate ST-10 camera to 180.0 +/- 0.1 deg following its reattachment to telescope. Rotate ZWO 178MC camera on secondary scope to 0 deg + /- 0.2 deg, following incident that accidentally rotated camera in last session ).
3. Resync telescope.  Resync telescope pointing and carry out short mapping job to tie into TPoint Model.
4. AstroMain. Test new AstroMain version (3.61.1) following several changes since that version 3.61.
5. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions including comet C/2022 E3 (ZTF)

Highlights

• ST-10 Imaging. ST-10 Imaging through the LX200 telescope was back to normal following major problems with dew/condensation inside the telescope during the last session.
• Telescope Sync.  Telescope was successfully resynced and tied back into the TPoint Model by using a Short Mapping Job (11/12 points mapped)
• Camera Rotation. Both cameras were rotated to their required camera angles.
• AstroMain. There was a small issue with AstroMain 3.61.2 (due to accidentally leaving in development trace code that wrote of mutiple messages to the log file) and the opportunity was taken to install a fix (3.61.3) at a convenient point in the sessions which was when the Scope required parking and restarting after conducting a short mapping job.
• Dome Slews.  No hold-ups during any of the nights dome slews (Hold Up Stats: 0/25 slews affected, 0%, 0.3 minutes total hold-up time).
• Targets. Due to cloud only 8/31 targets were completed with a further 5 targets partially completed.  Out of these images from 4 target were later rejected due to cloud

Notes:

• Camera 1 Angle Adjustment:  180.84° (Start), 180.11° (End), 180.08° (repeat), 180.10° (repeat)  (vs desired angle 180.0° +/- 0.1 deg)
• Camera 2 Angle Adjustment:  356.8° (Start), 358.0°, 358.9°, 358.6°, 359.3°, 359.8° (End)  (vs desired angle 0.0° +/- 0.2 deg)
   
• Queue was stopped by user at 18:31 when it was thought that SBIG Camera assembly had slipped (as it did in the last session, S1095), due to orientation of image in TheSky6 Virtual Sky) but an observatory visit proved that this concern was invalid. Camera was at its normal angle and the perceived problem was due to cloud/  obscured view at the target location.

Minor Issues

• Unable to open "Submit ToO" form in AstroPlan. Clicking ">> ToO" button on Targets Form in AstroPlan 1.36.1 didn't open the Submit ToO form (basically nothing happened when button clicked).  This  prevented the insertion of a target into the running Job Queue. Issue investigated and the problem quickly found by running the program in debugger on development computer (exception due assignment  T.TargetID = TargetID as T is Nothing).  Problem was due to TTargetRecord having been changed from a structure to a class in AstroPlan 1.36 (2023-01-31).  Bug fixed in AstroPlan 1.36.2 by changing the declaration in SubmitToO.vb from  'Dim T as TTargetRecord' to 'Dim T as New TTargetRecord').  Issue fixed in-session by the installation of the new version (AstroPlan 1.36.2) onto the Observatory Computer.
  Fixed in session 2023-02-10 (AstroPlan 1.36.2)
   
• Foc1FieldsUpdate and TempMonitor threads frozen for 3 minutes (18:51). The ObsOverseer raised two Red Alerts at 18:53:07  "Foc1FieldsUpdater appears to be frozen (last cycle at 18:51:26)" and "TempMonitor appears to be frozen (last cycle at 18:51:35) in section 'Get CcdTemp Data', and equivalent warning messages were reported.   Foc1FieldsUpdater and TempMonitor threads were already running when the session was commenced.   A user request to connect Camera1 to CCDSoft was made at 18:50:43.78, and the SBIG Camera was reported connected at 18:51:00.95 (15s later).  ObsOverseer logged a message at 18:51:42.02  that "Foc1FieldsUpdater is Pending (15s)" (corresponding to freeze point at ~ 18:51:27 ) For some unknown reason there was a second request to connect Camera1 to CCDSoft at 18:52:57.14, but by this time Foc1FieldsUpdater was already frozen.  ObsOverseer logged "TempMonitor is Pending (132s)" at 18:53:47.19 (corresponding to freeze point at ~18:51:35). Although both freeze points are comfortably after the time that SBIG Camera was reported connected 18:51:00, a potential association is still postulated.   Issue was fixed by a user request to 'Restart CCDSoft (incl. SBIG Camera reset)', which allowed both thread to resume which were reported with message  " Foc1FieldsUpdater has resumed again (18:54) after 3.2 mins" and "TempMonitor has resumed again (18:54) after 2.9 mins".   Although issue was fixed there was an exception during ConnectCamera() at 18:54:35.17 "The remote procedure call failed. (Exception from HRESULT: 0x800706BE). The exception was logged twice.  This might relate to the earlier second User Request to Connect Camera.   which had also become frozen but then released with CCDSoft was killed. Once the Restart CCDSoft operation went onto power reset the SBIG Camera and restart CCDSoft & Reconnect to Camera, everything worked fine.   ConnectCamera() routine already sets bRunningConnectCamera to True whilst operation is in progress.  AstroMain 3.61.4 modified so that Camera1_IsAccessible() returns False if bRunningConnectCamera =True, which should block Foc1FieldsUpdater and TempMonitor from trying to access CCDSoft.Camera before it is ready. It is hoped that this fixes the issue.

• 9 minutes lost at start of autostart sequence whilst waiting for fresh shutter data to be recieved (20:00 to 20:09).  By design the AutoStart Initiation process waits until one or more of the data values coming from the Pulsar Shutter is seen to change and thereby confirming that fresh data is being received and that the data link between Dome Control Unit and Shutter Unit hasn't stalled.   But it can take some time for one of the fields (battery voltage, battery percentage level, battery amps (milliamps), temperature) to change. On this occasion the wait was 9 minutes. Whilst the check is a valid one the time taken (9 minutes in this case) is too long and represents wasted time that could instead have been used getting started with focusing the scope and start target imaging etc). The pre-start check process should be reviewed. Is they a better way to proceed ?  Allowing the process to proceed at least to the point that dome needs to be opened would be a step forward and reduce the overall wait time. A new "Skip PulsWait" check box (cboxSkipWaitOnFreshShutterData) has been added to AstroMain 3.61.6 to allow the user to skip ObsManager's 'wait for fresh shutter data'.
  Fixed 2023-02-14 (AstroMain 3.61.6)

Small Defects

• Log file containing mutiple trace messages concerning Focuser1 power. Trace messages concerning Focuser 1 power state are being written to logfile every 1-2s making it difficult to follow sequence of normal messages. This was due to development tracing code lines being accidentally left in the AstroMain 3.61.2 build.  Issue fixed in-session taking opportunity of a required operation to park & turn off the telescope to pick up and start a new program version (3.61.3). 1391 of these 'Focuser1.PowerState (trace)' message were later removed from the session's log file.
  Fixed in session 2023-02-10 (AstroMain 3.61.3)
   
• Report formatting for the 'Measure Camera Angle  (Cam2) ' needs improving (19:52).  After the operation uses a ReportTitle() to produce an underlined report section title "Measure Camera Angle (Cam2)" the call to take locate image produces another underlined section title "Take Locate Image (Camera2, PHD2)". This second title is inappropriate and break the flow of the report console messages.  The second title should be written via a ReportSubTitle instead.  Similar formating issue applies for "Measure Camera Angle (Cam1)"

• When "Observatory Door has opened" is reported a preceeding blank line isn't given. Zigbee  HandleSensorChange() routine was changed recently to put in a blank line when 'Device.Id = zbObsDoorSensorID And InStr(S, "has opened")' but this isn't working.  Fixed in AstroMain 3.61.4 (condition needed to use 'Device.Id = zbSensObsDoorSensorID ....)

• Focuser1 (TCF-S) Fields are blank are starting Focuser1 Service.  After starting Focuser1 Service the 'Position', 'Temperature' and 'Temp.Comp Position' fields are blank.  These read-only textbox fields are updated by the program by set the following virtual fields VM.Foc1Position, VM.Foc1AvTemperature & VM.Foc1TempCompPosition.  These fields are updated by the UpdateFoc1Fields() routine which is called from the Foc1FieldsUpdater Loop (RunFoc1FieldsUpdater) but only when Camera1_IsAccessible() = True.  These fields remain blank until after the connection to CCDSoft.Camera is made.
  Provided Focuser1 is connected & accessible it should be possible to show Focuser's Position and Temperature values as these don't depend on CCDSoft.Camera., but keep other fields that do depend on Camera connection blank.

• Focuser1 (TCF-S) Fields are not reset to blanks when Focuser1 and .Foc1FieldsUpdater Services are stopped.

• Red alert issued "AstroMain UI appears to have stopped responding" when Starting Observatory Services (18.54)  The ObsOverseer raises this alert if GuiChecker is finding that a simple BeginInvoke operation to post a string value to a specific TextBox in AstroMain's form is taking more than 5s to finish.  This Red Alert is commonly raised near the start of program on the Observatory Computer when Observatory Services are being started and it is hypothesized that the UI is very busy during this period with multiple routines starting up equipment and connections with changes to multiple components on the form and multiple messages being written to the program's multliline Textbox (console ).  However following an investigation (See Investigation : Cross-Thread Problem & Non Responsive UI, 2023-02-11) it is concluded that the UI thread appeared to be temporarily frozen because the operation to Start Focuser1 service is performed in the objConsole form's main thread using objConsole.Invoke(Sub() StartFocuser1() in order to prevent "Cross-thread operation not valid" exceptions when disconnecting the focuser. A solution to the issue has been found and implemented in AstroMain 3.61.4.   Future sessions to be monitored to see the problem has been resolved.

Continuous Improvement

• When 'Measure Camera Angle' is first used, or used again after other activity, a special report section should be started, with a bookmarked entry and a hyperlinked entry in the contents.htm file. ReportLineTitle() to be used to allow the section to be readily found when reviewing the report post-session.
  Done 2023-02-11 (AstroMain 3.61.4)
   
• 'Check/Reset Telescope Pointing' should be made a special report section with a bookmarked entry and a hyperlinked entry in the contents.htm file. ReportLineTitle() to be used to allow the section to be readily found when reviewing the report post-session.

• 'Start Observatory Services' should be made a special report section with a bookmarked entry and a hyperlinked entry in the contents.htm file. ReportLineTitle() to be used to allow the section to be readily found when reviewing the report post-session.
  Done 2023-02-11 (AstroMain 3.61.4)
   
• Query:  Check that certain operations 'Reset Telescope Pointing', 'Mapping' cant be started when session is in automated mode. Extra safeguards added in AstroMain 3.61.4
  Done 2023-02-12 (AstroMain 3.61.4)  
   
• Consider defining a Mapping Run as a OID group and allow JPG pictures and associated picture images (AllSky pics etc) to be accessed from the "Local Files" web page. Mapping Point images would need to be be converted to JPG pictures, at the moment they're not so this would be a new feature.  Code  'Session.ObservationUid = Session.ObservationUid + 1 added to ResetScopePosition() routine and manual RunShortMapping()  New ConvertMappingImageToJpg being developed. Included in AstroMain 3.61.6 and successfully tested at the beginning of session S1098 (2023-02-13).
  Done 2023-02-13 (AstroMain 3.61.5)
