Session Aims & Highlights (2024-10-19)

Main aims

1. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions.
2. AstroMain.  Continue to check new 3.71.8 version of AstroMain following introduction of ResolveScopePortIssue handling which includes noteworthy changes to ObsManager MainLoop code for progressing Auostart, Starting, Suspended and Closing States
3. CCDCamera.  Monitor operation of CCDSoft / SBIG Camera, & CCD Camera following issues in two recent sessions (S1254-55) but not in last session (S1256)
4. C/2023 A3 (Tsuchinshan-ATLAS). Acquire images of comet C/2023 A3 (Tsuchinshan-ATLAS)

 Equipment & Software

Highlights-

• Targets. Initial part of session under manual control and acquired images of T CrB, & C/2023 A3 (Tsuchinshan-ATLAS).  During the main automated session 23/35 planned targets observations were completed with 1 target partially completed. Other target failed due to cloud, altitude/airmass threshold or missed start due to replacement by two ToO targets (C/2021 S3 (PANSTARRS) & C/2022 E2 (ATLAS)).
•  C/2023 A3 (Tsuchinshan-ATLAS). Images of comet C/2023 A3 (Tsuchinshan-ATLAS) were successfully acquired
• AstroMain.  The new AstroMain version 3.71.8 continued to work as per design with no problems
• UPB / Telescope.  No issues with UPB Power Box Switches or Telescope COM Port.
• CCD Camera.  No issues with CCDCamera/CCDSoft freezing (apart from one case related to user error)
• LAN Connection.  Observatory's new wired Ethernet cable connection operated perfectly throughout its first live session.
• Dome. No issues opening/closing shutter during session, however dome wasn't parked correctly due to issue with Park Sensor following earlier deConz / Network problem,  and shutter battery to not charge following the session.

Minor Issues

• A SBIG Camera alert "Take Image failed (Command timed-out)"  (18:25). A SBIG Camera red alert raised at 18:25:49 with the message "Take Image failed (Command timed-out)". This was during the taking of Locate Frames, for manually initiated acquistion for Target C/2023 A3 (Tsuchinshan-ATLAS) .  Issue was due to the CCD Camera not being connected.  This was user error who had forgotten to manually initiate Connect Camera operation which is necessary when working the Observatory in Manual Mode. Connect Camera was clicked just in time for the second image, unfortunately the sky was still too bright for taking images showing stars. A separate Continuous Improvement ticket is raised for the system to check the Camera status before beginning an Ad-Hoc Imaging.

• Telescope focusing was significantly off at start of session. The focusing of the LX200 had gradually slipped over the course of the last few sessions from around 2200 step position on 2024-09-30 (S1248, see Fig 1a) to the 750 position at end of the last session on 2024-10-17 (S1256, see Fig 1b) . Initial images of C/2023 A3 (Tsuchinshan-ATLAS) suggested that it was significantly out of focus, and it was expected that focus might have slipped out the 0-7000 range offered by the TCF-S Focusers and would require the LX200's Primary Mirror Position to be readjusted to bring it back to the centre of the TCF-S focuser range.  Near Zenith focusing showed however that whilst the focusing of the system had indeed slipped, tt had in fact slipped back to the centre part of the TCF-Range and to a best focus position at 3699 steps (see Fig 1c). Fortuitously this is very close to ideal position at 3500 steps.  Whilst the telescope operated within normal focusing bounds for the rest of the session, requiring just minor tweak to focus related to airmass & temperature differences,  the underlying issue whereby the LX200 primary mirror can't be locked in position still remains unresolved (see LX200 - 'Broken' Mirror Lock & Unsuccessful Fix (2023-11-11) )

• Observatory Dome wasn't parked correctly at end of session and didn't start recharging (06:35). After parking Dome at end of session with Dome.Park() command, AstroMain conducted its 'Search of Dome Park (Narrow)' routine.  This searches the Az range 88.0 to 82.0° at 0.2° steps and identifies the narrow 1° or 1.2° range where the Zigbee Park Sensor has a Closed State, signifying 'At Park' and then takes the middle of that parked range as the Best Park Azimuth, then slews to it and syncs dome at Az 90°.  On this occasion the routine was conducted as usual at the end of which a successful Session Event was recorded with the message "Find Park found (Best Park Az 89.9°)".  A few minutes later AstroMain reported a warning "Dome hasn't started re-charging after 3.1 minutes. Dome may not have parked at correct physical Az" and 12 hours later the Shutter Battery Charts were noted to show battery level had dropped away to a value of 91%.  The 'Search for Dome Park' routine was rerun with both narrow search (+/- 2) and wide search ( +/- 10), but neither attempts could locate the Park Position and recorded red Session Events with the message "Find Park failed (Unable to detect Park Sensor in the range searched)".  So why did the Live Session detect the Park Sensor yet no park the dome with induction charger in correct alignment ? .  Investigating showed that during the whole 4° narrow search range was seen as 'At Park' and determined that Best Park Az was at 89.9° (90.0°), and explains why the successful Session Events was raised with the message "Find Park found (Best Park Az 89.9°)", and indicates that the Park Sensor was seemingly 'stuck' in the 'Closed' State (see Fig 2).   During the later post-session search attempt , the Park Sensor was seemingly 'stuck' in the 'Open' state'.  ObsPics from the session show that the Park Sensor was displayed a "P" (ie 'At Park'  /  Closed)  state for the entire session even during period when dome was actively slewing between each target during the session and very clearly wasn't Parked.  When AstroMain changed back to general session at 06:40 the ObsPics immediately begin showing Park Sensor without any "P" indicator  (ie showing it Not Parked / ie Open).   The issue was fixed by restarting all Observatory Services (including the Zigbee Service), and re-running 'Search of Dome Park (Narrow)'. This time the routine found an At-Park region extending over a 1.2° interval between Az 90.2 to 91.4° and establishing Best Park at Az 90.8° which was then synced to 90°. The problem is put down to earlier outage of the Zigbee Network (due to deCONZ not finding the Combee II device) after Windows OS restarted the computer to install networks and the delay in sensors such at the Park Sensor becoming reachable again (see Zigbee Network not available, deConz not connecting to Combee II, 2024-10-18)

Small Defects

• ScopeMonitor & TheSky6 froze for 5 minutes whilst Linking of a Locate frame (20:30).  This is a known occasional image. During Image Linking of Locate 1 frame for Target 4/35 (AT2024xig) the ObsOverseer reported that ScopeMonitor appeared to have frozen, with the interpretation that TheSky6 was temporarily unresponsive.  After 5.1 minutes (close to the typical duration) ScopeMonitor & TheSky6 resumed and the results of ImageLinking reported.  This is the second time that TheSky6 has frozen in this manner since new code was added in AstroMain that adds some delays between GetRaDec calls to TheSky.  Delays were increased after the last case but has prevented this latest case.  Log files show that the TheSKy6/Scope Monitor froze upon the call 'TheSky.GetObjectRaDec("Image Link Information")' as per case in session S1255.

• AstroMain didn't record a red alert for 5s power outage  (01:25).  A green UPS System alert was raised with the message "UPS running on Mains Power at 01:21:44 (outage time Unknown) ". However there is no corresponding red or yellow alert.  This is the same problem that was seen prior to the last session (see S1256 notes).  It is suspected that a momentary outage was spotted by UPS System (running on a 5s reporting cycle) but wasn't long enough to be registered by AstroMain Laptop Battery Monitor, or cause any other problem to the Observatory. The raising of red alert is likely tied to the computer going to battery power, and this didn't occur there was no alert. UPS Monitor doesn't post its recognition of a power outage, as this would normally result in duplicated alerts.  Perhaps the UPS Monitor should retrospectively post a red alert if the Laptop hasn't recognised the outage.  Fix attempted in AstroMain 3.71.9, with addition of flag bLaptopBatteryOutageReported which is either set True in RunPowerMonitor() (when Laptop goes to Battery power, or it remains False in which case RunUpsMonitor() will record retrospective Event/Alert records when Mains Power is restored.

Continuous Improvement

• Modify submission routine for AstroMain's Ad-Hoc Imaging to check that CCD Camera is connected or not. When performing a Manual Operated tasks at beginning of a session it is easy to forget to connect the CCD Camera, particularly after a spell of sessions which have purely involved using AutoStart at the beginning of the session. During S1257 user forgot to Connect Camera before starting Target C/2023 A3 (Tsuchinshan-ATLAS) with the result that first Locate Frame failed with the message "Image failed      (Timed-out)" and "Unable to Link Image.  Will try a longer exposure".  The button routine should check the Camera status before beginning an Ad-Hoc Imaging operation, and optionally proceed to Connect Camera first or abort.

• Create a facility in AstroMain / ImageSets Tab to retrospectively added Target Name, Target ID to an ImageSet. The image set "C2023_A3_Tsuchinshan-ATLAS 3x3 5s C Set3" in session S1257 was acquired directly from CCDSoft, and when it came to Analysis,  ObjectName, Store folder where empty (or contained 'Cursor Position') and it wasn't possible to derive Title (Distance from Sun, Distance from Earth) information or rate. of motion in Ra/Dec.  Whilst it was possible on this occasion to get the information from '.. Set2' which was acquired via AstroMain, this may not always be the case, and having a means to retrospectively add Target Name (OBJECT), Target ID (TARGETID), Tag Coordinates (TAG-RA, TAG-DEC), Offset Details (OFFSETN, OFFSETW)  details to FITS Headers would be a handy facility.   Part implemented in AstroMain 3.71.9  Object Name and Target ID implemented via Fields and Add Keywords Button on More" Tab
