Session Aims & Highlights (2019-10-11)

Main aims

1. Targets . Acquire images of selection of comets, nearby stars, variables and deep sky targets.
2. Focusing.   Move Primary Mirror Focus to a new position near middle of TCF-S focuser range.
3. Check Bug Fixes & New Features: Confirm that recent bug fixes and addition of new features have worked
4. Software & Systems  - Check ongoing stability of observatory software, drivers and equipment

Equipment & Software

• 12" LX200 and ST-10XME
•  80mm APO and ZWO ASI 178MC
•  CCDApp2, TheSky6, CCDSoft5, PHD2,  POTH Hub
•   Pegasus UPB & Motor Focus, TCF-S
   
• AstroMain 3.14.3  Astroguard 1.2.7,   AstroPlan 1.12.7,  AstroVOE 1.3.4, UPB 1.4.17  (AstroWeather 1.7.9, AstroAllSky 3.5)

Highlights

• FocusScopeNearZenith.  New routine 'FocusScopeNearZenith' and associated supporting routines are broadly working
  (working that is apart for one easily solved issue that requires Dome Slaving to turned on prior to slewing to the focus field). 
  This new routines allows scope to be autofocused at the beginning of the sessions in case the initial plan targets are close to horizon and don't have a suitable focus star.
  
• Shutdown Observatory.  Revised routine active by button was tested and successfully move the session from suspended to closing throught finished, including checking shutter was hut and parking the dome and the scope etc

Lowlights

• None

Pre-Session Weather Forecast (AstroWeather 1.7.8) Forecast showed patchy cloud up to 00:00 and then cloud thickeneing until total cloud cover at 04:00 In the event therre was a moderately clear interval between 23:00 and 00:45. Operations suspended at 23:42 and remained that way until the morning

Major Issues

• Issue with Focusing Offset (Foc1) starting on HH And. After behaving normally , and after taking two locate frames for HH And that well in Focus (#708199-200) that were in focus, and a seemingly successful Focus Profile (Good Profile (aluthough only 12/14 points successful), Best Focus at 5804,  (vs best focus prior to Profile of  5830) the Focuser was moved to 5804. However rather than setting an offset of 3580+/- the offset was set at anomously low figure of 1513.  When the filter was changed to R (including moving the Focuser to a position calculated using the 1513 offset)  the frames were badly out of focus. (with stars appearing like little donuts).  The next target (Z And) had problems image linking due to out of focus stars + cloud.  Although 1st and 2nd frames may not have ever matched due cloud, but teh 3rd/4th locate frames should have linked ok if stars had been better in focus betterA flat focus profile was made based on best focus at 3716.   Surprising this passed focus checks (checks are not rigorous enough) and the Focus Manager proposed a best focus at 3396., and the scope was moved to 3396 and the focus offset saved as 163.
  
  An interventation was made to manually enter the previous focus offset and apply it. Images of stars from the following TV Cas target were ok. with no sign of the Focus Problem  (Best Focus at 5661, Focus Offset set as 3462).  Examining Focus2.dat file, shows that there was a momentary glitch in OTA temperatures, with Focus Profile Chart showing -6.63degC  at 00:09 (compared to +8.39 at 23:59,  +1.29degC at 00:18 and +9.03 at 00:28) .   The Monitor File (recording at 2 min intervals) doesn't show any Foc Temperature anomaly through the period 23:50 to 00:30, nor do the OTA temperature graphs using the ObsEnv data passed to the AllSky/Weather Computer.
  
  Issue is characterised as Major, since without interventaion it could have lead to a situation where image linking could fail (e.g Z And),  refocusing could fail (as the focus was too far away from the DRO range being tested, e.g. Z And)
  
  Reviewing the focus table for Profile 23 shows that the 1st and last point didn't have produce a valid focus value (Object failed star test, even after repeat frames) and all values for the point including temperature was set as unknown value -99.   An average temperature was subsequently using the two bad points with the null value of -99 and 12 points with value around 8.8 producing the figure of -6.63deg seen. This was then used for defining an incorrect offset value.
  Fixed 2019-10-12 (AstroMain 3.14.4).

Minor Issues

• New 'FocusScopeNearZenith' feature needs to set Dome Slaving On. During live testing it was shown that after running equilibration with Dome Slaving deliberately turned off,  that Dome Slaving remains off whilist new 'FocusScopeNearZenith routine makes a telescope slew to the Focus Field.  On both attempts Dome Slaving was manually switched via the POTH hub. Without this Focus Scope would have failed as dome roof would have obsured the  sky from the telescope/camera.
  Fixed 2019-10-12 (AstroMain 3.14.4).
   
  
• AstroMain program crashed whilst attempting to 'manually' slew the scope via TheSky6 virtual view.   The crash happened with user manipulating program windows at the Observatory Computer. TheSky produced a message 'wrong tracking state', immediately before the crash.
  Closed for time being (2019-10-14),
   
• AstroMain's Report Manager is having problems writing to txtBox.  The Report messages are being written to .htm files normally,  but the lines that appear in the Main Form console are sometime missing or more often out of sequence.   The object is not behaving as first in, first out behaviour . This might be a major issue if issue repeats again in the next session.
  Closed for time being (2019-10-14), as the issue was not experienced in following session (S609), examination of code offered no clues to what had caused the issue and the writing to Report file is normal
  
  
• Focus Profile 17 (GSC 1224:29) and Profile 24 (Z And) both have flat FWHM profiles   due to measuring a hot spot rather than a true star.
  Examing the quadratic fit data shows negative a and c parameter values, which can be used to identify such profiles not use their results for autofocusing
