Session Aims & Highlights (2021-01-17)

Main aims

1. Targets. Acquire images of a selection of variable stars, nearby stars, comets and deep sky targets as allowed by conditions.
2. Software. Test features recently added to AstroMain 3.34.2

Equipment & Software

• 12" LX200 and ST-10XME
• 80mm APO and ZWO ASI 178MC
• CCDApp2, TheSky6, CCDSoft5, PHD2,  DeviceHub 6.5.1.0,  UPB 1.5, ASCOM 6.5 SP1
• Pegasus UPB & Motor Focus, TCF-S

  (AstroWeather 1.10.14, AstroAllSky 3.6.2)

Highlights

• Autostart.  Autostart worked perfectly , automated opening of the observatory and start of session at 01:06 when skies were detected to have cleared.  Apart from initiating AutoStart at 23:56 the whole session ran in an entirely automated mode.
• Targets.  x Targets successfully acquired
• Centering.  Targets centering was very good
• Autoguiding.  Autoguiding performance was good

Lowlights

•   None.

Night Sky Summary Plot Top axis: Sky Brightness at Zenith (in ADU/s) Lefthand axis: Local Time (hh LT). Righthand axis: Sun Altitude (degs)

Pre-Session Weather Forecast (API data from darksky.net) Pre-Session Weather forecast showed overcast conditions (cloud cover 100%) with possibility of light rain showers in first part of night, giving way to clear stars from 02:00 onwards (cloud cover 25-39%) with very low probability of light showers. Temperatures 5°C falling to 3°C by dawn.. Moderate Wind (13-16 mph) Observatory was set in AutoStart mode, so that session would begin would automatically commence when sky conditions became suitable for observing.   In the event skies were overcast until 01:00 (with rain at 00:45) and then remained clear until dawn except for a passing cloud with spots of rain at 02:55 Temperature of 4°C at 01:00 fell to 1°C by dawn. Winds light to moderate.

Critical Issues

• None

Major Issues

• None

Minor Issues

• The newly added 'guide star' labels are plotting at incorrect X position and are too bold. Guide Star lables where added to realtime Guide Reference and Guide Frame jpg pictures in recent AstroMain version 3.34.3.  Code was new/untested and needs to be tweaked.
  Part Fixed 2021-01-18 (AstroMain 3.34.4) 
   
• JPG Pictures numbers are jumping by 2 image frames at a time (2021-01-18 Test).  Main Images (Single Object) are jumping from Final Locate Frame 851003, to 851005 to 851007.   In test mode the Code 2 images substituted for first frame (851004 & 851005) because Trial Linking of first frame is being used,   second frame substituted 851006, third frame substituted 851007.    Question is why was 851006 picture not created.  Problem seems to be caused by FITs image file still being open in CCDSoft when ImageMagicK runs. Code added that closes image file (Image.Close() ) if UseTestMode=True.
  Fixed 2021-01-18 (AstroMain 3.34.4) 
   
• AstroPlan's Programs To Use form isn't listing M31 Transients or M33 Transients (Prog ID 45  & 46).  CV Transients (Prog ID 47) and Novae (Prog ID 48) are shown ok. Code reveals that Only Programs with Active (non-completed) targets are listed.  Neither M31 Transients or M33 Transients had active targets at the moments (they each have 1 completed target). Fixed by modifying read/count database code in ProgramsUse.DisplayPrograms() routine.
  Fixed 2021-01-18 (AstroPlan 1.19.3) 
   
• Legend on CCD Temperature Chart is collapsed, legend lines and labels are overposted. This is a bug that follows from code changes in AstroMain 3.34.4.
  Fixed 2021-01-19 (AstroMain 3.34.5) 

Continuous Improvement

• Circle GCVS stars on realtime JPG pictures, adding cross when offset is used.   Requires adding and using need LocateInfo fields (ObjectX, ObjectY, bOffsetObject and changes in ConvertsFitsToJpg () routine). RetrieveTarget code modified so that Circle  (0.5 arc min radius) is set ErrorPositionRadius isn't already set and if Target Name contains GCVS or Target belongs to a project which normally has stellar or other small target. (eg Nearby Stars, Main Variables, HyperVelocity Stars, Novae, M31 Transients or Distant Galaxies). MIght have a problem with stars having large proper motion (need to monitor)
  Done 2021-01-18 (AstroMain 3.34.4)
   
• Create replacement Rain Forecast/Weather Forecast routines using alternate API.  For the last 2 years DarkSky.net has been used to get rain radar forecast (minutely data for 60 mins) and weather forecast information (hourly data for 48 hours) in support of observatory operations and protection. DarkSky.net mas been taking over by Apple and the API resource will at some point be no longer available. There are other API sources online. A replacement needs to be found and routines for importing and processing API responses need to be built.  Work on this item finally began on 2021-10-24 (see details). Replacement open using OpenWeatherMap implemented in AstroWeather 1.14 (2021-10-28).
  Done 2021-10-28 (AstroWeather 1.14)
