[ Prev | Next ]

Critical Issues

• None

Major Issues

• None

Minor Issues

• Reporting of Sky Brightness (SkyAduRate) is sometimes working (giving expected values) and sometime not (giving values of 0). This can happen within the same target where for example the Conditions section and locate frames report 0, whilst Main Images later on report expected values (eg 34) , and at same time Sky Brightness can be reported as 0, but CloudAduRate is showing an expected number (e.g +14).  AstroAllSky report file shows SkyAduRate & CloudAduRate being meassured from 23:44  to  00:09.  Yet  AstroMain reports 0 at 00:01,  00:03,  00:04, but reports 25 at 00:05, 00:07, 00:09. Possibly fixed. Bug found 'SkyAduRate = TP2.NextTarget(i).SkyAduRate' was missing from GetCloudInformation() routine. Fixed attempted.
   Fixed 2021-10-03 (AstroMain 3.43.2)
   
• Reporting of Av.Sky Properties (target) is failing with message 'Average sky brightness & excess values not available' . Check Conditions section and locate frames reporting are also indicating  0 for SkyAduRate.  Bug found, .n = .n + 1 was missing from update stats section in TP2.ParseDataRecord() routine. Fixed
   Fixed 2021-10-03 (AstroMain 3.43.2)
   
• VRVR Seq Mode not being applied.  RR Lyr had 3 frame sets planned (3 x V & 3 x B using VRVR, followed by 3 x S using VVRR).  Although 2 sets were specified to use VRVR seq mode, they were taken using VVRR mode such that the images were taken in the sequence :  VVV BBB SSS, rather than expected sequence : VV VB VB SSS.   TakeMainScopeFrames() routine had been recently modified to handle 'Auto' Seqence mode.  Bug found in the logic in recent code block which was setting seq .mode to VVRR instead of retaining existing value.
   Fixed 2021-10-04 (AstroMain 3.43.3)
   
• New routine TakeCam2ReferenceImage() failed due to PHD2 failing to connect to SBIG camera (Cam1). New routine is intended to take a 10s reference frame using Cam2 (TS80+178MC) when Guiding is not used (on Vega and other short duration targets). It wasn't the intention to use Cam1 (LX200+ST10).  PHD2 is evidently being asked to connect to the wrong camera. Bug found (code was using Phd2.ConnectCam1Profile instead of Phd2.ConnectCam2Profile).  PHD2 also gave the error message "Cannot connect equipment when Connect Equipment dialog is open" which may have also contributed to the issue.
   Fixed 2021-10-04 (AstroMain 3.43.3)
   
• M31 w/AT not guiding.  PHD2 showing a modal dialog with warning about Cam Library Darks not able to use by newly selected.  Had to manually acknowledge the message and manually initiate guding for the remainder of the target. May not be able to do much.   This occured after PHD2 was accidently set to use equipment profile that uses the SBIG camera.   This was resolved in-session and shouldn't be a normal problem due to fix in TakeCam2ReferenceImage() routine, however it may be an issue further down the road when intentionally switching PHD2 between ZWO Camera profile and SBIG Camera profile. 
   Closed after review 2021-10-04 (Session, PHD2)
   
• Poor guiding for Target 1/25 (NGC 6500).  Star located in western sky. Guide star drifting north.  No Dec correction being applied as a 'North' guide mode was selected Should be Guide South. Dec guiding manually turned and then a little later set to Guide South.  PHD2 guiding then quickly brought the star back to the lock position. It's rare that Guiding Initiation fails to pick up the correct direction of star drift and sets an incorrect Dec Guide mode.  A fix has been attempted in AstroMain 3.43.4 but it requires a live test to confirm resolution of issue or requirements for further tweaking etc.
   Done 2021-10-07 (AstroMain 3.43.4)
   
• Further instance of TheSky6 / TeleAPI error 'Failed to create instance of the scope driver (POTH.Telescope)' on development computer even though TheSky6 was previously using TeleAPI / DeviceHub.Telescope'  TheSky document 'Clair_S611_NewTPointMapping3.sky' . TeleAPI is set to use ASCOM.DeviceHub.Telescope according to Registry.   Although POTH.Hub has been deleted it is still showing as a Key in ASCOM Profile.  POTH.Hub key deleted, to make it less like to be chosen.  Regedit:  shows VirtualStore/Machine/Software/WOW6432Node/SPACE.com/TheSky TeleAPI-ASCOM Plugin/  ASCOM Driver ID = ASCOM.DriverHub.Telescope.  Problem last occurred ahead of session S909 (2021-08-27).   There is suspicion (2022-05-16, See Session DH 6.6.0.8 Upgrade, S1010) that the issue occurs following each update to DeviceHub (which uninstalls old DH version / installs new version). However the issue didn't arise after upgrading DH to 6.6.0.10 on 2022-06-02.  Important to point out that the issue does not occur on the Observatory Computer (it is restricted to Development Computer).  The issue shares some similarity to a problem seen around 2022-07-14 (S1022A) when TeleApi Settings began showing blank Telescope field and not saving a fresh selection following a Windows Update which was resolved by starting TheSky6 one-time as adminstrator (see Investigation -  Can't Connect TheSky6 Scope (Blank TeleAPI, following Win Update), 2022-07-14).
   Resolved, 2022-05-16 (Development Computer, TheSky6/TeleAPI, Windows Update)

Small Defects

• TargetName logged against Start & Stop SkyStatsCollection is invalid. Log file shows 'C:\Data\CCD Imaging\Targets\' instead of target name (GCVS BL Lac). This is due to a code error which referes szTargetListFolder instead of szTargetName.  Fixed
   Fixed 2021-10-03 (AstroMain 3.43.2)

Continuous Improvement

• When Starting PHD2 and SharpCap Services the reporting messages get messed up if PHD2 and/or SharpCap are not open and are auto-opened. When PHD2 and SharpCap are auto-opened (because they are not already open) an extra ReportComment("Ok") is added upon starting each application which causes the subsequent ReportComment ("Ok" , "Started (22:39) (IP: 127.0.0.1 Port: 4400)" )  to be pushed onto the underlying row, without appropritate intent. Bug found (code not honouring the passed parameter 'bReport=False' which was designed to supress report message such as "Ok" in RunApplication2 () character.
   Fixed 2021-10-04 (AstroMain 3.43.3)
