Critical Issues

Major Issues

None

Minor Issues

Images of Targets 1/16 (NGC 3656) & 2/16 (NGC 3759A) were unacceptably trailed due to failed guiding. Targets were positioned at Az 163°, Az 85.8° and Az 181°, Az 87.3° and guiding failed because the guidescope's view of the night sky was obscured by the observatory roof, even though the main scope could see the sky ok. Stars in 3x180 This is a common issue for targets which lie close to zenith for some/most of the image time.The issue was recorded with Target 2/17 during the previous S1002 session. To avoid this issue targets shouldn't be included in the observing plan at times where it's position lies close to zenith. Fixed in AstroPlan 1.29.15, Altitude checked against GuidingMaxAltCutoff (84°) in GetAltScore() routine.
Fixed 2022-04-24 (AstroPlan 1.29.15)
Target RA Slewing accuracy has decreased over recent sessions. RA pointing is typically out by 3 or 4 arc mins (W adjustment - 3.95) whilst it was spot on back in Jan/Feb. Whilst Centering operation correct this issue it is assumed that scope may need to be resynced followed by a short mapping job & restart. It was noticed today (2022-04-24) that the Observatory Computer's computer time was out by 21s. which was due to a failure to restart Dimension4 (TimeSync) program after a computer restart required for Windows Updates. Following a time sync update and continued time-syncs by Dimension 4, it is possible that slews will become more accurate again. Monitor slew accuracy during next session. Computer Time were previously encountered in 2020 after upgrading AllSky Computer to Windows 10. Computer time on Observatory and AllSky/Weather Computers drifted by 120s (as reported 2020-10-08, S817) Computer time issue believed to have been finally fixed by upgrading Dimension4 to version 5.31 (2013) on all observatory computers on 2022-04-24 and setting it up to run as a service (all using the server ntp2.uk.uu.net). Confirmed as resolved 2022-05-05 arfet reviewing good slew results from sessions S1004 - S1006.
Resolved 2022-04-24 (Observatory Computer / Dimension4)

Small Defects

AstroMove's 'List Program Versions' routine fails to report version number for TrigParallax program on local computer. Problem caused by executable being generated as 'TrigParallaxProject.exe whilst AstroMove expected the program to be named 'TrigParallax.exe'. Assembly name & Root namespace changed from 'TrigParallaxProject' to 'TrigParallax' in the TrigParallax Visual Studio 2022 project (1.2.1). CopyExe and GetProgramVersion() routines in AstroMove 1.9.1 modified to remove special handling for TrigParallax ( ie special reference to 'TrigParallax' + 'Project'.exe). Special handling for TrigParallax ( ie special reference to 'TrigParallax' + 'Project'.exe) removed from AstroLaunch 1.9.1.
Fixed 2022-05-05 (TrigParallax 1.2.1, AstroMove 1.9.1, AstroLaunch 1.9.1)

Continuous Improvement

Move Visual Studio Project backups from C drive to D drive. This will release 90 GB of space on C Drive.
Done 2022-04-24 (Development Computer)
Install Visual Studio 2022 onto Development Computer. And move projects over to using VS 2022 instead of VS 2019.
Done 2022-04-24 (Development Computer)
Modify AstroMove to use Visual Studio 2022/Projects location and use new VS Project Backups location on D drive .
Done 2022-04-24 (AstroMove 1.9)
Update Dimension 4 on all computers, installing it as a service. Dimension 4 (D4.exe) hasn't been operating efficiently on Windows 10 computers that have replaced older Windows 7 computers. It has be necessary to remember to start up D4 manually using 'Run As Administrator' after each computer restart . Dimension4 5.0 version (2004) has now been updated to 5.31 (2013) version and setup to run as a service and alway use the server ntp2.uk.uu.net. (see Upgrade to Dimension 4, Version 5.31, 2022-04-24).
Done 2022-04-24 (Dimension 4)

Upgrade to Dimension4, Version 5.31

Dimension4 (D4.exe) which is used for monitoring and updating Computer Time on the observatory computer hasn't been operating efficiently on the Windows 10 computers that have replaced older Windows 7 computers. It has been necessary to remember to start up D4 manually using 'Run As Administrator' after each computer restart (problem was probably due to D4 not being set to run as a service, resolved when installing v 5.31)

Dimension4 5.0 version (2004) has now been updated to 5.31 (2013) version and setup to run as a service and alway use the server ntp2.uk.uu.net.

This should mean that the Dimension4 will now automatically start up when computer are restarted without user intervention, ensuring that computer time in the observatory is always correct.

Migration to Visual Studio 2022

Visual Studio Community is used to create custom (AstroSuite) VB.Net programs for operating the observatory. It is thus a critical application.

Microsoft support for Visual Studio 2019 has recently ceased and consequently existing programs need to be moved over to use the latest Visual Studio version (ie VS 2022).
To support this the following tasks are required :

VS 2022. Install VS 2022 Community onto Development Computer.
VS 2022 toolbars. Setup toolbars and icons to emulate the setup used in VS 2019
Transfer Checks. Copy AstroMain project and confirm it opens, compiles and executes ok using Visual Studio 2022
Projects. Copy VS projects from Visual Studio 2019/Projects to Visual Studio 2022/Projects
Projects Backups. Move VS project backups from Visual Studio 2019/Projects to D:/VS Project Backups (~ 90 GB Total)
AstroMove. Modify AstroMove to refer to 'Visual Studio 2022/Projects' locations.
AstroSuite. Compile AstroSuite programs in VS 2022 as new versions, check for any issues and resolve.

Following the installation of VS 2022 and ASCOM 6.6 Developer Components the full set of AstroSuite programs were compiled, checked and then installed on Development and Observatory Computers (as at 2022-04-24).

AstroMain 3.51
AstroMove 1.9
AstroLaunch 1.9
AstroAllSky 3.16
AstroPlan 1.30
AstroShCap upgrade n/a (v 1.3.12 is still valid)
AstroVOE 1.10
AstroSN 1.8
AstroGuard 1.8
AstroProtect 1.7
AstroWeather 1.17
AstroObsCam 1.9
TrigParallax 1.2

Note : VS 2022 has still to be installed on Observatory Computer (as of 2022-04-25) but this isn't critical.
Note: Observatory Computer was finally taken to VS 2022 on 2022-06-22 as part of resetting up the computer following reinstallation of Windows 10.

Upgrade to ASCOM 6.6

ASCOM Platform upgraded on Development & Observatory Computers today (2022-04-24) from version 6.5 SP1 to the new 6.6 version.

The following installations were made:

- ASCOMPlatform66.exe
- ASCOMPlatform66Developer.exe
- Conform.6.6.8048.17861.setup.exe

Notes:
- DeviceHub noted to be 5.5.1.10 following installation (it was believed to have been 5.5.1.9 before installation).
- Following installation of ASCOM 6.6 the DeviceHub program was updated to 6.6.0.4

Upgrade to DeviceHub 6.6.0.4

DeviceHub upgraded on Development & Observatory Computers today (2022-04-24) from version 6.5.1.9 / 6.5.1.10 to the new 6.6.0.4 version.

The new version includes the following accumulated changes

6.5.1.10
- Fix Dome Shutter position reporting & disable Open/Close Shutter button when CanSetShutter is False.
- Report the Shutter position only when the shutter is Open.
- Changed default label for Open/Close button to Open Shutter.
- Added test case to ensure that CanToggleShutterState returns false when CanSetShutter is false.

6.6.0.1
- Added U/I support for displaying accumulated move amount for relative and absolute focusers.
- Added direct move amount for relative focusers.
- Updated user guide

6.6.0.2
- Show Wait cursor during Connect operations in case it takes a long time to complete.
- Enhanced circle buttons to change when hovered over or pressed..

6.6.0.3
- Improved error handling in user interface for all 3 devices.

6.6.0.4
- Changed drivers to prevent unconnected clients from changing device properties when the device is already connected via the U/I.
- Changed TelescopeViewModel, DomeViewModel and FocuserViewModel classes to prevent interactive disconnects when there are connected clients.

Trying out 6.6.0.4 it was found that it suffers from an issue whereby after disconnecting all telescope or all dome clients the DeviceHub interface shows that it is still connected to the respective device (telescope or dome). This would be expected where the Device was connected to from DH first, but not where the first connection was made from the client application.

Issue was reported to the DeviceHub author on 2022-04-24 (pm)

Update 2022-04-27
A new version (6.6.0.5) issued on 2022-04-27 for testing (see Upgrade to DeviceHub 6.6.0.5).
