Small Defects

• Detailed JPG Picture for GCVS U Mon shows the target incorrectly centred. Detailed realtime JPG pictures form Main Frames for Target 21/46 (GCVS U Mon) is not centered on the target even though target is correctly identified and highlighted with blue circle (see Fig 1). The same problem has occurred during previous observations of U Mon.  The frames are recorded by Full Frame 2x2 binning rather than the more usual Full Frame 3x3 binning used for most other targets. Target picture to be re-played on Development Computer whilst runnning in Visual Studio debugger to identify the bug (Target ID 143, frames starting from #1293162). Issue investigated using Trace statements that showed that CropY (and feasibly CropX) was being incorrectly modified as BinScale wasn't being applied and needs to be applied. Issue fixed in AstroMain 3.73.11.
  Fixed 2025-01-19 (AstroMain 3.73.11)
   
• Target Circle for U Mon is not precisely positioned on the Main Image JPG Pictures. Blue target circle for U Mon isn't positioned precisely on target object on JPG (main frames) pictures (see Fig 2). Target Circle is positioned ok on Locate Frame 1 and 2, but is positioned on the Focus Frame picture and subsequent Main Frame pictures. The same problem is recorded by T CrB  during the previous S1292 session.  Problem is due to a slight shift in telescope pointing since the final locate frame was taken and a failure to match stars and determine the necessary image shift for correcting the target X/Y position.   Potentiallly fixed in AstroMain 3.73.11 by ensuring the the 0th inventory star (brightest star) is included in the generated array of BrightestStars in Locate Frame.  This work for T CrB (issue in S1292).  Need to replay U Mon frames to check that fix also solves the issue seen for U Mon.
