Highlights

•  Targets.  Targets succcessfully acquired but several spoilt due to low sky transparency
•  Poor sky.  Very poor sky transparency due to fog/haze, which affected all im

Small Defects

• Image Scale Bar for 32pc scaled 2x2 image looks incorrect (Post Session Analysis).  Whilst building Image pictures for NGC 3486 (2x2 binning) it was noticed that scale bar on 32pc scaled (382 px wide) pictures looks incorrect.  It was noticed that scale bar on 100pc/cropped and Full Size pictures also seemed to be incorrect. Examining code for ImageBuilder.DrawImage it is seen that PlateScale is hard-coded in as 1.405, which is ok for 3x3 binned images but not 2x2 binned images.   Strictly the plate scale should be taken from the Image Link information with a back up based on Image Size and Image Binning.
