3x3 Raster ScriptNotes for the script: We turn OFF guiding for all images. After two offsets (10" in one direction, back to centre then 10" in the other) we come back to the centre. We start guiding on guide bundle 1 to recentre the star then turn it off again and take a central image
50
6102:31Object18020.200Central Image- No Guiding during any images, but we guide when it comes back to the centre just to centre up the star. Had another crash so lost ~30 mins. Also Spector was in Normal mode so we paused script and changed to Fast after Exposure 61
