Move to NGC 1647

subframe around faint star and tried focus

switched off subframe and recorded entire cluster

took images with 1*1 binning and various exposure times, focus filter

took three dark frames with 30 seconds exposure times

took a light frame

took images with green, blue, red filter, exposure time 30 sec

adjusted exposure time (ratios: blue 1, green 1.3, red 1.6) and took images (1=150sec) red and green, cloudy for green;

weather changed
