Group C Observation 2

PB, JB, AK

Patchy clouds, few breaks

Aligned and synced with Capella (18:35)

Sensor temp -14.8

Aligned on Atlas in Pleiades (18:52)

Moved telescope to centre of Pleione and Atlas

Increase exposure time to 1 second from 0.1, out of focus for first image

Moved primary mirror to focus

Focus won't be great - quite hazy, attempted the best we could manually

Experiment with different exposure times with image - at 4 seconds, reached saturation

Taking couples of images just under saturation (1s) with red, green, blue filters. using graph window, showed that with different filters, peak value of pixels changes
