Comments: For the transit observation, moved the telescope by 20" in Dec to avoid dead pixel
on comparison star (C1). I reduced exp. time significantly (20s) to stay within count range,
then a bit more once counts started going above 350k. Initial defocus formed 2 peaks in light
profile for target and comparison stars, but peaks became less prominent as observations went
on, perhaps due to drop in temperature - I did not adjust the defocus further once observations
were on-going as per instructions.
