Transcribed Image Text:The telescope and CCD detector
described in question 2 are used to
observe a distant star cluster. The
detector has 2000 x 2000 pixels. What is

between two stars in the cluster that can
just be resolved with this observing
system if we ignore the effects of
diffraction and the Earth's atmosphere?
Assume the two stars are resolved if they
are able to fall on the centres of two
neighbouring pixels. Choose the answer
below that best matches your answer.
