PUPIL ACTIVITY - TELESCOPE IMAGE REQUEST

Avoid SINGLE stars (the interest in single stars is to monitor their changes or produce catalogues) but GALAXIES, NEBULAE and CLUSTERS are well worth looking at. Select one of these from the table below. They are all fairly BRIGHT and in the NORTHERN sky.

When submitting the JOB to the ROBOTIC TELESCOPE, give the object as an m number, e.g. m31. The telescope will know that this is the ANDROMEDA NEBULA (you may have called it this in the "OBJECT NAME" request box).

If you are obtaining the image of an OPEN CLUSTER, request TWO jobs: one with a RED filter (just "R" in the filter box) and one with a BLUE filter (just "B" in the filter box). The stars that are brighter in the B filter images are hotter and often younger.
