Ahh - the old 'coathanger'. It is always a marker for summer observation sessions. It is visible to the naked eye in reasonably good skies, although at that scale it looks like a little fuzzy line rather than a 'coathanger'.

I like the use of the Coathanger as a calibration tool for photometry devices as its stars cover a relatively narrow range of magnitudes, hence why Brocci identified it as a valuable cluster
