Locating guide from the book0,8° ESE of β Lyr

N, S, E and W indicate cardinal directions; combinations give a more precise direction. Greek letters identify the constellation’s guide stars. Check the route on a suitable chart.

Photographs help you recognise structures, but do not predict the view through an eyepiece. Detection depends on the sky, the object’s altitude and your instrument.
