Start from Enif in Pegasus hop to stars 2, 4, 7 for direction confirm then hop to
two stars mag6 which form as an Imaginary triangle, Enif locates at the top.
M15 locates at base line of triangle close to a star mag6.
M15 can be seen in finder scope as a star mag6, quite easier than M2.
M15 appeared to me as round, small, bright nucleus and couldn't resolve any stars.
star field is quite rich in this area. when compare with red shift 3 program-tycho
catalog, the positions are quite accurate.
