Messier 15 located in the constellation Pegasus is one of the densest planetaries known. Located northeast of the center of the globular is a challenging object to find, planetary nebula Pease-1. This was the first nebula discovered within a globular by Francis Pease in 1928.
Follow the directions by Doug Snyder to locate this planetary which very near the core of M15 — you’ll need a high power eyepiece, an O3 filter, dark skies, and large scope to observe it directly.
