Object in the constellation Pegasus.

Globular clusters orbit the edge of our milky way galaxy and where formed 13 billion years ago.

Trying f10 high resolution imaging again with my 11 inch scope so decided to start with a nice easy object. Used exposures of 150 seconds.

LRGB image with 3 hours and 20 minutes of data. 38 x Lum, 14 x Red, 14 x Green, 14 x Blue 2.5 minute exposures.
