M15, a Globular Cluster in the Constellation Pegasus

This is one of the "better" globular clusters that is visible from the northern hemisphere. With a total magnitude of 6.2, this cluster is located just off to the west of the head (or nose) of the winged horse Pegasus. M15 is also one of the oldest and most densely packed globular clusters in the Milky Way galaxy.


Photographed under moderately bright skies (light pollution) using a 5 inch aperture, f/7.8 telescope and a Sony NEX-5R digital camera (ISO 3200, a stack of ninety-eight images each exposed for 10 seconds, producing a total exposure integration time of sixteen minutes and 20 seconds). Image selection, registration, integration, and adjustments done with PixInsight v01.08.00.1023 RC7 with final tweaks in Photoshop CS5 and Apple's Preview application.
