Details:
These images have been acquired over some period of time throughout the year. In order, the pictures are as follows: The Dumbbell Nebula, the Whirlpool Galaxy, the Southern Pinwheel Galaxy, and the Bubble Nebula.
The total exposure time for all images added together is around 2 hours. The bubble nebula, dumbbell nebula, and whirlpool galaxy used the filters iprime, gprime, and rprime, with darks applied. The southern pinwheel galaxy used the red, green, blue, and Halpha filters with darks and flats applied.
Enjoy! I turn 14 on January 3rd, so I am going to post a few more before new years.
