This is a combination of 20 images, each of 120 seconds The images were taken with a Alta-U9 attached to an Televue 85mm F/7 telescope. Each of the images was corrected with a dark frame and a flat field.

A Hydrogen Alpha filter was used.

The area in the center is known as the butterfly nebula (which is different than the Butterfly Planetary Nebula)
