Wizard Nebula (NGC 7380)

Located only 8,000 light years away, the Wizard nebula surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer (concentrate on the blacker part of the images in the center-left area). The active star forming region spans 100 about light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the Cepheus. Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

What powers are being wielded in the Wizard Nebula? Gravitation, strong enough to form stars, and stellar winds and radiations, powerful enough to create and dissolve towers of gas.

This is a narrowband image. This image was taken by putting filters that lets through specific spectrum of light, i.e. Hydrogen Alpha (Ha), Sulfur (SII) and Oxygen (OIII). The reason why we take these images in narrowband is to ignore all the other spectrum of light, and only concentrate on the spectrum with which most of this large nebula is made. This allowed me to image this nebula on nights when Moon is up in the sky and would normally prevent me from imaging deep space objects.

Shot with Hydrogen Alpha filter as Hydrogen Alpha (30 images of 20 minutes each), OIII (Oxygen)(15 images each of 20 minutes each) and Sulfur (SII) (17 images of 20 minutes each). Total Exposure 21 hours.
