NGC 1579 - Nebula in Perseus

NGC 1579 is often referred to as the "Trifid of the North" in that it strongly resembles the famed nebula in Sagittarius. Like the Trifid, it has prominent dust lanes at its center. It was also compared to the Trifid in that it was believed to consist of both emission and reflection regions. However, more recent spectral analysis of NGC 1579 has revealed that the red hue was not due to hydrogen being excited by the ultraviolet light of a hot young star. Rather, the color can be attributed to a high luminosity red star, LkAlpha101, its light being diffused by the surrounding nebula. At least 35 fainter Ha emitters are also located within the nebula.

NGC 1579 lies approximately 21,000 light years away. It has a diameter of 3 light years.

Celestron C11 Edge HD @ f/7

Cameras: Luminance: SBIG ST-8300 w/Baader filters
Color: Modified Canon 650D (Raw capture; ISO 1600)
Mount: iOptron CEM60; guiding with Lodestar on ONAG
Exposures: Luminance: 24 @ 5 min. through clear filter and 18 @ 5 min. through Ha filter (both binned 2x2)
Color: 18 @ 5 min.
Processing: Luminance and Ha images were focused, calibrated, aligned, and combined in CCDSoft. Color images were calibrated, aligned, and combined in ImagesPlus. A master Luminance image was produced by combining the L and Ha images. The Luminance and color images were aligned in RegiStar and the composite image was adjusted in Photoshop. Sharpening and noise reduction were done using Topaz Detail and DeNoise respecitively.
