Description

Emission nebula glow red because of an HII region becoming ionized by nearby stars. The electons "freed" by this ionization are continually absorbed and reemitted causing it to glow red. Dark nebulas are cool clouds of dust and molecular hydrogen that can be seen when silhouetted against a bright background (ie. the Horsehead nebula). Reflection nebula are areas in which material that contain dust is reflected from nearby stars. Because of the shorter wavelength of light this "dusty" area appear blue.

Description

Sharpless 157, also known as the Lobster Claw Nebula, is a bright emission nebula in the constellation Cassiopeia. It lies just south of the better-known Bubble Nebula (NGC 7635). Within this image are a few other objects. Planetary Nebula PLN 110-0.1 is located near the center of the upper-right quadrant. The bright nebular spot near the center of the image is Lyn's Bright Nebula 537 (LBN537), also known as Sharpless 157a. The small cluster of stars just above the bottom pincer is Markarian 50 and the bright cluster of stars located above the top pincer is open cluster NGC 7510.

Description

The Elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396 – an ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown above is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star that is just to the west of IC 1396A. (In the Figure above, the massive star is just above the top of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.

Description

Image of the Helix Nebula is 17 x 5 min exposures at ISO 400 with Canon 450D, AT106 on the Atlas. Manually guided with a AT65 piggybacked on the 106. Images stacked and calibrated (15 dark frames, 15 flat frames) with Maxim DL, processed with Photoshop CS5, Noise Ninja and GradientXTerminator. Image captured at Tamalco Boat Ramp on Carlyle Lake, in southern IL about 50 miles east of St. Louis, MO. Excellent dark site for the River Bend Astronomy Club. Thank you for your kind consideration.

Hubble palette image of NGC7635 with LRGB images used to colorize the stars. Exposures were 900s 1x1 binned for the SII, Ha, and OIII filters and 480s 1x1 binned for the L, 300s 2x2 binned for the R and G, and 480s 2x2 binned for the B. The exposures were captured using Nebulosity 2 and guiding using PHD. Image processing using AIP4WIN, DeepSkyStacker, Nebulosity 2, PhotoShop, and PixInsight LE.
