![]() Scientists believe there are 700 stars at various stages of evolution within the nebulosity you see in the photo (close-up crop below). The Orion Nebula (M42 or NGC 1976) is the most easily visible and closest region of massive star formation to us. Guided using Orion Mini 50mm Guide Scope with ZWO ASI120MC-S color CMOS using PHD2 software. Hardware: Tele Vue-85 with Tele Vue 0.8x Reducer/Flattener (TRF-2008) with stock Canon 70D DSLR. ![]() The Great Orion and Running Man Nebulae by flickr user Vesselin Petkov. ![]() A giant O-type star pumps out massive amounts of ultraviolet light that energizes the gasses in the nebula and causes them to emit light in their distinctive characteristic colors. “Lagoon Nebula” (M8 or NGC 6523), in the constellation Sagittarius, is a giant star-forming region with an open cluster of stars embedded within. Processing with PixInsight and Photoshop. Imaging: 40 x 180” lights (Temperature -5C offset 50 gain 101) and no calibration frames from Cairns, Australia in Bortle Scale (1 best, 9 worst) 5 skies. Hardware: Tele Vue-85 with Tele Vue 0.8x Reducer/Flattener (TRF-2008) into ZWO ASI533MC Pro color CMOS camera using AstroImager for Mac software. Lagoon Nebula by flickr user Vesselin Petkov. At the top left is open cluster NGC-3324. It is the bright star near the tip of the triangle structure in the center of the image. The most energetic star in the complex, double-star Eta Carinae, is thought to be on the verge of a supernova explosion. The dark shapes entwined in the nebula are remnants of clouds of cool gas and dust from which the first giant stars in the nebula were born. Radiation has ionized regions in the nebula and caused them to glow – such is the telltale reddish glow from ionized hydrogen atoms recombining with electrons. The shape of the nebula is sculpted by shockwaves and radiation pressure from many supernovae explosions. The “Eta Carinae” or “Great Carinae” Nebula (NGC-3372) is located in the southern sky constellation of Carina (ship’s keel). Imaging: 42x 180” lights (ISO 1600) and no calibration frames from Cairns. Hardware: Tele Vue-85 with Tele Vue 0.8x Reducer/Flattener (TRF-2008) with stock Canon 6D DSLR. The stars around the nebula are an open cluster.Įta Carinae Nebula by flickr user Vesselin Petkov. The outer blue zone is starlight reflecting off of dust. ![]() A single giant star in the center of the nebula powers the red glow of hydrogen gas surrounding it. “Trifid Nebula” (M20 or NGC-6514) was named by John Hershel (1792-1871) who dubbed it the “Trifid” - from Latin for three parts or lobes - based on his telescopic observations of the divisions in the central part of the object. ![]() Imaging: 32 x 300” lights (Temperature -5C offset 5 gain 10) and no calibration frames from Cairns, Australia in Bortle Scale (1 best, 9 worst) 5 skies.
