M46M47NGC2423inPuppis.jpg
Open Clusters M 46, M47, and NGC 2423 in Puppis705 viewsThe open clusters Messier 46, Messier 47, and NGC 2423 are found in the constellation Puppis embedded in a rich field of Milky Way stars. The small planetary nebula NGC 2438 that appears to be in M 46 is actually not associated with the cluster. M 46 was discovered by Messier in 1771. Smyth describes it as a “A noble, but rather loose assemblage of stars” (Smyth and Chambers, A Cycle of Celestial Objects, 2nd Edition, 1881, Oxford) whereas Webb describes it as a “Beautiful circular cloud of small stars” (Webb, Celestial Objects for Common Telescopes, 4th Ed, 1881, Longmans, Green, and Co ). William Herschel observed the small planetary nebula NGC 2438 in 1786. M 47 was also discovered by Messier in 1771 but not intermediately attributed to Messier due to a mathematical mistake in his coordinates. The cluster was described by Smyth as “a very splendid field of of large and small stars” (under the entry 38 H VIII) and Webb as a “Grand broad group, visible to the naked eye”. This wide field picture was taken with a Takahashi FSQ106ED with focal reducer (f/3.6), Canon 60Da DSLR camera (2.32 arcsec/pixel), and an Astro-Physics 1200 mount on 15 March 2015 in Mayhill, NM.. Total exposure of 1 hour (4 x 15 min lights, dithered; 12 darks; 128 bias; 64 flats); Baader/Astro-Physics guider system; Image acquisition with MaxIm DL; Calibration, alignment, integration, and image processing with PixInsight 1.8.3.1123.
M57finalsmall.jpg
The Ring Nebula in the Constellation Lyra174 viewsM57, the ring nebula, is found in the constellation Lyra. M57 is a planetary nebula, which is an expanding shell of gas ejected from a star in the later stages of its evolution. The image captured the outer halo structure of M57 as well as the galaxy IC 1296 (see annotated image on the Facebook page). Image is a total of 9 hr 20 min exposure taken through a 12.5” RCOS f/9 astrograph at f/6 (Astro-Physics CCDT67 reducer) with a SBIG STF8300m CCD camera on a Paramount ME on the nights of 18, 19, 22 May 17, 19 June 2020 in Mayhill, NM (13 x 1200 s lights, 5 x 1200 s blue, 5 x 1200 s red, 5 x 1200 s green all at -15 degrees C). Processed in PixInsight 1.8.8-6 Ripley (x64).

The_Soap_Bubble_sRGB.jpg
The Soap Bubble in the Nebulosity of Cygnus990 viewsThe Soap Bubble Nebula, or PN G755.5+1.7, is found in the constellation Cygnus. The Soap Bubble is likely a symmetric planetary nebula, which is the expanding shell of ionized gas ejected from a star late in its lifetime. The faint nebula was discovered relatively recently in 2008 on photographs of the Cygnus region. Image was a total of 17 hr 20 min exposure taken with a Takahashi CCA-250 f/5 astrograph with a QSI683wsg camera (Astrodon Gen2 H-alpha filter 5 nm; O[III] 3 nm) on a Paramount ME on the nights of 2, 4, 5, 21, 25, 26, 29, 30 October 2016 in Mayhill, NM (26 x 1200 sec H-alpha lights @ -20 degrees; 26 x 1200 sec O[III] lights @ -20 degrees; 23 darks; 128 flats of each filter; 126 bias; processed in PixInsight 1.8.4.1195; color assigned in SHO-AIP Red = 90 % H-alpha; G = 10% H-alpha and 100% O[III]; Blue = 100% O[III]).
NGC_246.jpg
NGC 246 (The Skull Nebula)915 viewsNGC 246 is a small planetary nebula in the constellation of Cetus. The nebula was discovered in 1785 by William Herschel and gets its nickname due to its resemblance to a human skull. NGC246’s central star, is a white dwarf that is entering its final phase of evolution becoming a hot white dwarf. This image was taken on Oct 23, 2016 with an 8" TPO RC telescope, Canon 60Da camera, on a Celestron CGE Pro mount. Stacked with Nebulosity 4 and edited with PixInsight 1.8

M76 - The Little Dumbbell909 viewsMessier 76 was discovered in 1780 by Pierre Méchain and cataloged by Charles Messier that same year. It wasn't until 1918 that M76's true nature as a planetary nebula was discovered by Herber Curtis. Located some 2,500 light years away in the constellation Perseus, M76 it is one of the faintest objects in the Messier catalog at magnitude 10.1. This image was taken from Alamogordo NM using an Astro-tech 130EDT f7 refractor and Atik 314L+ monochrome camera (130 min) using Ha, Hb and OIII signals.
Messier_27_in_the_constellation_Vulpecula_sRGB.jpg
Messier 27 in Vulpecula782 viewsMessier 27, which was discovered in 1764 by Charles Messier, is a bright planetary nebula in the constellation Vulpecula. The nebulosity is due to the expulsion of a star's outer layers in the later stages of its life and is illuminated by the stars intense radiation (blue star in the center of the nebula). Image was taken in Mayhill, NM on the nights of 14, 15, 16, 17 September 2015; total of 5 hrs 40 min exposure through an Astro-Physics 178 mm f/9 refractor with field flattener and an SBIG STF8300c camera with OAG (ST-i) on an Astro-Physics 1200 mount (17 x 20 min lights dithered @ -15o C; 33 darks; 128 bias; 128 flats); image acquisition with MaxIm DL 6.10 and processed with PixInsight 1.8.4.1170. Processing included Bayer drizzle, a Synthetic Luminance, and Multiscale Processing.
Helix_Nebula.jpg
Helix Nebula1476 viewsThe Helix Nebula (NGC 7293), aka Helical Nebula or Sunflower Nebula, is a planetary nebula found in the constellation Aquarius. Despite it's designation as a "planetary" nebula, it has no relation to a planet. The term planetary nebula came from the "appearance as a planetary disk" in early telescopes. Planetary nebula are indeed the expelled gaseous remains of aging stars. The image is a total exposure of 1 hr 40 min (20 X 300 sec) taken with a Takahashi E-180 and Canon 20Da DSLR camera.
M_97.jpg
Messier 97, the owl nebula1346 viewsMessier 97, aka the owl nebula, in Ursa Major is described in Admiral W. H. Smyth’s A Cycle of Celestial Objects (2nd Ed, 1881) as a “large planetary nebula, or globular collection of nebulous matter.” M97 has a three-shell structure; the red color of the Ha emission of the second shell is visible in the image. Image is a total of 8 hr exposure taken with an Astro-Physics 130mm f8 refractor and SBIG SR2000xcm on an AP 1200 mount (24 x 20 min lights, 30 darks, 64 flats, 64 flat darks, 64 bias) calibrated in Images Plus 5.0; color balance in PixInsight 1.8; Photoshop CS6
