Messier_27.jpg
Messier 27846 viewsM 27 , aka the dumbbell nebula, in the constellation Vulpecula was discovered by Charles Messier in 1764. M27 is a large cloud of expanding gas, which is the remains of a star that expelled its outer atmosphere near the end of its lifetime. M27 is a bright object that can be seen in binoculars and is a favorite telescopic object in the Spring and early Fall. Total exposure of 1 hr 40 minutes (20 x 5 min lights;30 darks; 66 flats; AP 178 f/9 refractor; Modified Canon 50D; AP 1200 mount; guided exposures)

It is estimated to be about 800 million years old and is nearly 3.8 km (2.35 miles) deep (over twice as deep as the Grand Canyon!). Image taken using a 6" SCT at f20 using an Imaging Source DMK41AU02 camera.
Messier82_sRGB.jpg
The starburst galaxy Messier 82277 viewsThis HaLRGB image portrays the turbulent starburst galaxy Messier 82 in Ursa Major with its filamentary outflows of ionized hydrogen. This emission is suggested to be due to stellar winds caused by massive energetic young stars (as well as supernovae resulting from their death) being born at a high rate within the galaxy. Total of 18 hrs exposure with a Takahashi CCA-250 f/5 astrograph; Nights of 15, 24, 28 March 2015; 12, 13 Jan 2016; 8, 9 Feb 2016: 2015 Paramount ME, QSI683wsg, Astrodon Gen2 filters (Ha 5 nm); (Lum 16 x 20 min; Ha 17 x 20 min; R 7 x 20 min; G 7 x 20 min; B 7 x 29 min all @ - 20 degrees C), calibrated, registered, integrated, and processed in PixInsight 1.8.4.1195 (x 64).

NGC4565Large.jpg
An Edge-On Spiral Galaxy in Coma Berenices3 viewsNGC 4565, sometimes referred to as the Needle Galaxy, is an edge-on galaxy in the constellation Coma Berenices. One can see the galaxy's yellowish central core, which is divided by obscuring dust lanes running the length of the equatorial plane. Total exposure was 10 hrs 20 min taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon Gen2 filters) on a Paramount ME in Mayhill, NM on the nights of 8, 15, 16 May; 17, 18 June 2018 ( 21 x 1200 sec lights; 4 x 1200 sec R; 3 x 1200 sec G; 3 x 1200 sec B all @ -20 degrees C; 24 darks; 128 bias; 128 flats for each channel). Processed in PixInsight 1.8.5.1353 Ripley (x 64). An annotated image can be found on the Amateur Astronomers facebook page https://www.facebook.com/AmateurAstronomersGroup Sep 07, 2018
NGC_4631_RCOSf6_DarkMottleRepFinal_Large.jpg
The Whale Galaxy in Canes Venatici36 viewsNGC 4631 is found in the constellation Canes Venatici. The wedge-shape of this galaxy gives rise to its nickname, the Whale Galaxy. The starburst regions of this galaxy can be seen in the photo, which are due to intensive star formation. Tidal interactions of NGC 4627, which is seen just above NGC 4631, has been suggested as one of the reasons for the active core of NGC 4631 (as well as tidal interactions with other nearby galaxies). The small edge-on galaxy at the top of the image is PGC 3794315 (NASA Extragalactic Database). Total of 5 hr 40 min exposure taken with an SBIG STF8300c CCD camera and a 12.5 inch RCOS f/9 astrograph operating at f/6 (Astro-Physics CCDT067 reducer) mounted on a Paramount ME on the nights of 8, 15, 16 May 2018 in Mayhill, New Mexico (17 x 1200 sec Lights @ -15 degrees C; 15 darks; 128 bias; 128 flats). Processed with PixInsight 1.8.5.1353 Ripley (x64).Jul 13, 2018
IC_443_Large.jpg
Turbulent nature of the Jellyfish Nebula42 viewsFound in the constellation Gemini, the Jellyfish Nebula, also designated IC 443, is a large supernova remnant. The emission of the nebula is due to the excitation of hydrogen atoms as the rapidly expanding shell collides with the surrounding molecular gas. This hydrogen-alpha image shows the turbulent nature of the nebula as the resultant shock wave expands. Image taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon 5nm H-alpha filter) on a Paramount ME in Mayhill, NM on the nights of the 23rd, 24th January 2018. Total of 7 hr exposure (21 x 1200 sec lights @ -20 degrees C; 24 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (x 64).Jun 30, 2018

An Open Cluster and Nebula in the constellation Auriga193 viewsNGC 1931 is a relatively young open cluster surrounded by emission and reflection nebulosity (Sharpless 2-237) in the constellation Auriga. Faint red hydrogen emission can be see in the region surrounding the compact cluster/nebulosity. Sharpless 2-237 shows both red hydrogen emission and blue reflection nebulosity. Image was a total of 15 hours of exposure through a Takahashi CCA250 f/5 astrograph with a QSI683wsg camera @ -20 degrees C. (Astrodon Gen 2 filters) on a Paramount ME on the nights of 23, 30 Nov and 5 Dec 2016 and 13, 18, 19 Jan 2018 in Mayhill, NM (Lum 30 x 1200 sec; Red 5 x 1200 sec; Green 5 x 1200 sec; Blue 5 x 1200 sec; with corresponding Flats, Darks, and Bias). Processed in PixInsight 1.8.5.1353 Ripley (x64). Color calibration and RGB image stretch with PixInsight's Photometric Color Calibration and Arcsinh Stretch, respectively.Mar 30, 2018

The edge-on galaxy NGC 891 in Andromeda 288 viewsThe edge-on galaxy NGC 891 is found in the constellation Andromeda. NGC 891 is approximately 30 million light-years away and is similar in size to our own Milky Way galaxy. A prominent dust lane is seen in the plane of the galaxy with tendrils of dust seen above and below that plain. These dust tendrils may be due in part to supernova explosions. The image is a total of 11 hours of exposure through a 12.5 inch f/9 RCOS astrograph with a SBIG STF8300c CCD camera on a Paramount ME taken in Mayhill, NM on the nights of 13, 14 Oct 2016; 16 Nov 2017; 13, 15 Dec 2017, and 13, 19 Jan 2018 (33 X 1200 sec lights @ -15 degrees C; 18 darks, 128 bias; 128 flats).
