The_Flaming_Star_Nebula.jpg
The Flaming Star Nebula855 viewsThe Flaming Star Nebula, IC 405, is located in the Constellation Auriga. The nebula is illuminated by the variable star AE Aurigae that is slowly passing thru the nebula but in fact did not condense from the surrounding nebula. The image acquired with a Canon 20Da DSLR (ISO 800) and a Takahashi E 180 astrograph. Total exposure time of 2.5 hrs (30 X 300 seconds lights calibrated, aligned, stacked, and stretched (DDP) in Images Plus 3.80 and further processed in Adobe Photoshop CS4).
NGC6910_L.jpg
A Young Open Cluster in a Nebulous Complex 410 viewsThe open cluster NGC 6910 is found in the nebulous emission complex IC 1318, which is located in the constellation Cygnus. As NGC 6910 is near the galactic plane, there is a significant amount of interstellar dust in the area. Indeed, the blue spectroscopic star HIP 100548 (aka SAO 49563) is rendered yellowish white due to the light scattering by the interstellar dust. Estimated distance of the star cluster and nebula is 2,000 to 5,000 light years. Image was taken with a 12.5 inch at f/9 RCOS astrograph with a SBIG STF8300c CCD camera on a Paramount ME in Mayhill, NM on the nights of 4, 5, 21, 25, 29, ant 30 Oct 2016. Total of 14 hr 20 min exposure (43 x 1200 sec lights at -15 degrees C; 18 darks; 128 bias; 128 flats); image acquisition MaxIm DL 6; calibration, registration, integration, and processing in PixInsight 1.8.4.1195 Ripley (x64)

An Open Cluster and Nebula in the constellation Auriga152 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).

The edge-on galaxy NGC 891 in Andromeda 242 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).

The Planetary Nebula Messier 27 with O[III] Envelope 220 viewsThe planetary nebula Messier 27 is found in the constellation Vulpecula, which was discovered in 1764 by Charles Messier. The nebula is approximately 815 light-years away. The outer Oxygen envelope was captured using an O[III] filter. The image is a total of 12 hr exposure taken through three different telescopes: 12.5 inch f/9 RCOS astrograph with a SBIG STF8300c CCD camera (Paramount ME); Astro-Physics 178 f/9 with a SBIG STF8300c CCD camera (Astro-Physics 1200); and a Takahashi CCA-250 f/5 with an QSI683wsg CCD camera (Astrodon 3nm O[III] filter) on the nights of 14, 15, 16, 17 Sept 2015; 15 June 2016; 16, 17, 23 Oct 2017 in Mayhill, NM (13 x 1200 sec Lights at -20 deg C; 24 Darks, 128 Bias; 128 flats).
