The open cluster in the center of IC 1805 is Melotte 15 that contains several extremely large stars whose intense radiation ionizes the hydrogen gas in the region. To the lower left of IC 1805 is the bright nebula NGC 896. To the mid-right of IC 1805 is the open cluster NGC 1027. The image encompasses a vast region with the image scale being approximately 3.1 x 2 degrees.

California_Nebula__NGC_1499.jpg
The California Nebula930 viewsNGC 1499, aka the California Nebula, is a large emission nebula in Perseus. It is about 2.5 degrees in length and has a very low surface brightness, which makes it somewhat of a challenge to observe visually. The image was taken with a Canon 60Da DSLR and a Takahashi FSQ106ED telescope with focal reducer (f/3.6 FL = 385 mm) on an Astro-Physics 1200 mount. Total combined exposure was 5 hrs (20 x 15 min guided and dithered lights; 12 darks; 128 bias; 64 flats) taken over three nights (Oct 23rd , 27th , 28th 2014). Image acquisition with MaxIm DL6.07 and calibration, registration, and integration with PixInsight; processing with PixInsight 1.8.3.1123 Ripley (x64) and Adobe Photoshop CC.
MultiscaleHaLumFinal.jpg
Messier 82828 viewsThis combined Ha and Luminance image shows the 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 supernova resulting from their death) being born at a high rate within the galaxy. Total of 9 hr 20 min exposure with a Takahashi CCA-250 f/5 astrograph; Nights of 15, 28 March 2015, 12, 13 Jan 2016, 8, 9 Feb 2016; 2015 Paramount ME, QSI 683wsg, 5 nm Astrodon Ha filter (Lum 11 x 20 min @ - 20 degrees C; Ha 17 x 20 min @ - 20 degrees C), calibrated, registered, integrated, and processed in PixInsight 1.8.4.1195.

ASIC410.jpg
IC 410 and the Tadpoles in Ha760 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the “Tadpoles”, are moving away from the center of the nebula. The image is a Ha image, which shows the extent of the hydrogen emission in the region. The image was taken with a Takahashi CCA-250 astrograph and the QSI683wsg camera (SBIG ST-i guider) on a Paramount ME. The image is a total of 8 hours exposure (24 x 20 min lights @ -20 degrees C, dithered; 21 darks; 126 bias; 128 flats), acquired with MaxIm DL 6.07, and processed with PixInsight 1.8.3.1123 Ripley (x64). Ha filter was an 5nm bandwidth 31 mm Astrodon Gen 2 filter.

Emission nebula IC 410 and the Tadpoles in HaRGB784 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the “Tadpoles”, are moving away from the center of the nebula. Picture is a HaRGB image taken with a Takahashi CCA-250 f/5 astrograph and a QSI683wsg camera (SBIG ST-i guider) on a Paramount ME. The Ha channel (used as Luminance) was blended with the RGB synthetic luminance (80:20, respectively) to give a more natural star color (Pixel Math). The image is a total of 11 hours exposure (24 x 20 min Ha, 3 x 20 min each R,G, and B, all binned 1x1 @ -20 degrees C, dithered;), acquired with MaxIm DL 6.07, and processed with PixInsight 1.8.3.1123 Ripley (x64). Ha filter (5nm bandwidth), R, G, and B were 31 mm Astrodon Gen2 filters.
The_Crescent_Nebula_Ha5xOIII.jpg
The Crescent Nebula in Ha and O[III]771 viewsThe Crescent Nebula (NGC 6888) is an emission nebula found in the constellation Cygnus.
