NGC 3718

NGC 3718 in Ursa Major, the warped spiral galaxy near picture center. The spiral arms are twisted and extended likely from interaction with NGC 3729 the smaller looking galaxy at bottom of the image. The pair are only 150,000 light years apart and located 52 million light years from earth. Much further and much less detailed in this image is Hickson Group 56, 5 interacting galaxies 400 million light years distant.

Sharpless 257

Sharpless 2-254 through 2-258 are shown here in this image 254 at top of image 257 below that 256 slightly the the right of 257 and 255 the brightest at bottom. The nebula reminds me a lot of the much more photographed cocoon nebula.

NGC 2903

Imaged this last year I wasn’t happy with the result. I am much happier this go around. Shown here in natural colors. NGC 2903 is a barred spiral galaxy. Found  in Leo constellation 30 million light years away. RC8 scope QSI 683 camera toal integration 7 hours Luminance 2.5 hours each channel RGB.

Pacman nebula

NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way’s Perseus Spiral Arm. Shown here in natural color as well as the popular “hubble palette” SHO. Integration times are as follows: RGB 16 x 240 sec each channel Sulfur Hydrogen and Oxygen 22 x 900 seconds, 30 x 900 and 26 x 900 respectively. 8 inch RC telescope QSI 683 camera MyT mount processed in PixInsight.

NGC 896

IC 1795 shown here in natural colors as well as SHO. Part of heart nebula, this area looks like a fish head to many. Located 6000 light years away in the Perseus arm of our milky way galaxy. Integration time total is 45 mins each RGB binned 2×2 sulfur, hydrogen and oxygen 4 hours each.

IC 410 Tadpole Nebula

  This telescopic close-up shows off the otherwise faint emission nebula IC 410. It also features two remarkable inhabitants of the cosmic pond of gas and dust below and right of center, the tadpoles of IC 410. Partly obscured by foreground dust, the nebula itself surrounds NGC 1893, a young galactic cluster of stars. Formed in the interstellar cloud a mere 4 million years ago, the intensely hot, bright cluster stars energize the glowing gas. Composed of denser cooler gas and dust, the tadpoles are around 10 light-years long and are likely sites of ongoing star formation. Sculpted by winds and radiation from the cluster stars, their heads are outlined by bright ridges of ionized gas while their tails trail away from the cluster’s central region. IC 410 lies some 10,000 light-years away, toward the nebula-rich constellation Auriga.

Thor’s Helmet

NGC 2359 or Thor’s Helmet also cataloged as Sharpless 2-298 and Lynds Bright Nebula LBN 1041. An emission nebula in Canis Major, approx. 12,000 light years away. The nebula is approx. 30 light years across. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor’s Helmet.  Integration time 10 x 240 seconds each channel RGB, Ha 15 x 900 seconds, OIII  36 x 900 seconds. Total time 14.75 hours 8 inch RC telescope, QSI 683 camera.

NGC 225

 

NGC 225 is an open cluster in the constellation Cassiopeia. One of it’s stars, the variable star V594 Cas, illuminates the blue reflection nebula van den Bergh (vdB) 4, which also cataloged as LBN (Lynds Bright Nebula)604. The dark nebula is cataloged as LDN (Lynds Dark Nebula)1302. Total integration is RGB binned 2×2 8 x 240 seconds each channel, Luminance 30 x 300 seconds.  Total of 4 hours LRGB 8 inch RC telescope QSI 683 camera
