Crescent Nebula NGC 6888

NGC 6888 or the Crescent Nebula an emission nebula in Cygnus. Located about 5000light years from earth. This nebula is formed by the fast stellar wind from a Wolf-Rayet star colliding with and energizing the slower moving wind ejected by the star when it became a red giant. It is a rather faint object located about 2 degrees SW of star Sadr. Images shown here top image is SHO. Bottom image is a bi color image HOO with a few tweaks. Total integration is only 8 hours. I think it could be better with more time on target but the clouds are relentless this year.

Barnard 143 dark nebula

Barnard 143 an absorption nebula located in Aquila. The dark threads of gas dim some stars and completely black out others. This dark nebula  is about the size of a full moon, can be seen with a set of binoculars against the back round of countless stars. I didn’t invest much time on this since it is really just stars and absence of stars due to the dust, since there is no real structure to the dust. As you can see on the border of the dust where some light peaks through the color of star light is changed. These stars appear more red than the other average star in area.1 night lrgb 4.5 hours.

NGC 6791

An open cluster in Lyra constellation, estimated at 8 billion years old. 13,000 light years away from earth sits this metal rich cluster. Kepler Mission space craft launched in 2009 by NASA. Its mission is to discover extrasolar planets. First light from this mission released in April 2009 showed NGC 6791.  Kepler-19, discovered from Kepler data, is located approximately 5 arcminutes Northwest of NGC 6791. There are at least 2 confirmed extrasolar planets orbiting Kepler 19. Image taken during full moon July 2017. Total integration 5.5 hours LRGB.

Messier 27

Messier 27 commonly called the Dumbbell nebula. This is a  planetary nebula in the constellation Vulpecula, at a distance of about 1,360 light-years. A planetary nebula is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from old red giant stars late in their lives. The central star is a white dwarf. This image shows M 27 as a bi color image Hydrogen is Mapped to red and Oxygen is used for both green and blue. Taken during a full moon the outer shell can be captured in narrowband even during the full moon using long exposures. Total exposure time here is 12 hours using 15 minute sub frames. 8 inch RC telescope QSI 683 camera astrodon filters MyT mount. Processed using PixInsight.

Added RGB data to give RGB stars and a more natural look. I only had 25 minutes of each channel RGB. HOO data added to give final image. Entire image including RGB taken during 80-100% full moon.

NGC 7129 and NGC 7142

NGC 7129 center/left  and NGC 7142 far right of image.  In the foreground, dusty nebula NGC 7129 is about 3,000 light-years distant, while open cluster NGC 7142 is likely over 6,000 light-years away.In fact, the pervasive and clumpy foreground dust clouds in this region redden the light from NGC 7142, complicating astronomical studies of the cluster. Still, NGC 7142 is thought to be an older open star cluster, while the bright stars embedded in NGC 7129 are perhaps a million years old.  The telltale reddish crescent shapes around NGC 7129 are associated with energetic jets streaming away from newborn stars. Surprisingly, despite the dust, far off background galaxy can be seen. Total integration time is 5.5 hours 50 minutes each RGB the rest is luminance. 8inch RC telescope QSI 683 camera, astrodon filters, MyT mount

Messier 13

Located in constellation Hercules 25100 light years away, comprised of some 300,000 stars. Messier 13 is 145 light years across. It is just barely seen with the naked eye on a dark clear night. A small galaxy IC 4617 is seen here on the lower left side of M13. Exposure time is 3 hours, 30 mins each RGB and 1.5 hours luminance taken during a full moon. 8 inch RC telescope QSI 683 camera MyT mount.

Hercules super cluster

Hubble has the deep field I have Hercules super cluster.  Image centered on NGC 6050 the cluster is located an estimated 500,000,000 light years away.  There are always some distant fuzzy galaxies in the back-round of many galaxy images. This however is intentionally imaged. Through my 8 inch telescope there is little detailed structure. The overall shape is there, even managed to get a blue gas jet coming off IC 1182 (slightly to left and down from center) total exposure time is 8 hours. 1 hour each RGB 5 hours of luminance. 8 inch RC telescope, QSI 683 camera, Astrodon filters, MyT mount. Processed in PixInsight.

Veil Nebula

A work in progress, this is a portion of the veil nebula in Cygnus. A super nova remnant, and probably one of my favorite objects to work on. There are so many little twists and turns of the gasses its a lot of fun to process this object. Work incomplete just happened upon some cloudy nights and had something to play with. shown here in the popular “Hubble palette” SHO.

Larger portion of veil, this is the western portion of veil nebula. Shown here as a bi color image HOO hydrogen is red oxygen is used for both blue and green. The green channel is slightly subdued to show more of a blue color. Still a work in progress I just barely had enough images to put together still has a lot of noise in image. This is a 2 panel mosaic. image integration is unbalance between the 2 parts of mosaic oxygen is 14 subs on 1 side 6 on the other hydrogen is 14 on one side and 7 on the other. All things being equal it looks ok so far. more to come if the clouds ever part.

NGC 5466

NGC 5466 a globular cluster in the constellation Boötes. Located 51800 light years from earth. A fairly dim cluster at magnitude 9.There are a couple dim distant galaxies in the frame unknown what distance these are. My capture software (skyx pro) gives me a magnitude 17 for all of them, however I cannot find a distance. Exposure was during full moon. Exposure time was 7 hours. 4 hours Luminance 1 hour each RGB.

Messier 101 Pinwheel Galaxy

Messier 101  “Pinwheel Galaxy” a face on spiral galaxy in constellation Ursa Major 21 million light years away. Comparable in size to our milky way galaxy its diameter is an estimated 170,000 light years across. Notable for its high population of H II regions, many of which are very large and bright. Luminance layer from 8 inch RC telescope color and Ha mixed from 2 systems 6inch Newtonian and 8 inch RC. Fairly long exposure time on this most of it is in color from the 6 inch Newtonian.
