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 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
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.
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.

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 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” 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.
Messier 51 commonly called the “Whirlpool Galaxy”. A beautiful example of an interacting grand design spiral galaxy. Located in the constellation Canes Venatici, M 51 is approx. 23 million light years away. Imaged here in natural colors with Ha added, total exposure time is 8 hours.
Messier 16, the “Eagle Nebula” a young open cluster of stars in constellation Serpens. Contained in this image is the “pillars of creation” made famous by Hubble Space Telescope. The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula is approximately 9.5 light-years or about 90 trillion kilometers long. Image shown here in SHO. 9 hours of exposure time on a 8 inch RC telescope.
Messier 95 in LRGB 4.5 hours of exposure. A barred spiral galaxy, 38 million light years away in Leo constellation.
