The Cocoon nebula, has many names (Sharpless 125, Caldwell 19, Collinder 470), it is both an emission and reflection nebula. Located 4000 light years away in constellation Cygnus. The nebula is 12 arc minutes across or 15 light years. The dark lanes that surround nebula are part of the larger Barnard 168. Total exposure LRGB was 2 hours. 5 hours of Ha data was used to add some details to Luminance. 8 inch RC telescope QSI 683 camera, My T mount.
The ring nebula or Messier 57, is a planetary nebula in Lyra. The central star has expelled its outer layers and is in the process of becoming a white dwarf. This is a small looking object in the sky, the nebula disk has an angular size of 1.5 × 1 arcminutes. The small faint galaxy lower right of the ring is IC 1296. IC 1296 is a barred spiral galaxy, it is much farther away – an estimated distance of ~221-million light years as compared to M57’s mere 2300LY. Taken using 8 in RC telescope, QSI 683 camera. RGB exposure 240 sec each binned 2×2 Luminance was 300 seconds each, Ha data was 900 seconds and 180 seconds each total exposure time was 12hours.
NGC 7331 an unbarred spiral galaxy approx. 40 million light years away in constellation Pegasus. Several galaxies seen in the back round of this image are about 300 million light years away. The central bulge typically co-rotates with the disk but the bulge in the galaxy NGC 7331 is rotating in the opposite direction to the rest of the disk.
Shown here LRGB with a few hours of Ha to accent. Total integration time was 8 hours LRGB another 3 hours of Ha. 8 inch RC telescope, MyT mount, QSI 683 Camera, Astrodon filters.
The Pelican nebula a Ha region in Cygnus constellation located near the bright star Deneb bordering along the Cygnus wall region of north American nebula. Images shown here top down are area in Hydrogen alpha, a crop of Ha image showing Herbig–Haro object 555. Herbig-Haro object are gas jet being emitted from newly formed stars. Next image is RGB “natural colors of region. Lastly is area shown using the “hubble palette” SHO sulfur mapped to red Hydrogen to green and oxygen to blue. Total integration time is 16 hours.

Iris Nebula a bright reflection nebula in the constellation Cepheus. 1300 light years away from earth, 6 light years across. Total exposure time 5.5 hours LRGB. 8 inch RC telescope QSI 683 camera
Barnard’s Galaxy or NGC 6822 a “close” irregular barred galaxy in constellation Sagittarius. It is 7,000 light years across and “only” 1.6 million light years away. Total integration is only 2.75 hours, LRGB with some Ha to accent the nebulas of the galaxy. The largest of which is cataloged as 2 separate nebulas, the bubble nebula and the ring nebula. Personally I don’t see the resemblance. Who knows what it looks like under higher magnification. This is as seen from my 8 inch RC telescope from my semi light polluted backyard.

Bubble nebula in RGB, an emission nebula in Cassiopeia approx. 7,000-10,000 light years away. The bubble itself it formed from the stellar wind of the central star. The surrounding nebula contains the expansion of the bubble, and is also excited by the central star. Shown here in natural colors. Total integration 3.75 hours 8 inch RC telescope QSI683 camera
Now shown here with RGB stars and narrowband in “hubble” palette SHO total exposure time with full narrowband at 15 hours
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 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.
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.
