M27, also known as The Dumbbell Nebula is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. It was the first such nebula to be discovered, by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and diameter of about 8 arcminutes, it is easily visible in binoculars and is a popular observing target in amateur telescopes.

Here, NGC 884 and 869 are shown. Commonly reffered to as "The Double Cluster", these two Open Star Clusters are reletively close to Earth within our Milky Way. The two lie in the constellation of Perseus. The Double Cluster is a naked eye object for some depending on age and location. Personally, NGC 884 and 869 are two of my favorite objects to look at. Because they are so large, most telescopes have to use low power magnification to veiw them, which makes the young hot stars really POP out from the background sky. Each star can be resolved, looking like a cloud of diamonds against the charcoal gray of the night sky.

Open star cluster NGC 559 in Cassiopeia.

3,700 light years from Earth and at over 2 billion years old.

It's estimated to contain between 50 - 100 stars within the cluster. It can be seen with a medium to large telescope, big binoculars also if your lucky enough to have very dark skies.

I made the mistake of not guiding. As I thought I wouldn't need it as I was only taking 50 second exposures. My polar alignment wasn't the best and my collimation was a little out, noticeable in some elongated stars. It shows up more as I've cropped it quite heavily. The bigger you're reflector the more often it needs collimating I find.

Taken a couple of nights ago from the back garden, a view of the star field at the end of the W shape of the constellation Cassiopeia, including the green glow from the gas surrounding Comet Jacques. Also visible is the background of stars in our Milky Way galaxy and two open clusters of stars. Messier 52 can be seen in the top centre and NGC 7789 to the lower right. There are two faint red patches of light - coming from glowing clouds of hydrogen, NGC 7822 close to the left and about a third of the way up from the bottom and to the top right of the cluster Messier 52 is NGC7635, also known as the bubble nebula.

In total there were 40 exposures of 20s used, combined in DeepSkyStacker and the image corrected in FitsWork to flatten the background.

- www.kevin-palmer.com - A few weeks before perihelion, I went out to see and photograph Comet ISON (C/2012 S1). Astronomical twilight started only 20 minutes after the comet was high enough above the horizon. I'm glad I was able to see and photograph it because 2 weeks later, the comet burnt up by the sun. On this night ISON could just barely be seen as a fuzzy green point of light in binoculars. Through an 8" dobsonian telescope it looked fairly small but beautiful. Since the comet was in Virgo, several small galaxies can also be seen in this picture. This was shot with a 135mm lens and is made up of 15 2-minute exposures, plus bias and dark frames. An iOptron Skytracker was used to track the stars. Spring Lake State Wildlife Area where this was taken has moderately dark skies and a low horizon to the southeast, so it was a great place to view the comet.

Thank all for your visit and awards.

The Cocoon Nebula in Cygnus is a star-forming region with a diameter of about 15 light-years and lying several thousand light-years from Earth.

The nebula itself is powered by the bright star visible near it's center and contains a cluster of young hot stars. Framed against an extremely dense star field, it seems to punctuate the end of a sinuous 2 degree long dark nebula cataloged as Barnard 168. With the Cocoon glowing at magnitude 7.2, the blackness of the dark nebulae surrounding it makes for a wonderful contrast to the Cocoon itself and results in a spectacular view in larger instruments.

Image Details: The attached images were taken Jay Edwards on June 17, 2018 simultaneously using (left) an 80mm f/6 triplet apochromatic refractor (ED80T CF) connected to a Televue 0.8X field flattener / focal reducer and (right) a vintage 1970 8-inch, f/7 Criterion newtonian reflector. The 80mm was piggybacked on the 8-inch, and the scopes utilized twin (unmodded) Canon 700D / t5i DSLRs.

These optics were tracked using a Losmandy G-11 mount running a Gemini 2 control system and guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor which itself was piggybacked on top of the 80mm apo.

The attached composite image was constructed using, relatively speaking, extremely small stacks of short 1 minute sub-exposures, and consists of only 20 minutes total exposure for the 80MM shot & 30 minutes for the 8-in image (both in addition to applicable dark, flat & bias frames), and thus contains far more noise than we would normally produce.

Processed using a combination of DeepSkyStacker, PixInsight and PaintShopPro, as presented here it has been re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.

Given such short exposures I was intrigued by the results and look forward to taking deeper shots when this object is once again conveniently placed in our evening skies next summer.

A wider field image of this object taken in August of 2016 and showing the extent of the dark nebula in this region can be found at the link attached here: www.flickr.com/photos/homcavobservatory/30655875511/in/al...
