M51, also known as the Whirlpool Galaxy, is a spiral galaxy located in the constellation Canes Venatici. It is approximately 23 million light-years away from Earth and has a diameter of about 100,000 light-years. The galaxy is named after its distinctive spiral arms that resemble a whirlpool.
M51 is a popular target for astronomers and amateur stargazers due to its brightness and proximity to Earth. It is also a prime example of a grand design spiral galaxy, with well-defined spiral arms that are thought to be caused by density waves in the galaxy's disk.
The Whirlpool Galaxy is also notable for its interaction with a smaller companion galaxy, NGC 5195. The two galaxies are connected by a bridge of gas and dust, and their gravitational interaction has caused a burst of star formation in the Whirlpool Galaxy's outer regions.

This was a tough shot to get. Between light pollution, moonlight, and clouds moving in and out not in accordance to the weather forecast I felt lucky to be able to pull any kind of image from the data. Still I like the painterly quality it has taken on. More like something Whistler would have painted in a nocturne when he was painting his mother.

Planetary nebula HFG1 (PK 136+05)
HFG1 is an old, faint, and thus rarely imaged planetary nebula in Cassiopeia. Its most distinctive feature, the blue bowshock, results from this ball of expanding gas bowling through the interstellar medium at between 29 and 59 kilometers per second, leaving behind a trail of gasses. A planetary nebula forms when a sunlike star reaches the advanced age where it first becomes a bloated red giant star, and then throws off the star’s outer shell of gasses when the core collapses to form a white dwarf star. In the case of HFG1, the central white dwarf star V664 Cas is accompanied by a smaller star that is so close it completes each orbit in only about 14 hours. HFG has expanded for approximately 10,000 years, to the point where the nebula is about one lightyear across.

Description:
High in the northern hemisphere summer sky our home galaxy, the Milky Way, runs through the constellations Cassiopeia (left side), Cepheus (centre) and Cygnus (right side).
This area of the sky is riddled with glowing red clouds of hydrogen gas, numerous star clusters, and areas of dark foreground gas that obscures the light of millions of stars beyond.
Just a little above and to the right of centre is the bright circular red gas cloud IC 1396. For a close-up view of this nebula made with a 400 mm lens in August 2015, click here:

The photo is of the visitors at the Frido Kahlo exibition, as the title says, the slow shutter speed rendering the "abstraction"; the projected form on the wall, the red (pink) band and the moving darker forms of the visitors around the yellow form serving as frame in frame, or #subframing; with the projected colors amphasizing the red and the yellow, caught during exposure, among the many colors she used so skillfully.
I decided to capture and add some Ha filtered subframes to my M78 from January 2015.

NGC 6910 is an open star cluster set amidst clouds of gas and dust near the bright star Sadr in the constellation Cygnus.
Subframes for this image were accumulated over 4 different nights, some under dark skies near Goldendale, WA and others from within Seattle city limits. RGB data for the stars was combined with narrowband data for the gas and dust, with Ha assigned to R. In an effort to maintain a "natural" appearance, only modest amounts of SII and OIII data were added to the G and B channels, respectively.

130 degrees of the northern portion of our home galaxy, the Milky Way, and some 80,000 stars, are seen in this wide angle image, running from the constellation Cepheus at left, through Cygnus and Aquila, to Scutum at right. The Milky Way bulges noticeably at the right side, toward the centre of the galaxy in Sagittarius (out of view to the right).
A little left of and below centre is the shocking pink, distinctively-shaped North America Nebula in the constellation Cygnus. For a telephoto view of this nebula made with a 300 mm lens on the same night, click here:

A quote by Jung about exploring the Psyche.. I think it applied here too, at least it was in my head getting this view. Another trip to the river , its a long drive to this place and trying to time my original idea hasn't worked out in about just over a month.
Eight feet up a vertical rock wall to stand on a two foot square ledge with another sixty foot drop to the rocks and river below with a pack and heavy tripod. Thankfully the rocks have ledges that stick out and I could grab onto the trestle uprights to hold on once I got up there so this was from inside the trestle bridge, interestingly it was the last shot I took before I went to climb back down and leave.
Will I go back for the original shot... I don't know for now, maybe this is why I kept going back and just didn't know it. We'll see.

M13 Great Globular Cluster in Hercules
Had a few cloudless hours to grab an easy target. It is the first DSO I have imaged since November. Either my sky conditions have really deteriorated since November or there were some high thin clouds. Either way it was good to give the gear a run.
I tried something different and shot 200 Luminance filter subframes only 5 seconds each. I combined this with some RGB I shot in 2013 from my QHY23M and AT65. The large number of subframes really seemed to produce a much cleaner image. In a few months when it is clear again I will give 100+ subs a try again

At the center of this image is M 100, a face-on spiral that is part of the Virgo Cluster of galaxies. It is located in the constellation Coma Berenices. The distance to it is about 55 million light years -- the same as the rest of the Virgo Cluster. It is also known as NGC 4321.
To the right of it in this image (but south of it on the sky) is another spiral galaxy, NGC 4312. The Cosmicflows-2 catalog (Tully, et. al., 2013) puts the distance to this galaxy as 37.2 million light years -- significantly closer to us than M 100. It is also an edge-on galaxy, giving it a more flattened appearance.
This is a stack of 20 6 min exposures taken from my Bortle 8/9 backyard in Long Beach, CA. I used a Celestron Edge HD 925 at f/2.3 with Hyperstar lens and an Atik 314L+ color CCD camera with a Baader light pollution filter. Preprocessing of subframes in Nebulosity; registration, stacking, and processing in PixInsight; final touches in Photoshop.
This image shows two groups of galaxies. You might recognize Stephan's Quintet, the galaxies near the lower left corner, as the conversing angels in the movie “It’s a Wonderful Life”. 😀 The Deer Lick Group of galaxies, with NGC 7331 as its largest member, is near the upper right corner.
Telescope: Celestron Edge HD 8 at f/7

Actually two interacting galaxies, it's the most irresistible spring imaging target. Here I have aimed for the best image I can do from my red zone location using my portable gear. We had 4 clear nights in a row and I used each one to collect 2 to 3 hours of decent data. All captures used 8 second exposures, albeit a buttload of them (where 1 buttload = 4,275 subframes).

Henry Curry built the Grade II-listed Pump Room for the 7th Duke of Devonshire in 1894 due to overcrowding at the previous well in the Natural Baths. It was last used to “take the waters” in the 1970s.
The Pump Room now houses the Buxton visitor centre.

This stack of 18 images contains nearly the entirety of the constellations Andromeda, Cassiopeia, and Perseus. Numerous outstanding objects are within its bounds. From left to right (roughly east to west), they include:
The Pleiades (M45, lower left corner)
The California Nebula (NGC 1499, above the Pleiades)
The Double Cluster in Perseus (NGC 869 and NGC 884, near top center)
The Heart and Soul Nebulae (IC 1805 and IC 1848, above the Double Cluster)
M34 (open star cluster, bottom center)
The Triangulum Galaxy (M33, along the bottom border, right of M34)
The Andromeda Galaxy (M31 and satellite galaxy M110, bright elongated object in lower right area of image)
Subframes were taken with an astrophotography modified Nikon D5100 at ISO 4000 and focal length of 18mm. Stacking and processing in PixInsight, with a few final touches in Photoshop.
The solution for the image from astrometry.net places the center at
