This photograph is of Comet Neowise which passes earth once in 6,800 years.
Also this photograph is a stack of 100 photographs.
I used Deepsky Stacker to stack the images which took many hours, then the result was Post Processed in Lightroom and Photoshop to be able to bring out as much details as I could which again took many more hours.
Gear used was Canon 5D Mark IV with Canon 100-400mm F/4.5 - 5.6L IS II USM Lens on a standard tripod.

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.

Normally you can't see the Milky Way this clearly from a backyard in the city. But I took 20 exposures of 20 seconds each and combined them with 6 dark frames in DeepSkyStacker and then converted the resulting 32-bit TIFF into an 8-bit JPEG using Photoshop's HDR function.
This section of the Milky Way is at the zenith, or directly overhead from 44° N.

The Andromeda Galaxy (Messier 31) with one of its satellite galaxies, Messier 110, visible above it, and another, Messier 32 in front. This is made with ten 2-minute exposures stacked with DeepSkyStacker. That's 20 minutes of light gathering. I'm sold on the AstroTrac. Heck, I even bought one. :)
The completely black areas in the image mean I need to clean my sensor.

And what beauty the heavens hold. We have eyes that gather photons of light so that our brains may interpret the universe. These photons come at us directly, or reflect off objects and by doing so may lose some momentum, its frequency divided, modulated. Then our brain tells us what meaning, what shape and colour to assign these packets of energy.
Before telescopes were in widespread use, the Andromeda Galaxy was perceived as a curious smudge in the sky. We now understand that it is the closest spiral galaxy to us and the largest in our Local Group. The light from its stars takes 2.5 million years to reach us. On a moonless night you can see its centre as a faint smudge, but its full angular dimension is larger than the moon.

- 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.

Three is a crowd, some people say. In this image taken on the evening of April 10, 2024, even fiveastronomical objects gathered in the same field of view.
Most prominent would certainly be the crescent moon, with a clearly visible earthshine (i.e., sunlight reflected from earth to the moon, and back to earth again). Just bottom left of it, there is bright planet Jupiter showing diffraction spikes originating from the aperture blades of the lens. It is even accompanied by the Galilean moons, of which 3 can be recognized if you zoom in. Io, the innermost moon, is not visible here because it stood to close to Jupiter. Roughly at 10 o'clock from Jupiter stands the planet Uranus, which appears like a moderately bright star here, and is also dimmed a bit by the light clouds. At the left edge of the image shines the Pleiades open cluster, M45. And at about 4 o'clock from the moon, just above the tree line, you can even spot the periodic comet 12P/Pons-Brooks, which disappeared shortly after from northern skies and will reappear in 71 years from now.
This image really was quite the lucky shot. I had marked it down in my calendar weeks before, but on the big day, the weather was... not so nice. Even at sunset, it was quite cloudy, and I had almost given up hope to be able to take the shot. But around 9 pm, just before the comet was about to disappear behind the trees, it suddenly cleared up, and I hurriedly set up the tracking mount and camera. I was able to find a spot near my front door where I could peer between trees and buildings and take a number of 30 s exposures for stacking. This is the result! The image is actually a composite of one stack alinged on the stars, one stack aligned on the moon using the same raw images, and one stack without tracking or alignment for the foreground. I didn't have enough time to find and fix a ball head for leveling the image though, so this is equatorially aligned. Still looks nice though, I think.
Special thanks to my wife who made me take a look outside once more instead of just giving up!
