This is some test data from the new system 5 scope at Grand Mesa Observatory, Colorado.
Messier 61 is a barred spiral galaxy. It has undergone some gravitational disturbance probably from encounters with nearby galaxies. As a result, there is significant star formation in the galaxy with some of the more massive stars burning through their hydrogen fuel quite quickly and ending their existence as Type 2 core collapse supernovae. Several have been observed in recent years - more than usual for this type of galaxy.
Can just make out dust lanes in the barred segment.
I've processed the master subs in RGB with each comprising just 4 x RGB exposures of 300s.

Having not had a lot of telescope time during the summer months, I find myself reprocessing data collected in the past. This is a reprocessing of the Andromeda Galaxy region including insets of the two brightest satellite galaxies, M110 and M32. This is from data collected from 2015-2016. The wide-field view was collected using a Canon 6D and 400mm lens, the inset images were captured with my Meade 12” LX90 telescope.

My take on the Triangulum Galaxy (Messier 33 or NGC 598). This has been a real labor of love. After a couple editing attempts in 2020 I never achieved a result I was happy with. Revisiting the project in 2021, with more data and post-processing knowledge, I’m finally happy to share my results.
The Triangulum Galaxy is a spiral galaxy located 2.73 million light-years from Earth in the Triangulum constellation, and is the third-largest member of the Local Group of galaxies behind Andromeda and our own Milky Way. The Triangulum Galaxy is some 60,000 light years in diameter. With very little sky pollution and good vision, the Triangulum Galaxy is visible to the naked eye. With binoculars and decently dark skies much more detail, including some dust lanes, begins to resolve.
Editing Details
Color data was captured with the 2600MC and Esprit 120ED (2020) and Esprit 80ED (2021). Luminance data was captured with the 2600MM, Astronomik UV/IR L2, and my new Takahashi FSQ-106EDX4. Hydrogen-alpha comes from combining monochrome data captured with the 2600MM, Esprit 120ED, and Astronomik Hα 12nm filter (2021), with red channel data captured with the 2600MC, Esprit 120ED, and Radian Triad Ultra filter (2020). Post-processing was handled in PixInsight and Adobe Photoshop. Color data was combined, cleaned up, and calibrated, and Hydrogen-alpha data was applied to accent nebulous regions. Monochrome data was processed separately (cleaned up, deconvolution, some mild star deemphasis, adjustments to bring out structure, etcetera). After combining luminance and color data stars were separated, some additional adjustments were made, and the results were sent to Photoshop for final post-processing. In Photoshop I employed J-P Metsavainio’s tone-mapping routine; processed small fuzzies background IFN (and maybe a galactic stellar stream?) separately; employed additional measures to accent detail in the galaxy and fainter signal; then recombining stars.

This spectacular image from the Hubble Space Telescope captures the spiral galaxy NGC 105, which lies roughly 215 million light-years away in the constellation Pisces.
While it looks like NGC 105 is plunging edge-on into a neighboring galaxy, this is just a circumstance of perspective. NGC 105’s elongated neighbor is actually far more distant. Such visual associations are the result of our Earthly perspective and they occur frequently in astronomy.
Hubble’s Wide Field Camera 3 observations in this image are from a vast collection of Hubble measurements examining nearby galaxies that contain two fascinating astronomical phenomena – Cepheid variable stars and cataclysmic supernova explosions. While these two phenomena may appear unrelated – one is a peculiar class of pulsating stars and the other is the explosion caused by the catastrophic death of a massive star – astronomers use both to measure the vast distances to astronomical objects.
Both Cepheids and supernovae have very predictable luminosities. Astronomers use these so-called “standard candles” to determine distances by comparing how bright these objects appear from Earth to their actual brightness. NGC 105 contains both supernovae and Cepheid variables, giving astronomers the opportunity to calibrate the two distance measurement techniques against one another.

Here is a view of the most distant globular cluster in the Milky Way, NGC 2419, some have postulated that this may be an extra-galactic object. I have seen distances listed as high as 285,000 light-years away from Earth. It appears small and dim, but it is actually very large and very bright (if it was a bit closer to us), there are estimates of 300-400 million solar masses in this cluster.
You can also make out the galaxy NGC 2424, a barred spiral galaxy with a magnitude of 12.6. The view is dominated by the red giant star HD61294 in the lower right, magnitude 5.75, and 41 times larger than our Sun.

This wield field shows two bright galaxies. They are separated on the sky by about 0.5 degrees. Both are estimated to be around 90 million light-years away.
NGC 5078 is a spiral galaxy in the Hydra constellation, approximately 94 million light-years away from Earth. It has a diameter of 127,000 light-years and is probably a member of the NGC 5061 group. The dust lane of NGC 5078 is warped, probably by interaction with the nearby galaxy IC 879, which is itself distorted into an 'S' shape by the interaction. At the presumed distance the two galaxies would have a minimal separation of about 61,000 light-years. For comparison, the Large Magellanic Cloud is about 160,000 light-years from the Milky Way.
NGC 5101 is a lenticular galaxy in the constellation Hydra. It is separated in the sky from the spiral galaxy NGC 5078 by about 0.5 degrees, and both are believed to be at the same distance from the Earth. This would mean they are approximately 800,000 light-years apart. Both galaxies are believed to be about the size of the Milky Way.

"M101 is a large galaxy, with a diameter of 170,000 light-years. By comparison, the Milky Way has a diameter of 258,000 light years. It has around a trillion stars, twice the number in the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small central bulge of about 3 billion solar masses.
M101 is asymmetrical due to the tidal forces from interactions with its companion galaxies. These gravitational interactions compress interstellar hydrogen gas, which then triggers strong star formation activity in M101's spiral arms that can be detected in ultraviolet images. "

NGC 7331 is the prominent spiral galaxy to the right in this image. The galaxy is a bit under 50 million light years away, and it shows a complex structure of dust lanes, along with some H II regions in its spiral arms and disks. These appear as pink dots within the galaxy in this image. The left half of the image is the Deer Lick Group of galaxies. This is not a true group of galaxies -- they are too far apart from each other to be gravitationally bound in a group. They just happen to all lie in the same direction on the sky.
These galaxies pass directly overhead from my location.

Messier 63, also known as the Sunflower Galaxy, is estimated to be 27 million light-years from Earth. It is found in the constellation Canes Venatici. With an estimated diameter of 100,000 light-years, it is roughly the size of the Milky Way Galaxy.
This galaxy is a flocculent spiral galaxy. Unlike grand-design spiral galaxies, flocculent spiral galaxies do not have well defined spiral arms. Instead, they appear to have many discontinuous arms.
Messier 63 is one of the members of the M51 Group of galaxies that also includes the Whirlpool Galaxy (M51) and NGC 5195 (M51B).

My first attempt at the Triangulum Galaxy, a spiral galaxy located 2.73 million light-years from Earth in the constellation Triangulum. It is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye but only in very low light polluted areas. This is right at the limit of what my scope can presently achieve so the detail is lacking. That said I had limited data here having lost half the night's effort due to a tree invading the shots.

NGC 7331 è una grande galassia a spirale nella costellazione di Pegaso: grande sia per dimensione apparente (10,5' x 3,7' - la luna piena ad occhio nudo ha un diametro di 30') sia per dimensione reale (140000 anni luce, quindi più grande della nostra Via Lattea).
Dista da noi 45 milioni di anni luce.
Grazie anche alla sua magnitudine di 10.4, mostra parecchi dettagli sia sui bracci sia verso il nucleo.
Vicino a NGC 7331, nella parte inferiore dell'immagine, si nota un gruppo di altre galassie abbastanza luminose: si potrebbe pensare che siano fisicamente legate a NGC 7331, ma in realtà si trovano ad una distanza circa 6 volte maggiore e quindi appaiono vicine alla grande galassia solo per un puro effetto di prospettiva.
----------
NGC 7331 is a large spiral galaxy in the constellation of Pegasus: large both in apparent size (10.5' x 3.7' - the full moon with the naked eye has a diameter of 30') and in real size (140,000 light years , therefore larger than our Milky Way).
Its distance is 45 milion light years.
Thanks also to its magnitude of 10.4, it shows a lot of details both on the arms and towards the nucleus.
Near NGC 7331, in the lower part of the image, you can see a group of other quite bright galaxies: you might think that they are physically linked to NGC 7331, but in reality they are at a distance about 6 times greater and therefore appear close to the large galaxy just for a pure perspective effect.

Sweeping spiral arms extend from NGC 4536, littered with bright blue clusters of star formation and red clumps of hydrogen gas shining among dark lanes of dust. The galaxy’s shape may seem a little unusual, and that’s because it’s what’s known as an “intermediate galaxy”: not quite a barred spiral, but not exactly an unbarred spiral, either - a hybrid of the two.
NGC 4536 is also a starburst galaxy, in which star formation is happening at a tremendous rate that uses up the gas in the galaxy relatively quickly, by galactic standards. Starburst galaxies can happen due to gravitational interactions with other galaxies or - as seems to be the case for NGC 4536 - when gas is packed into a small region. The bar-like structure of NGC 4536 may be driving gas inwards toward the nucleus, giving rise to a crescendo of star formation in a ring around the nucleus. Starburst galaxies birth lots of hot blue stars that burn fast and die quickly in explosions that unleash intense ultraviolet light (visible in blue), turning their surroundings into glowing clouds of ionized hydrogen, called HII regions (visible in red).
NGC 4536 is approximately 50 million light-years away in the constellation Virgo. It was discovered in 1784 by astronomer William Herschel. Hubble took this image of NGC 4536 as part of a project to study galactic environments to understand connections between young stars and cold gas, particularly star clusters and molecular clouds, throughout the local universe.

"Messier 106 is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. M106 contains an active nucleus classified as a Type 2 Seyfert, and the presence of a central supermassive black hole has been demonstrated from radio-wavelength observations of the rotation of a disk of molecular gas orbiting within the inner light-year around the black hole."

M33, a beautiful spiral galaxy in the constellation Triangulum. It's "only" about 2.8 million light-years away, making it the next nearest large spiral galaxy to us (just beyond M31, the Andromeda Galaxy), and part of the association of galaxies called the Local Group. Had a couple of nice clear, calm nights recently, though the moon is waxing past last quarter, and local lights add to the sky brightness.

The galaxy is located 43 million light-years away in the constellation Crater (The Cup). From Hubble’s vantage point in orbit around Earth, NGC 3511 is tilted by about 70 degrees, intermediate between face-on galaxies that display picture-perfect spiral arms and edge-on galaxies that reveal only their dense, flattened discs.
Astronomers are studying NGC 3511 as part of a survey of the star formation cycle in nearby galaxies. For this observing programme, Hubble will record the appearance of 55 local galaxies using five filters that allow in different wavelengths, or colours, of light.
One of these filters allows only a specific wavelength of red light to pass through. Giant clouds of hydrogen gas glow in this red colour when energised by ultraviolet light from hot young stars. As this image shows, NGC 3511 contains many of these bright red gas clouds, some of which are curled around clusters of brilliant blue stars. Hubble will help astronomers catalogue and measure the ages of these stars, which are typically less than a few million years old and several times more massive than the Sun.
[Image Description: A spiral galaxy in space. It is seen tilted at an angle, as a stormy disc filled with clouds of stars and dust. It is coloured more yellowish in the centre, and bluer out to the edge of the disc, where the ends of curved spiral arms break away from the disc. Spots of red light scattered through the galaxy mark where stars are actively forming. The galaxy is on a black background.]

Messier 63 or M63, also known as the Sunflower Galaxy, is a spiral galaxy in the northern constellation of Canes Venatici. it contains more than 400 billion stars and lies 37million light-years from earth.
Although M63 is the central galaxy in this image, it isn't the only one. This image contains many smaller more distant galaxies as well. Every elongated or fuzzy star is actual a galaxy! I count 18, how many do you see?

NGC 891 is a reasonably bright and fairly large spiral galaxy in the constellation Andromeda that was missed when the French astronomer Charles Messier compiled his well-known list of deep space objects in the late-1700s.
This galaxy is believed to be very similar in size and structure to our own Milky Way and is about 30 million light years from earth. Interestingly, while earth-based astronomers have a fine view of NGC 891 it would be very difficult to look back from this galaxy and see the Milky Way since the view of our galaxy would be blocked by the dust lanes that so prominently bisect NGC 891.
There are numerous background galaxies in this image, the most obvious being the small, 13th magnitude spiral NGC 898 that is visible on the lower right (distance approximately 250 million light years). You should be able to easily identify nearly a dozen others and there are many more that appear as small, fuzzy stars.
The imaging sessions to create this picture were done over two nights in September 2015 using a 5-inch aperture, f/5.2 telescope and an unmodified Sony NEX-5R digital camera (60 seconds x 137, ISO 800, producing a total exposure integration time of two hours and seventeen minutes).
This image is best seen at full size (1920 x 1000) or in the Flickr light box (press the “L” key to enter the light box and/or click on the image to see it at a larger size).
Image processing done with PixInsight v1.8, Photoshop CC 2015, and Mac OS X’s Preview application.

Taken at 9000 feet up near Cameron Pass, Colorado. I've had my telescope out many times now and in many different locations around the state. This was the first that had no apparent light pollution. Just lovely, clear, dark skies.
Here are the gory details: Canon 20D at ISO 800 with a 100-400mm lens set to 300mm and f/7.1 (or so). I stacked 11 shots with varying exposure times: 1 at 30 seconds and 2 each at 1, 2, 4, 8, and about 20 minutes for a total of about 70 minutes of exposure. I used noise reduction for all shots so each had its own dark frame subtraction. I manually guided all shots through the 9.25 inch scope on the Orion Atlas mount.

NGC 2903 is found atop the brow of Leo at a distance of 30 million light years. The classic barred spiral hosts vigorous star formation concentrated toward the center.
This image was captured under high desert skies near Santa Fe, New Mexico, USA with a telescope of 12" aperture at f/8 and an electrically-cooled CCD camera. Total exposure was 6 hours (Ha-LRGB).
In my view of the Draco Trio you see a close grouping of three very different looking galaxies. There is a spiral galaxy on the top, NGC 5985, the elliptical galaxy NGC 5982, and on the bottom is the edge-on spiral galaxy designated as NGC 5981. All are part of a large group of galaxies called the NGC 5982 cluster. This image is about four hours of collected data.

The first opportunity to do some imaging in a long time. We opted for a fairly simple target and one we haven't imaged for 6 years. With a very clear night and everything working properly, we were able to get a lot of exposure on this object which resulted in a much better image and easier processing.
NGC 2403 (also known as Caldwell 7) is an intermediate spiral galaxy in the constellation Camelopardalis. It is approximately 8 million light-years distant and 90,000 light-years in diameter. It bears a similarity to M33, containing numerous star-forming H II regions.

This 2009 image of the spiral galaxy Messier 101 (M101) is a composite of data from NASA's Chandra X-ray Observatory, the Hubble Space Telescope, and the Spitzer Space Telescope. The colors correspond to the following wavelengths: The X-rays detected by Chandra are colored blue. Sources of X-rays include million-degree gas, the debris from exploded stars, and material zooming around black holes and neutron stars. The red color shows Spitzer's view in infrared light. It highlights the heat emitted by dust lanes in the galaxy where stars can form. Finally, the yellow coloring is visible light data from Hubble. Most of this light comes from stars, and they trace the same spiral structure as the dust lanes.
M101 is a face-on spiral galaxy about 22 million light years away in the constellation Ursa Major. It is similar to the Milky Way galaxy in many ways, but is larger. The new "Great Observatories" composite image of M101 was distributed to over 100 planetariums, museums, nature centers, and schools across the country in conjunction with Galileo's birthday on February 15. The year 2009 marks the 400th anniversary of Galileo's telescope and has been designated the International Year of Astronomy to celebrate this historic anniversary.

Eine Spiralgalaxie.
Mein erstes Foto aus Insta, endlich. Bloß: Jetzt geht die Kommentierfunktion nicht mehr, Mist.
A beautiful but skewed spiral galaxy dazzles in today’s NASA/ESA Hubble Space Telescope Picture of the Week. This galaxy, called Arp 184 or NGC 1961, sits about 190 million light-years away from Earth in the constellation Camelopardalis (The Giraffe).
The name Arp 184 comes from the Atlas of Peculiar Galaxies, which was compiled by astronomer Halton Arp in 1966. The 338 galaxies in the atlas are oddly shaped, tending to be neither entirely elliptical nor entirely spiral-shaped. Many of the galaxies are in the process of interacting with other galaxies, while others are dwarf galaxies without well-defined structures. Arp 184 earned its spot in the catalogue thanks to its single broad, star-speckled spiral arm that appears to stretch toward us. The galaxy’s far side sports a few wisps of gas and stars but lacks a similarly impressive spiral arm.
This Hubble image combines data from three Snapshot observing programmes, which are composed of short observations that can be slotted into time gaps between other proposals. One of the three programmes targeted Arp 184 for its peculiar appearance. This programme surveyed galaxies listed in the Atlas of Peculiar Galaxies as well as A Catalogue of Southern Peculiar Galaxies and Associations, a similar catalogue compiled by Halton Arp and Barry Madore.
The remaining two programmes were designed to check up on the aftermath of fleeting astronomical events like supernovae and tidal disruption events — when a star is ripped apart after wandering too close to a supermassive black hole. Since Arp 184 has hosted four known supernovae in the past three decades, it’s a rich target for a supernova hunt.
[Image Description: A spiral galaxy seen at a skewed angle. Its centre is a bright spot radiating light. A thick, stormy disc of material surrounds this, with swirling strands of dark dust and bright spots of star formation strewn through the disc.
