Continuing my quest for difficult and rarely imaged distant objects, I came across this image of NGC 5216/5218 by Adam Block...

https://www.adamblockphotos.com/ngc-5216.html

This is LRBG = 10:4:4:4 hours in his 32-inch Schulman RCOS.

Unfortunately the wind and sky this month didn't permit 20+ hours in the Planewave 24". But fortunately I had one long night with exceptional seeing, down to 1.5" FWHM measured on 15-minute subs. (-:

I'm pleased with the overall results and the additional galaxy (NGC5205 @ 103.5 MLY!) that happpened to be in frame.

From Adam's APOD...

"Galaxies NGC 5216 (left) and NGC 5218 really do look like they are connected by a string. Of course, that string is a cosmic trail of gas, dust, and stars about 22,000 light-years long. Also known as Keenan's system (for its discoverer) and Arp 104, the interacting galaxy pair is some 17 million light-years away in the constellation Ursa Major. The debris trail that joins them, along with NGC 5218's comma-shaped extension and the distorted arms of NGC 5216, are a consequence of mutual gravitational tides. The tides disrupt the galaxies as they repeatedly swing close to one another. Drawn out over billions of years, the encounters will likely result in their merger into a single galaxy of stars. Such spectacular galactic mergers are now understood to be a normal part of the evolution of galaxies, including our own Milky Way."

The rose of space: I present the rosette nebula

The petals of this cosmic rose are actually a nursery of stars.
What characterizes this image is the sculpture drawn by the globules of dark dust.
The stars emit ultraviolet radiation that ionizes the surrounding hydrogen cloud, which gives the image a red color.

Dobogó-kő Startrails
Copyright: György Soponyai

Dobogó-kő is the highest peak of the Visegrád Mountains (700 meter) in Hungary. The peak has a wonderful outlook towards Northern direction with the Danube Bend as it flows between Börzsöny and Visegrád Mountains. Hungary has a terrible astro climate: the country (and mainly the amateur astronomers living here) "suffer" every Fall and Winter from dense fog that stales for weeks blocking all lights from the skies.

27th January 2020 was yet another foggy day so I decided to travel to Dobogókő (the nearby village -- without hyphen) that was above of the cloud layer according to online webcams. I initially planned to capture the setting crescent Moon but by seeing the wonderful, crystal-clear skies I quickly changed my mind and created this "Standing at the Seaside of Clouds"-style startrail photo.

Comet C/2017 T2

Comet C/2017 T2 (Top-Left) approaching close to the double star cluster on January 27th, 00:47ut. The Double Cluster, or Caldwell 14, is the name for two open clusters – NGC 869 and NGC 884 – located close together in Perseus constellation.

M78 (NGC 2068) is a diffuse reflection nebula, 1600 light years away and located in the constellation of Orion.
Together with her we can also see the nebulae NGC 2064, NGC 2067, NGC 2071 and various HH objects, the latter are formed when the ionized gas expelled by the young stars collides with denser gas and dust, causing the phenomenon of triboluminescence. (source Wikipedia)

Great picture, Brent! I love the way the bluish halo envelops Andromeda like a mist.

First opportunity to image since November. The Julian winter skies prevented imaging in December. So more holiday time with the family. (-:

I wanted to start the new decade with something very difficult, very far and rarely imaged. NGC2655 at 80 Million Light Years - FAR beyond the bright stars of our own Milky Way galaxy (shown here) - was my choice.

"Floating in the serenity of the universe like a cosmic ammonite shell, NGC 2655 is an impressive example of a lenticular galaxy. Located 80 million light years away towards the constellation of Camelopardalis (The Giraffe), its series of outer shell structures and faint tidal loops are nicely complemented by internal dust lanes near its core.

Its panoply of morphological kinematics are indicative of a merger between two galaxies in the past, an intergalactic event that is now known to be a common feature of the evolution of galaxies. Other signatures of a past merger that aren't apparent to the eye are vast clouds of neutral hydrogen surrounding the galaxy that were uncovered in observations made using radio telescopes.

The unusual appearance of NGC 2655 brought it to the attention of the famous astronomer Halton Arp who added it to his atlas of peculiar galaxies under Arp 225. Another distinction is that the core is very luminous, which means that NGC 2655 belongs to the category of active galaxies known as Seyfert galaxies, which were named after the astronomer Karl Seyfert. The luminosity of Seyfert galaxies is thought to derive from a transfer of matter onto an accretion disk around a supermassive black hole.

The diameter of NGC 2655 is approximately 200,000 light years but the envelope of neutral hydrogen gas discovered in the 1980's is about 500,000 light years."

Wow, that's a fantastic image! And I had most certainly never seen this galaxy before! :D (Hope you don't mind that I inserted a version of your picture from your website, as the attachment wouldn't have shown up when I quoted your post.)

Shell galaxy NGC 474 and small ring galaxy NGC 470. Photo: Mischa Schirmer
You quoted a text that described NGC 2655 as a galaxy with a "series of outer shell structures". I disagree. Take a look at the picture of NGC 474, which is a true shell galaxy, and note how it differs from NGC 2655. The shells of NGC 474 are extremely circular and sharp, and the obvious tidal features are also elegantly symmetrical.

I think that NGC 2655 is a fantastic spiral galaxy. Its spiral arms are broad and diffuse, because NGC 2655 no longer forms any stars, but the arms are still clearly discernible, and they are very long. One outer arm appears to make almost two full turns around its parent galaxy!

The arms are asymmetrical, like practically all galactic spiral arms are. That's all the more proof that they are spiral arms and not shells.

It's a superb image! Thanks!

Ann

High Resolution Moon

This image records detailed lunar features over the entire visible surface of the Moon as it approaches Last Quarter. The full-sized image is 7000x10,000 pixels, with an image scale of 409m/px as measured near the apparent center of the lunar disk (sub-observer point). This is sufficient for the resolution of small craters to about 1km diameter across the image. The image is a mosaic composed of four panels taken with a C9.25 Edge HD telescope and ASI183mm camera using a green filter (bandpass 500-575nm), combined with color data taken with a Nikon D5600 and a 6" Newtonian telescope. The monochrome image panels are each composed of stacked images, corresponding to 1000 stacked frames (out of 5000 total per panel). The image was acquired on September 21, 2019 at approximately 12:30UT (monochrome imaging spanned about 30 minutes, with color captured after). The full sized image is available by direct link below (might be slow to load), or by navigating through the Flickr thumbnail link.

Flight over the lunar South Pole

This image shows a detailed view of the southern limb of the Moon. The sunset terminator is at left, and is approaching the well-known craters Clavius and Tycho as the Moon nears Last Quarter. The prominent mountains on the limb at the top of the image rise over 6000m above the surrounding terrain. The image was taken with an ASI183mm monochrome camera and C9.25 Edge HD telescope, using a green filter (bandpass 500-575nm). 1000 individual frames were stacked, out of 5000 collected in total. Color was added separately with data collected at the same time with a Nikon D5600 and a 6" Newtonian telescope. The image was captured on September 21, 2019 at 12:28UT.
