Here are a few new images I have finished recently.

The first one is M8 (the Lagoon Nebula). This is one of the most photographed regions of the sky and has been done by almost all astrophotographers, so, I needed to make it special somehow -- not an easy feat.

This was done in Chile at SWOS (Stellar Winds Observatory South) using a 24” PlaneWave CDK. The filter set was 7 filters LRGB,HA,S2,03. I first removed all the stars in the narrowband images and combined them in Photoshop and then added the RGB stars in selectively. I tried to get as much different color definition as I could to show all areas of this great nebula.

The second is the Grus Trio (NGC 7582,7590 and 7599). There are few images of this Trio to date. This was also done with the same telescope with a filter set of LRGB. This is a beautiful trio of galaxies that really looks wonderful together.

"Time"

Three years of tries, the first 360 degree startrail of my life. It gets the title of my favorite song, the Hans Zimmer track named Time, the meanings are multiple: from the time it took to figure out how to do it, to the exposure time of this shot, an entire night while our planet rotated on itself and the stars "made their circles" around the two poles.
I finally found a good compromise. Once I understood the settings (even there I fought a lot trying the right settings during the shooting) I began to study how to assemble everything, this time I used a few shots, the first (yes, it will be the first of a loooooong series) I wanted it very delicate, as I imagined in my head from that day, exactly so

The dumbell nebula by William Ostling, on Flickr

When Hubble processes images, they usually crop to the most interesting part. This image, however, shows the entire area captured by the sensor! The pure black areas in this image are parts where there is no sensor.

This image looks to me more like a painting than a photo. Tho colors, the bulbous shapes, the small details all look like oil on canvas.

Taken over the course of this summer, this is my first submission for an APOD! Hubble's famous "Pillars of Creation" photo is the very thing that made me get outside and look up in the first place. Years later it still takes my breath away with every sub-frame. Thank you for considering my submission.

I’ve been doing this for a little over a year and find it so fascinating that you can take pictures of space with just a camera and a telescope. This picture of the beautiful star forming region Melotte 15 in the center of the Heart Nebula (IC 1805) was taken on the night between 30-31 of august 2021 from my aunts balcony in a suburb to Stockholm, Sweden and just about four hours of integration with my ASI 1600mm pro, 150/750 Newton telescope and 7nm bandpass for Hydrogen, Sulfur and Oxygen. Processed in Pixinsight and mostly just color balanced and noice reduced. Still learning this amazing hobby and planning on doing this for a long time!

NGC 3603 by William Ostling, on Flickr

A full write up is here to read (with processing steps): https://theastroenthusiast.com/ngc-3603-from-hubble/

Like a 4th of July fireworks display, a young, glittering collection of stars looks like an aerial burst. The cluster is surrounded by clouds of interstellar gas and dust—the raw material for new star formation. The nebula, located 20,000 light-years away in the constellation Carina, contains a central cluster of huge, hot stars, called NGC 3603.

This environment is not as peaceful as it looks. Ultraviolet radiation and violent stellar winds have blown out an enormous cavity in the gas and dust enveloping the cluster, providing an unobstructed view of the cluster.

This tree is asking us some aid, compassion.
It seems that is showing Sky the way to problem, just look down here, looking for some divine help.
For this reason I decide to name this work "Earth's Calling".
Like every year in this period, we went to Pollino National Park to spend the night and make some stunning nightscape.
This time the conditions was perfect, showing us a beautiful and clean sky, maybe as never I look before.
After 8km hike I was gone, but the saw of this amazing opportunity make me alive again and ready to shoot all night long..or so.

I would like to share with you a very special project, my deepest image to the date.

This image, with a total integration time of more than 170 hours, is the result of the work I’ve been doing during the last 4 years. All this time I’ve been capturing several images of the Cygnus constellation at different focal lengths and resolutions in order to obtain a high resolution wide field image of this amazing Milky Way region. I combined regular camera lenses and an APO telescope, both paired with dedicated astrophotography cameras.

Full details on my webpage: https://astrocat.info/cygnus-the-wide-field-magic-line/

New version of my detection of light echoes from SN1987a:
Deep View of the Tarantula Region with Light Echoes from SN1987a - Narrowband Bicolour

Link to full resolution image
Link to animation of the propagating light echoes


This image shows what I believe is the first amateur detection of light echoes from SN1987a - 33 years after the event. The light echoes are produced when the initial flash from SN1987a is subsequently reflected off interstellar dust as light travels outward from the event. Direct light from the supernova was observed on Earth in 1987, and we then see light reflected from dust in the interstellar space arriving later because it has travelled further to reach us.
The detection of light echoes was created by subtracting two Luminance images taken almost 8 years apart, on 24th Oct 2012 and 21st Sep 2020 respectively, in order to create a difference image which was then superimposed on a regular colour image of the area. The expanding light echoes appear as roughly circular concentric arcs, centered on SN1987a's location.

The image is a mosaic of two deep fields centered near the bright Tarantula Nebula (NGC 2070) in the Large Magellanic Cloud (LMC). The field is filled with numerous bright colourful nebulae and star clusters (an annotated version is available here). At the LMCs distance of approximately 160,000 light years, the field of view seen here spans a massive 2850 x 1950 light years! At this large scale the nebulosity seem to feature many bubble shaped voids of different sizes. These are formed by the radiation pressure from young star forming regions and shockwaves from ancient supernovae. The small but comparatively recent supernova remnant of SN1987a is also visible here, as a tiny pink dot in the upper part of the image - if you know where to look.

The Tarantula Nebula
The Tarantula Nebula, named for its appearance that somewhat resembles a giant spider in the sky, is the largest known emission nebula in the Local Group of galaxies. The nebula is about 1000 light years wide and would appear bright enough to cast shadows if it was as close to us as the Orion Nebula. It is, however, located 160,000 light years away in the Large Magellanic Cloud, the largest of the dwarf galaxies that accompany our Milky Way.
In the very centre of the nebula lies R136, a super star cluster which is a very large region of star formation thought to be the precursor of a globular cluster. It is a very young cluster at only 1-2 million years and consists of giant and supergiant stars of which the majority are spectral type O3. The cluster also contains several Wolf-Rayet stars.
Speculation long surrounded the nature of the central component of the cluster, named separately as R136a, and it was once thought to be a single hypergiant star of an incredible 1500 solar masses. R136a's true nature was recently resolved by holographic speckle interferometry and found to be a dense star cluster containing very massive and luminous stars. Three extremely luminous stars (R136a1, R136a2 and R136a3) dominate this cluster and are separated by only 0.10 and 0.48 arc seconds. R136a1 is the most massive star found to date with 265 solar masses, as well as being the most luminous at 10 million times the brightness of the Sun.
The entire R136 super cluster produces most of the energy that makes the Tarantula Nebula visible. The estimated mass of the cluster is 450,000 solar masses, suggesting it will probably become a globular cluster in the future.
A super star cluster, named Westerlund 1, also exists in the Milky Way but is heavily obscured by galactic dust.

Hi everyone

This is my first submission ever...
ImageNGC6188_6164 by Steeve Body

See the full res here: https://www.astrobin.com/full/3dbeng/0/

I guess what is interesting about this picture is that it was taken using an entry level mirrorless DSLR than I picked up on eBay for $200 and removed the IR/UV filter...

This is my version of NGC 6188 and 6164 Mosaic project…
140 x 360s shots later, 14h of data total. 91 million pixels captured across 11 panels.. but I still ended up cropping the image vertically as I did not like the landscape look for this target…
This was SO much work, but well worth it I think.. This marks my first year anniversary of me taking up this hobby.
I not too sure I can get much more out of this camera. My sensor was hitting 37 degrees the other night when ambient temperature was about 17 degrees… and processing took a while to get right and eliminate noise without destroying details. Summer is not going to help… I can’t wait to get my hand on a cooled camera so I can take my images to the next levels.
I hope you like it 🙂

Crescent Moon over Venice
instagram.com/stefano.derosa_photography
Copyright: Stefano De Rosa Please find above two images taken before sunrise on September 4, 2021, from two iconic locations of Venice (Italy) that is currently hosting the “Venice International Film Festival”.
Also in the sky there was a great show: the “main star” was a Crescent Moon with a beautiful earthshine.
In the first picture, taken from the bridge “Ponte dell’Accademia”, our natural satellite is shining over the Grand Canal; the church at the center of the frame is “Saint Mary of Health”.
In the second image the Moon is “close” to the St Mark's Campanile over an extraordinarily empty San Marco Square.

Hi! A supernova remmant, 57 h exp time in HOO palette. It's size in the sky is similar to the size of a full moon. It's outer shell has ruptured between the 10 and 11 o'clock position. Originally this was thought to be a Planetary nebula (Abell 85) but in 1971 it was determined that is actually a supernova remmant.

NGC 7640 in Andromeda. KG Observatory, Julian, CA.

Discovered on October 17, 1786 by the English astronomer William Herschel, NGC 7640 is an 11th magnitude barred spiral galaxy.

Also known as LEDA 71220, UGC 12554 and IRAS 23197+4034, this galaxy is located in the constellation Andromeda, 38.8 million light-years from Earth.

Galaxies of this type are recognizable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s center.

NGC 7640 might not look much like a spiral in this image, but this is due to the orientation of the galaxy with respect to an observer on Earth.

There is evidence that this galaxy has experienced some kind of interaction in its past.

This picture is the result of a photo experiment where I wanted to capture the "inverse" Milky Way arc facing towards Northern direction (from the Northern Hemisphere).
I have seen thousands of wonderful nightscape photos where the main subject is the complete Milky Way arc above wonderful foregrounds. But almost all of them depicts the Southern horizon. It's obvious as the center of our Galaxy is visible on the Southern sky.
But here I wanted to record the Arc with the Big Dipper and the Polaris. As you can see it's very hard to recognize the constellations due to the HEAVY perspective distortion and the Milky Way has a strange "inside out" view.

The location of the photo is the annual astro camp of Hungarian Astronomical Association in Gerecse Mountain near Tarján (~50km southwest from Budapest). Last year the event was cancelled, this year the crowd was halved to be due to COVID-19 pandemic, but at last I was able to met some old friends of mine.
