Discovery of an emission nebula in direction of Tarazed

An emission nebula has been discovered in close apparent proximity to Tarazed (aka γ Aql). The diameter of the nebula is about 27.4 arcmin and its center is about 7 arcmin away from Tarazed, which is known to be an X-ray source. However, it is most likely not the ionization source of the nebula.

Rosebud Nebula
NGC 7129. Sometimes called the Rosebud because of its infrared appearance in a well-publicized Spitzer image. This is a dusty nebula and most of the light we see is reflected and scattered from the hot blue cluster of stars in its center. But it is also highlighted by some HII regions glowing in red, and if we look carefully we can see denser dust forming a dark nebula. This image represents about 17 hours of total exposure time.

Also attached here is the original Spitzer image matched to my optical one. The IR shows the warm dust as red, and can see deeper through it than is possible with visible light. Ionized hydrogen is seen as green. (It's interesting to blink between the two images.)

M33 is a perennial favorite for imaging and for good reason. This was my third attempt and on the largest scope with the finest image scale and I was amazed at the level of fine detail visible in the galaxy. It's worth viewing at full size! This is 40h 55m of HaLRGB data. You can see all the technical details as https://www.astrobin.com/tc7lfw/

NGC 1491, also known as LBN 794 or SH2-206, is a bright emission-type nebula located approximately 9,800 light-years from Earth in the constellation Perseus. The nebula obtains its dark red coloring due to Many massive stars (such as BD+50 866) embedded in NGC 1491 produce lots of ultraviolet radiation energizing/ionizing the hydrogen gas that makes up the nebula.

The Rice Hat Nebula, also known as Sh2-224, is a supernova remnant located about 14,700 light-years from Earth. It has an apparent size of 20 x 3 arc-minutes and a true diameter of 163 light-years.

This is a supernova remnant located in the Constellation of Auriga. The shape of this nebula resembles "DouLi" - a conical hat typically made with bamboo which is often seen in Asian countries. I managed to spend 26 hrs on this target with ASI294 mm Pro camera and Astronomik RGB filters. The Sii was pretty weak so early on I decided to go with the HOO palette.

The Heart Nebula in SHO by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/the-heart-nebula-in-sho/
This was a really fun dataset from telescope live to process! I’ve never seen the wider structures to the right of the heart nebula, so I spent a lot of time trying to get it to show up. I also spent a ton of time working with color masks to give the diffuse gas a red color while keeping the sho pallette!

Sprawling across almost 200 light-years, emission nebula IC 1805 is a mix of glowing interstellar gas and dark dust clouds. Derived from its Valentine’s-Day-approved shape, its nickname is the Heart Nebula. About 7,500 light-years away in the Perseus spiral arm of our galaxy, stars were born in IC 1805. In fact, near the cosmic heart’s center are the massive hot stars of a newborn star cluster also known as Melotte 15, about 1.5 million years young. A little ironically, the Heart Nebula is located in the constellation of the mythical Queen of Aethiopia (Cassiopeia). This deep view of the region around the Heart Nebula spans about two degrees on the sky or about four times the diameter of the Full Moon.

The Small Magellanic Cloud by Alessandro Carrozzi, su Flickr

The Small Magellanic Cloud
Among those who have pondered the nature of this small, fuzzy spot in the southern sky were Portuguese navigator Ferdinand Magellan and his crew during their first circumnavigation of the Earth in the early 16th century. Over the past century, it has been discovered that this 'cosmic cloud' is actually an irregular dwarf galaxy, a satellite of our Milky Way. The Small Magellanic Cloud spans about 15,000 light-years and contains several hundred million stars. It is located approximately 210,000 light-years away from us. This image also features the globular cluster 47 Tucanae to the right.

The Road to the Stars by Nathan Eaton Jr., on Flickr

After a long session capturing images of the Milky Way in Big Bend National Park for time lapse, my son Brian and I headed back to the Chisos Basin, stopping along the way at a spot I had mapped out in PhotoPills to capture a shot with a perspective view of the road ahead with the Milky Way beyond.

Initially the plan had been to capture a sequence of relatively short exposure images with separate foreground and sky shots at different ISO, then stacking registration frames to get the highest quality result possible. Unfortunately, just as I was setting up, we saw headlights down below. With such dark skies, the headlights were obvious while the car was still on Gano Springs Road and about 4 miles away so we knew we had 5-6 minutes but that wasn't enough to capture the planned sequence, just enough to get the composition framed and focused using test shots. I went for one 30 second shot knowing I'd get a little star trailing, then we threw everything back in the car and headed to the lodge. We had finished with enough time that the other car was still a mile or more behind us.

To pull out detail in the foreground, I did initial adjustments to the sky such as exposure, curves, white balance, etc. and then used the Lightroom sky masking tool to mask the sky, inverted it and then made adjustments to lighten the foreground. After touching up some noise spots with the healing brush, this is the end result.

The Milky Way rises above the Pink Clubhouse and Porter Turret Telescope of the Springfield Telescope Makers in Springfield, Vermont one evening of the annual Stellafane convention in August of 2023. The club is celebrating its centennial this year, founded on December 7th, 1923 by Russell W. Porter. This founding of the Springfield Telescope Makers kicked off a wave of amateur telescope making, the renown of which led Porter to work on the 200 inch Hale Telescope at Mount Palomar and the design of the Griffith Observatory, among many other things. To this day, the STMs continue to hone and perfect the craft of hand made optics, and celebrate astronomy through the Stellafane convention.

Without a doubt one of my favorite natural elements are volcanoes, during this time I was able to marvel at their majesty and the presence they impose on the environment.

Observing the Milky Way from above in one of them is an unforgettable experience.

We can see the Osorno volcano aligned with the Milky Way next to the galactic center, on the edges we can see the airglow, warning of a storm in the area.

I visited The Science Museum in central London last week and my primary target was the capture of Sir Isaac Newton's Astronomical Clock which is on display on the second floor and where one will find the Clockmaker's Museum. Absolutely no use of tripods is allowed and which made for lots of "fun" capturing a properly framed and exposed photo.

The second primary target for my visit to London last week and also at The Science Museum was this stunning example of an astrolabe and which is dated from 1607-1618 AD. Amateur astronomers and particularly those getting their first steps with the night sky use planispheres and which, of course, are a direct descendant of the astrolabe.

Here is panorama of the Milky Way that I did last April in Tenereife


Milky Way Arch over Teide National Park by Martin Giraud

In this picture you can see the Arch of the Milky Way above rocks of the caldera of Teide volcano. You can also see some clouds of dust brought by the calima (wind from Sahara).

I'm quite happy with the result as I tried several times to create milky way arch panorama and the edit was always a nightmare. After several unsuccessful tries, I decided to give me another chance on this one and finally succeed (to my mind) to get something I like.

For the sky 30 tiles panorama, where each tile is a stack of 3 pictures.
For the foreground I shot it during blue hour just after the night, with the same equipment.

Story:
In the heart of the Atacama Desert in Chile, a mesmerizing astrophotograph captures the celestial spectacle above. The sprawling expanse of the Milky Way arches gracefully across the sky, weaving a luminous tapestry of stars that illuminates the desert night. Framed within this cosmic canvas are the Southern Hemisphere's prominent emission nebulae, their vibrant hues contributing to the celestial ballet overhead. Among these celestial wonders, the Magellanic Clouds, ethereal galaxies visible to the naked eye, add a touch of cosmic grandeur to the scene.

The atmospheric splendor of the Atacama's night sky is further enhanced by the subtle dance of airglow, casting a surreal palette of green, yellow, and red tones. This celestial phenomenon occurs as molecules in the Earth's upper atmosphere release stored energy in the form of light, creating an otherworldly glow that complements the stellar display. Against the stark backdrop of the desert landscape, the vivid celestial tapestry and atmospheric radiance unite to create a breathtaking panorama, showcasing the unparalleled beauty of the night sky in one of the world's most astronomically privileged locations.

This astrophotograph serves as a testament to the pristine conditions of the Atacama Desert, where the absence of light pollution and the high-altitude vantage point converge to offer a front-row seat to the celestial wonders that adorn the Southern Hemisphere's night sky. Each element captured in this image tells a story of the cosmic ballet that unfolds above, inviting viewers to marvel at the profound beauty and intricate interplay of celestial phenomena in the vast and remote expanses of the Chilean desert.

Bracken House Astronomical Clock
http://www.perseus.gr
Copyright: Anthony Ayiomamitis

The Bracken House Astronomical Clock in central London is quite unique for not having any hands to display the necessary information available with such clocks. The dials rotate into the proper position so as to have the details of interest display at the 12 o'clock position. The sole exception is the day of the month and which is displayed immediately below the caricature at the center. As for the caricature, it is that of Winston Churchill and who was a personal friend of the building's owner and founder of the Financial Times newspaper.
