Sh2-170 - Little Rosette

Sh2-170 is a small and faint emission nebula located in Cassiopeia. Stock 18 is a small star cluster in the center of the nebula, which helped me find more information about this target. It seems to be located around 9,000 light-years away from Earth. The nebula resembles the Rosette Nebula, a famous winter target for us in the northern hemisphere, and therefore it's referred to as the little or small rosette nebula.

The Cygnus Loop and the Star Gienah

Image captured and processed by Matt Harbison

I call it, "The Dragon's Wing".

From Sky Safari- Epsilon Cygni is the third-brightest star in Cygnus, the Swan, at magnitude 2.46. Its traditional name is Gienah, which derives from the Arabic word for wing, "janah". However, Gamma Corvi has an identical traditional name. To differentiate them, γ Crv is referred to as Gienah Ghurab "Wing of the Raven" or Gienah Corvi; and ε Cyg as Gienah Cygni.

Variable star Wolf Rayet 134 in narrowband using HOO palette. Bubble nebula is the result of strong radiation and stellar winds from the star. It is 4 times the size of the sun with a 63.00K temperature that makes it 400.000 times brighter than our sun.

NGC6984 by William Ostling, on Flickr

All data was taken by Hubble's Advanced Camera for Surveys (ACS).


This object was a lot of fun to process! I love adding h-alpha to continuum data, and this was no exception.

Details:
Data was taken from the following proposals:
https://archive.stsci.edu/proposal_sear ... t&id=13782
Red: 814w + 665n
Green: 555w
Blue: 435w

Processing(all in pixinsight)
- crop
- color calibrate rgb
- subtract red from h alpha to just get starforming regions
- boost red and a bit of blue with h alpha
- stretch
- combine with l data
- multiscale processing

THE LONE GLOBULAR CLUSTER M30 IN THE CONSTELLATION CAPRICORNUS

M30 is a globular cluster, located in the constellation Capricornus, about 28,000 light-years from Earth.

It was discovered in 1764 by the French astronomer Charles Messier, this cluster is little photographed and difficult to locate, it is not visible to the naked eye, with an apparent magnitude of 7.2, its main reference being the 41-Cap star (located in the upper left corner of image).

The core of M30 exhibits a very dense population of stars and has suffered a core collapse, similar to some other clusters in the Milky Way.

Due to its retrograde orbit through the inner galactic halo, this cluster is believed to have been acquired from a satellite galaxy in the past.

Milky Way and Red Sprites

Copyright: Robin Onderka / www.instagram.com/robin_onderka

This photo was taken when I was setting the exposure with the model at Punta Planka, Ražanj (Croatia). However, it carries one very rare light phenomenon, the red sprites. This large electric discharge, which you can see to the left just above the horizon, occured high above thunderstorm clouds somewhere over the Adriatic Sea. And it was this millisecond flash that appeared just at the same time as the camera was capturing the center of the Milky Way and model looking at a beacon in the background.

to make this photo we are taking around 700 photos and we chose the best with meteors, the photo was taken from the cave with lime stone roof and the floor is covered by sand

A Sagittarius triplet – M8, M20, and NGC 6559 by William Ostling, on Flickr

This so far is my favorite image! Nearly 21 hours of data (taken across 4! nights) and 3 hours of processing went into this huge project. I love the color range so much - golden milky way stars, pink lagoon nebula, and light blue trifid reflection.

Some general details that I am proud of:
- taken across 4 nights (8/7/2021, 8/8/2021, 8/11/2021, 8/14/2021)
- used my old violin strings to create diffraction spikes
- I temperature matched the dark frames more accurately than I had dome before.

I hope you enjoy! Thanks for considering.

MOON IN COLOR

This image is not a mosaic

BEST DETAIL: https://www.astrobin.com/full/cg4fdc/B/


The moon is usually seen in subtle shades of gray or yellow.
The different colors are recognized to correspond to actual differences in the chemical composition of the lunar surface. Blue hues reveal areas rich in ilmenite, which contains iron, titanium and oxygen, mainly titanium, while orange and purple show relatively poor titanium and iron regions.
White areas are taller areas that are most exposed to the sun.
Trips to the moon have already been indicated by similar images.

M31, the Andromeda Galaxy 🌌

What would you image if you want to test the capabilities of your new camera?
So many options, but I settled on M31 for starters.

I’ve shot this great Galaxy already a few times with different setups so I could do a proper comparison.

And to cut a long story short; it does the job brilliantly! Although the camera lacks some megapixels compared to my dslr, the advantages of cooling and much higher sensitivity clearly outweighs the disadvantage of ‘only’ 9mp.

The Ha region clearly showed up in the longer exposure through the dual narrowband filter.

The Andromeda is part of the Local Group, together with the Triangulum Galaxy, a few dozen satellite galaxies and dwarf galaxies, our closest neighbors in the vast universe. Only 2.5 million light years away..

Two of M31’s satellites are visible in the picture, below is M32 and above the nucleus to the left is M110.

The Soul Nebula

While the rain lashed against the windows for the last few days, I took the opportunity to edit this data I shot a few weeks ago.

It such a diverse target. When really looking close you’ll find walls of gas, not unlike the famous Cygnus Wall.

The Soul Nebula (Westerhout 5) is an emission nebula located in the constellation Cassiopeia.
