Nebulae in the Swan - A gaseous beginning - Part 2.
Well, continue with the second part of this cut through all the images that I have been able to obtain of this fascinating constellation that is full of gas and dust, so without further delay we are going for it.
A constellation filled with gas and dust
In this large field image you can see the vast majority of deep sky objects that populate the constellation of the Swan, in the first part we could see this same image but in LRGB, this time we can see the same image but changing the L for Ha, which results in a greater sense of volume in the same image.
This nebula is located very close to the star Sadr and the nebula IC 1318. In the complex of NGC 6914 we find different types of nebulae: Emission nebulae that are those that glow red, We can also see dark nebulae that are clouds of black dust, and finally we can also observe Reflection nebulae, we can see this type of nebula in the form of blue lobes in the center of the image, these nebulae do not shine with their own light, but reflect the light of Nearby stars, shining with that blue hue typical of reflection nebulae, these three lobes are what have been cataloged as NGC 6914.
DWB 111- Propeller Nebula
DWB 111 also known in English as "Propellor Nebula", although its translation into Spanish may make us confuse it with the other Helix nebula found in the constellation of Aquarius, cataloged as NGC 7293, but unlike NGC 7293 which it is very low for the Northerners, DWB 111 is during the summer in the highest sky.
The objective is located between Vega and Deneb, although within the constellation of the Swan, the image that is on these lines has been obtained using narrow band filters (Ha, SII and OIII) and combined assigning to the RGB = SHO channels.
NGC 6888 La Nebulosa Creciente
NGC 6888, also known as the Crescent Nebula or Crescent Nebula, although it has always reminded me personally of a brain, but that is another matter.
This emission nebula is located very close to the heart of the Swan, it is very well accompanied by hydrogen, but in this field there is also a small almost transparent planetary nebula, which can be seen in the lower left part of the images, a transparent bubble This small nebula is commonly known as The Soap Bubble Nebula, or PN G75.5 + 1.7, and despite being small, if you zoom in, it can be seen without problems.
This image is obtained only through the use of narrow Bada filters, the palette used provides the colors that this object would more or less have, said palette is known as HOO.
Sh2-101 The Tulip Nebula
Sh2-101 is an emission nebula also known as "The Tulip Nebula", this galactic flower formed mainly by gas, crosses the skies of the northern hemisphere every summer, is part of a region rich in HII, it is very close to the micro quasar Cygnus X-1. It is undoubtedly a region full of wonders in the form of stars, dust and gas.
I remember balancing the stars, the nebula, and the background was a bit difficult but ultimately very satisfying.
This beautiful nebula is approximately 6000 a.l. away from us.
Sh2-115 y Sh2-116
Sh2-115 is a faint emission nebula, included in the Sharpless catalog since 1959. It is located in Cygnus, very close to Deneb, the brightest star in that constellation.
Sh2-116, also known as Abell 71, is the nebula at the bottom of this image. Although it is also known as PK85 + 4.1. This designation was given for its appearance as a planetary nebula, but more recently it has been revealed to be a small emission nebula.
With this I conclude the clipping of the constellation of the Swan, I hope you liked it, thank you very much for the visit.
What is your favorite nebula in this constellation? Because?
Until the next cut.
