The **Bubble Nebula** (NGC 7635) is a striking emission nebula located about **7,100 light-years away** in the constellation **Cassiopeia**. It gets its name from the large, bubble-like structure formed by the powerful stellar wind from a massive, hot **O-type star** at its center. This wind pushes surrounding gas outward, creating a glowing shell of ionized hydrogen. The nebula spans roughly **7 light-years across** and is illuminated by the intense radiation from the central star, making it a beautiful and dynamic example of the interaction between stars and the interstellar medium.

47 Tucanae (NGC 104) ou apenas 47 Tuc é um aglomerado globular situado na constelação de Tucana. Está a de cerca de 16 700 anos-luz de distância da Terra, e tem 120 anos-luz de diâmetro. Pode ser visto a olho nu, e é brilhante o suficiente para ganhar uma designação de Flamsteed com uma magnitude visual de 4,0. É apenas uma de um pequeno número de características com essa designação do céu do sul.
47 Tucanae foi descoberto por Nicolas Louis de Lacaille em 1751; a sua localização muito ao sul tem escondido de observadores europeus até então. O aglomerado aparece aproximadamente com o tamanho da lua cheia no céu em condições ideais.
É o segundo aglomerado globular mais brilhante no céu (depois de Omega Centauri), e é conhecido por ter um núcleo muito brilhante e denso. Ele tem de 22 pulsares milisegundos conhecidos, e pelo menos 21 estrelas retardatárias azuis (blue stragglers) perto do centro.[4]
47 Tucanae está incluído no Catálogo Caldwell de Sir Patrick Moore como C106.
NGC 104 concorre com NGC 5139 (Omega Centauri) para o título: O mais esplêndido Aglomerado Globular no céu. NGC 104 tem duas características em seu favor. Ele é arredondado e tem um centro mais compacto. No entanto, devido à localização, mais observadores vão para NGC 5139.

This was is an image created from two sessions a month apart, at different locations, with different telescopes: A Vixen ED80SF (July HaOiii) and a Tele Vue NP101is(August, SiiOiii). This was first light on the Tele Vue NP101is. Since they had different resolutions I had to go to astronometry.net to get the proper orientation and the center coordinates from the July HaOiii image. I plugged these coordinates into NINAs target instruction set for the SiiOiii image in August. In Pixinsight I used Star Alignment to do final alignment between the images out of WBPP before processing through Pixinsight.

Astronomical objects have formal names according to the catalogue they are listed in … for example the Messier Catalogue, NGC (New General Catalogue), Caldwell Catalogue, Sharpless Catalogue, etc., etc., etc. But many astronomical objects have been given more common names by astronomers based on sort of what the object resembles … for example The Witches Broom nebula, the Tulip Nebula, Pac-Man nebula, etc, etc. A type of astronomical pareidolia you might say.
So the object pictured above is actually NGC 7380 … but it is more commonly … and perhaps more widely … known as the Wizard Nebula. Why? Well, if you look closely up there on the left you can see (perhaps 😀) a wizard’s pointed hat, perhaps a face and nose, farther down his flowing robes, and maybe even a couple of hands casting a spell. All adding to the fun and wonder of this amazing hobby. Enjoy!
This photo is a result of 633 ten second images taken with the Seestar S50, stacked and processed in PixInsight, with help from NIK Collection plugin for Photoshop, Topaz Sharpener, and ProDigital Software’s Star Spikes 4.
The Wizard Nebula is approximately 7200 light-years away from Earth, has an apparent magnitude of 7.2, and is situated in the constellation Cepheus.

This HDR image shows the bright nebula in a sea of colourful stars against a background of red from dust and HA emissions. The stars in this image range from the brightest ( bottom right, HD 56501 ) at magnitude +7.7 to more than +22. HDR capture and processing allows all of the stars to be portrayed in colour without any burnt-out highlights. The colours of the stars and nebula are as close as I can get them to the "true colours" using a "daylight colour balance" and allowing for the extinction of blue-green due to atmospheric absorption/scattering ( mean altitude during capture ~ 60deg ).
The blue star in the centre of the bubble of expanding stellar material is HD 56925 ( WR7 ) - a massive, unstable and short-lived Wolf-Rayet star that one day will detonate in a supernova.

A classic process for a classic target, one of the most beautiful and accessible nebula.
I tried to reveal all the complexity on the nebular gases.
It was a difficult object on my old location because theri max altitude is 53º and it was poorly visible. Now in Montsec it's still at 53º max but with clear horizon it was possible to add close to 20 hours of end integration.
"The cluster and nebula lie at a distance of some 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses."

There was a nice series of events on Jupiter this past Friday morning (February 26, 2016) and while the seeing conditions were only fair I was able to get some images of the moons Europa and Io passing over and near to the disk of Jupiter with its Great Red Spot.
The moon Europa is visible just off to the right side of Jupiter while the shadow of Io is nearly centered on the planet itself (in fact, you can see a faint hint of Io just to the left of its shadow).
Image capture was done with a Celestron 9.25” EdgeHD telescope and a ZWO ASI178MM-Cool camera with a set of Baader RGB filters.
Image processing was done with Autostakkert!, Registax, PixInsight, and Photoshop CC2015.

LDN 1251 is a very faint nebula in Cepheus. Visible in the far lower left part of this image is the ruby red colored Carbon Star NIKC 5-20. A carbon star is a late-type star similar to a red giant (or occasionally to a red dwarf) whose atmosphere contains more carbon than oxygen; the two elements combine in the upper layers of the star, forming carbon monoxide, which consumes all the oxygen in the atmosphere, leaving carbon atoms free to form other carbon compounds, giving the star a sooty atmosphere and a strikingly ruby red appearance. (Credit Wikipedia). Also shown are several YSO's (young stellar objects), and several very distant galaxies.

Orion a.k.a. Messier 42, the most famous nebula in the night sky in both the northern and southern hemispheres, can be found in the constellation Orion and can be seen (literally) from August to April. Orion can be seen with the naked eye from low light pollution locations, but a simple pair of binoculars is more than enough to be observed in the middle of Orion's Sword.
M42 is about 1300 light-years away from Earth, has an apparent diameter of 12 light-years, and is considered by far one of the most popular targets in astrophotography, along with Andromeda Galaxy.

Out of all the images I have processed, this one seems the most alien. Galaxies have familiar shapes and colors, planetary nebulae are too abstract. This almost looks familiar, but at the same time is something I could never imagine.
Anyway, details!
I created a four panel mosaic for each color channel. HLSP did a great job with the mosaics, but I wanted to practice myself. I think I did better with the seams, and got rid of some pesky artifacts.
Everything was from Hubble's Wide Field Camera 3 (WFC3)

The Crab Nebula is a supernova remnant that lies some 6500 light years away in the constellation Taurus. The nebula was discovered in 1731 and has the 1054 supernova event recorded by Chinese astronomers as it's progenitor. At the heart of the nebula is the Crab Pulsar, which is a neutron star some 18 miles across and spins 30 revolutions per second. It emits very bright pulses of electromagnetic radiation from gamma rays on down to low energy radio waves. It's one of the brightest sources of high energy photons in the sky. The inner portion of the Crab Nebula has been shown to continue to expand, driven by the persistent pulsar wind.

From Wikipedia:
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of the explosion, the supernova would have appeared brighter than Venus in the sky, and visible in the daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800light-years, a recent determination of 2400 light-years is based on direct astrometric measurements.The distance estimates affect also the estimates of size and age.

今回はデジとモノクロHaのミックスですが、普通にPIのLRGB合成でHaをLとしてしまうと画像がピンクになると言う問題があるのでPIのstar alignで位置だけ合わせて合成はCSでやりました。
