Here is a version of M33, the triangulum galaxy with a hygrogen alpha layer brought by my friend Hugo. You can view my friend work on his Instagram page, thanks to him for his help in this collaboration. We have mostly the same gear, so, making an HaRGB composition wasn't a big deal. We look forward to make more collaborations of this kind to achieve better results in our respective astrophotography.

Mais uma nebulosa planetária: NGC6781. Ela tem um formato de nebulosa anelar, lembrando muito a famosa M57 - “Nebulosa do Anel”, mas vista de um ângulo diferente. Seu formato quase circular, com regiões mais escuras e filamentosas, vem dos ventos estelares que se expandem em diferentes velocidades e direções, além da interação com o material interestelar ao redor. Sua estrela, no fim da vida, ilumina ionizando os gases ao redor que emitem cores de acordo com o elemento químico, o chamado espectro.

Another planetary nebula: NGC 6781. It has a ring-like shape, very reminiscent of the famous M57 – the “Ring Nebula”, but seen from a different angle. Its almost circular structure, with darker and filamentary regions, comes from stellar winds expanding at different speeds and directions, as well as from the interaction with the surrounding interstellar material. Its central star, at the end of its life, illuminates the nebula by ionizing the surrounding gases, which then emit colors according to the chemical element — the so-called spectrum.

Nebulosa planetária NGC5189. Uma nebulosa com formato fascinante! Ela lembra um S retorcido, um formato peculiar que provavelmente é resultado da interação entre estrela que está no fim da vida uma companheira invisível, ou seja, uma estrela binária. À medida que a estrela central da nebulosa expulsa suas camadas externas, o campo gravitacional da companheira influencia o fluxo do gás, criando essas formas simétricas e curvas.

Planetary Nebula NGC 5189. A nebula with a fascinating shape! It resembles a twisted "S" — a peculiar structure likely caused by the interaction between a dying star and an invisible companion, meaning a binary star system. As the central star of the nebula expels its outer layers, the gravitational pull of the companion influences the gas flow, creating these curved and symmetrical forms.

Nebulosa dos Jatos Gêmeos (M9-2) ou Minkolsky's Butterfly Nebula. Uma nebulosa planetária bipolar bem pequena no céu noturno. A maioria das nebulosas planetárias possuem formato circular. Porém nesse caso, é uma estrela binária que está muito próxima da irmã que está em seus últimos momentos de vida e expele suas camadas externas. Assim, forma-se dois jatos quase que perfeitamente alinhados e simétricos. Um formato diferenciado. Essa captura foi feita no céu da Chapada dos Veadeiros, um dos melhores céus para observação astronômica do Brasil!

Twin Jet Nebula (M2-9), also known as Minkowski’s Butterfly Nebula. A small bipolar planetary nebula in the night sky. Most planetary nebulae have a circular shape. However, in this case, a binary star is orbiting very close to its companion, which is in the final stages of its life and is expelling its outer layers. This process creates two jets that are almost perfectly aligned and symmetrical — resulting in a very distinct and unique shape. This capture was taken under the sky of Chapada dos Veadeiros, one of the best places for astronomical observation in Brazil!

NGC6537 ou nebulosa da aranha vermelha é uma nebulosa planetária localizada a cerca de 4.000 anos-luz da Terra na constelação de Sagitário, próximo à direção do centro galáctico e com bastante h-alpha próximo à ela. A NGC6537 é uma nebulosa planetária bipolar com uma aparência lembra um X ou uma aranha com pernas flamejantes, formada por uma estrela em seus momentos finais. Seu núcleo é uma das estrelas centrais mais quentes conhecidas em nebulosas planetárias, com temperatura superior a 500.000 K, o que contribui para a intensa iluminação do material ao redor.

NGC 6537, or the Red Spider Nebula, is a planetary nebula located about 4,000 light-years from Earth in the constellation Sagittarius, near the direction of the galactic center and surrounded by strong H-alpha emission. NGC 6537 is a bipolar planetary nebula with an appearance that resembles an "X" or a spider with flaming legs, formed by a dying star in its final stages. Its core is one of the hottest known central stars among planetary nebulae, with a temperature exceeding 500,000 K, contributing to the intense illumination of the surrounding material.

É muito interessante quando tiramos uma foto de uma porção maior do céu (menor distância focal). Muitos objetos tendem a aparecer. Nesta captura da Nebulosa da Galinha Correndo (IC2714), também é possível ver a NGC3579 e outros objetos mais, dentre outras nebulosas e grupamentos estelares. Infelizmente, devido a um erro de configuração que só vi depois, as capturas foram feitas com gain 0, o que reduziu muito o brilho e aumentou o ruído e acabei tendo que fazer um corte grande nas laterais. Mas ainda assim, gostei bastante do resultado! Segunda imagem mostra os objetos com anotação.

It's always fascinating when we photograph a wider portion of the sky (using a shorter focal length). Many deep-sky objects tend to reveal themselves. In this capture of the Running Chicken Nebula (IC 2714), you can also spot NGC 3579 and several other objects, including additional nebulas and stellar clusters. Unfortunately, due to a configuration error I only noticed afterward, the images were taken with gain set to 0 — which significantly reduced brightness and increased noise, so I ended up cropping a large portion of the edges. Still, I'm quite happy with the final result! The second image includes annotations highlighting the objects in the field.

IC 4406 é uma nebulosa planetária localizada a cerca de 2.000 anos-luz de distância na constelação do Lobo, a é uma nebulosa planetária que parece retangular, mas trata-se na verdade de uma estrutura complexa com anéis de gás e poeira expelidos por uma estrela em seus momentos finais de vida que possivelmente interagem com uma anã companheira. A forma intrigante pode ser explicada pela nossa linha de visão: estamos olhando para uma nebulosa bipolar de frente, onde jatos de gás e poeira escapam pelas extremidades enquanto densas faixas de material obscurecem o centro. Com equipamentos sensíveis, é possível captar detalhes sutis dessa despedida estelar.

IC 4406 is a planetary nebula located about 2,000 light-years away in the constellation Lupus. It appears rectangular, but it is actually a complex structure with rings of gas and dust expelled by a dying star, possibly interacting with a companion white dwarf. Its intriguing shape can be explained by our line of sight: we are viewing a bipolar nebula face-on, where jets of gas and dust escape through the ends while dense bands of material obscure the central region. With sensitive equipment, it is possible to capture the subtle details of this stellar farewell.
