Name: Sculptor Galaxy, NGC 235
Type: Spiral galaxy
Distance: ~11.4 million of light-years
Diameter: ~70.000 light-years  Apparent magnitude: 8
Constellation: Sculptor 
The Sculptor Galaxy, also known as the Silver Coin or Silver Dollar Galaxy, NGC 253, is an intermediate spiral galaxy in the constellation Sculptor. The Sculptor Galaxy is a starburst galaxy, which means that it is currently undergoing a period of intense star formation.
The galaxy was discovered by Caroline Herschel in 1783 during one of her systematic comet searches. About half a century later, John Herschel observed it using his 18-inch metallic mirror reflector at the Cape of Good Hope. He wrote, “very bright and large (24′ in length); a superb object…. Its light is somewhat streaky, but I see no stars in it except 4 large and one very small one, and these seem not to belong to it, there being many near…”
As one of the brightest galaxies in the sky, the Sculptor Galaxy can be seen through binoculars and is near the star Beta Ceti. It is considered one of the most easily viewed galaxies in the sky after the Andromeda Galaxy.
The Sculptor Galaxy is a good target for observation with a telescope with a 300 mm diameter or larger. In such telescopes, it appears as a galaxy with a long, oval bulge and a mottled disc. Although the bulge appears only slightly brighter than the rest of the galaxy, it is fairly extended compared to the disk. In 400 mm scopes and larger, a dark dust lane northwest of the nucleus is visible, and over a dozen faint stars can be seen superimposed on the bulge.

This image is the result of teamwork. The images were acquired by my friend Irineu Felippe de Abreu Filho and kindly provided for me to carry out the processing. I leave here my thanks for the opportunity.
The images were taken in three sessions. On 7/21/2017 9 images were captured and 7/24/2017 26 images were captured in the rural area of Padre Bernardo – GO – Brazil. On 07/17/2018, a year later, another 49 images were captured in the rural area of São Romão – MG – Brazil.
