The southern windmill galaxy is seen through the National Observatory Management Agency (BPON) telescope. Some of the telescopes commonly used for research and astrophotography belong to BPON.
BPON itself provides telescope specifications that at least contain capabilities pointing or leads also follow the target well.
The goal is that certain dim target observations can be achieved to obtain the desired information.

Telescope Captures South Windmill Galaxy in Kupang
Abdul Rachman Coordinator of BPON Kupang explained that the picture is a good comparison of images black white on background and a colored foreground image of a galaxy called M83.
This black and white image was captured at BPON through the Takahashi refractor telescope. The telescope has a diameter of 106 mm with a focal length of 530 mm. The other side uses a telescope mount using the German equatorial type.
Quoting from the Space Science educational site, there is information that the image recording uses a CCD camera which has a resolution of 3326 x 2504 pixels. In addition, the technique for obtaining the image is in a simple way.

The trick is when the telescope is directed exactly at the target or galaxy M83, the holder needs adjustment. So that the telescope continues to follow the target, namely M83.
While the other stars remain in the same position in the image recorded for 10 minutes.
Color images can be captured well. For the sake of obtaining it apart from ability tracking and pointing which is good, also requires complete equipment.
The image has a larger size and focal length than BPON’s. The tool is complete with astronomical filters so that it produces a variety of colors.
When shooting galaxies using 4 filters that take up to 6 hours 16 minutes.
Data acquisition is complete, then it continues in data processing using several image processing software. Because it requires its own knowledge.
Getting to know the M83
M83 aka Messier 83 is more familiar with the Southern Pinwheel Galaxy or the south windmill galaxy and NGC 5236. M83 has a distance that is estimated to be about 15 light years.
As seen from Earth, M83 is in the constellation Hydra. In addition, it is much smaller than the Milky Way galaxy.

However, it produces stars at a high speed. Meanwhile, the pink colored dot is the birthplace of a new star.
The investment out is worth the payoff that can be seen in the comparison image. So that a simple black and white image is able to provide astronomical information.
This clearly shows that it is a spiral galaxy with a bar in the center.
