101 Must Know Things of the Earth: NGC 6781

The planetary nebula NGC 6781 is in the constellation Aquila the Eagle. But even though this star image is the 22nd largest among the 88 constellations, you won’t see any Messier or emission nebulae in it. In fact, while he was in the Milky Way, there were some twinkling star clusters.

The NGC 6781 doesn’t accomplish everything, but it’s a good target for amateurs with small telescopes. This planet is about 3,500 light -years away and has 2 light -years in diameter. As with all of them, however, the swell continues to increase until it is farther away from the white -white center for the light of the star to separate it. At that point, it will just fade from view.

To obtain NGC 6781, point your telescope 3.8 ° north-westwest of the 3.4 Delta (δ) Aquilae. What you can see is a nearby gas bubble thrown by a star that produced energy like our Sun, but it took a long time to stop adding hydrogen to helium in it. his teacher.

Through a 6-inch telescope at 100x, the 11.4 NGC 6781 stands out well against Aquila’s full economy side. With large instruments, you can see that the disk is not very thin and is a little oval. If you have a good view (continuity of space) in your focus area, you will find that the center of the nebula is much darker than its surroundings.

If you can look at this planet through 14-inches or larger, you will see how many buildings are in its thick circle. At higher powers, you will see small, dark spots on his face. The central star of the Earth, a little blue -white dwarf, shines at magnitude 16.2, so don’t delay the search.
