NGC 6210, sometimes also known as the Turtle Nebula, [4] is a planetary nebula located in the constellation Hercules, approximately 5.4 ± 1.3 kly from the Sun. [2] It is positioned about 38° above the galactic plane at a vertical distance of about 3.3 kilolight-years (1 kpc) and thus has little extinction from intervening interstellar dust. [5] .

2024年7月3日 · NGC 6210 is the last gasp of a star slightly less massive than our Sun at the final stage of its life cycle. The multiple shells of material ejected by the dying star form a superposition of structures with different degrees of symmetry, giving NGC 6210 its odd shape.

2010年10月18日 · NGC 6210 is the last gasp of a star slightly less massive than our Sun at the final stage of its life cycle. The multiple shells of material ejected by the dying star form a superposition of structures with different degrees of symmetry, giving NGC 6210 its odd shape.

NGC 6210 is about 6'600 light-years away. The nebula measures 1.6 light-years from the very top of the turtle-shaped form to the tip of the bottom. The inner nautilus shell is about 0.5 light …

1998年10月22日 · The remarkable features of this nebula are the numerous holes in the inner shells with jets of material streaming from them. These jets produce column-shaped features that are mirrored in the opposite direction. The multiple shells of material ejected by the dying star give this planetary nebula its odd form.

NGC 6210 is a Planetary Nebula in the Hercules constellation. NGC 6210 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

NGC 6210 is a Planetary Nebula located in the constellation of Hercules in the northern hemisphere. NGC 6210's distance from Earth is 6,500.00 light years. NGC 6210 is called NGC 6210 in the New General Catalogue (NGC).

Located in Hercules, NGC 6210 is a very small (only 15 x 20 arc sec) but bright (mag. 8.4) planetary nebula. In the late 16th century it was originally identified as a star but Wilhelm von Struve realized it's nebulous nature in 1825 while he was searching for double stars. It is about 6000 light years distant.

撮影メモ： ヘルクレス座β星から北東に約4度のところに位置する小型の惑星状星雲です。 東西方向に伸びた楕円形をしており，長径は約20秒ほどです。 9.7等と明るいので，小望遠鏡で …

2021年6月10日 · 惑星状星雲の御多分に漏れず、単位面積当たりの明るさが大きいので、この写真では1コマあたりの露出を2秒に抑えて多数枚撮影し、これをコンポジットした後にRegistax6でウェーブレット処理。 さらに最大エントロピー法で画像復元をするという、惑星写真と同じ処理方法を取っています。 加えて、周辺の淡い部分を少しでも表現するため、ステライメージ9にて、レベル調整やデジタル現像を組み合わせて周辺の淡い部分を持ち上げた後、 …
