The Cygnus Loop (radio source W78, or Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across. [1] Some arcs of the loop, known collectively as the Veil Nebula or Cirrus …

Sh2-103又称天鹅圈。 NGC 6960，西面纱，是西边的残骸，也称为女巫的扫帚，位置在 赤经 20 45 58.1 赤纬 +30° 35′ 43″ (2000.0分点)。 它是在星云最西边的 NGC天体 (以 赤经 来看) ，有时也用这个标示 (NGC 6960)做为整个星云的代表。 这三个明亮的区域构成东面纱。 NGC 6992是位于环东北部边缘的HI壳，它的位置座标是 赤经 20 56 19.0 赤纬 +31° 44′ 34″ (2000.0分点)。 NGC 6995位于最南边，位置座标是 赤经 20 57 10.7 赤纬 +31° 14′ 07″ (2000.0分点)。 IC 1340的 …

Well, this is what I have been working on during the past week. My biggest project to date - The Mighty Veil Nebula. I shot this object last year as separate parts - East and West. However it is so be...

2021年5月20日 · NGC 6960は、Sh 2-103・超新星残骸、網状星雲の西側円弧の一部です。NGC 6960の中心にある4等星の輝星は、52 Cygで地球からの距離は63.1pcと網状星雲（500〜1000pc）よりはるか手前にある星雲とは無関係の恒星です。

The Cygnus Loop or the Filamentary Nebula refers to the visible structure of a supernova remnant located in Cygnus. The progenitor star was 20 times more massive than the Sun and exploded between 10,000 and 20,000 years ago. The nebula is quite large at 120 light-years in diameter (3 degrees) and approximately 2400 light-years across.

Sharpless 103, Sh2-103 is the gigantic supernova remnant in Cygnus know to most of us as the Veil Nebula or Cygnus Loop. The Supernova remnant that makes up Sharpless 103 exploded between 5000 to 8000 years ago and now covers about 3 …

2021年7月7日 · Sh2-103: Cygnus Loop - Two Panel Mosaic - posted in Experienced Deep Sky Imaging: Here we have my second attempt of a two panel mosaic. I decided on the Cygnus Loop in the constellation of Cygnus. I dialed the reducer back to try to get rounder stars on the edges.

Sh2-103, the Cygnus Loop, is a large supernova remnant in the constellation of Cygnus. It lies about 2’400 Ly from Earth and is about 120 Ly in diameter. It is about 20’000 years old. The scond image is annotated with its key visual components.

2021年9月23日 · Sh2-103（網状星雲/はくちょう座ループ）の位置や星図と天体写真や撮影データ。 季節は夏で「はくちょう座」にある超新星の残骸。 位置はε星アルジャナーの近くで「赤経20h50m32.5s/赤緯+30ﾟ55’24″」明るさは8～9等級で大きさは「180′」適正焦点距離は150 ...

Located roughly 2,400 light years away in the constellation Cygnus, the Cygnus Loop (or Veil Nebula Complex) is a cloud of heated and ionized gas and dust. The colourful appearance in this supernova remnant is generated by variations in the temperatures and densities of the chemical elements present.
