This image captures a series of five circular Sharpless HII emission objects located 8000 light-years away in the constellation of Orion. The three main objects, right to left, are Sh2-254, Sh2-257, ...

SH2-254, 255, 256 and 257 "The Other Orion Nebula" are a group of nebulae 8000 light-years distance in Orion. On 3/12/2022. The Moon was about 70% illuminated and only about 20 degrees from my target. It was the coldest, windy night this year. I had to throw out about 15% of the subs I took because of wind vibration.

2020年3月21日 · Located approximately 8,000 light years distance in the constellation Orion the Hunter is a complex of 5 separate objects. These celestial wonders are identified in the Sharpless catalog as Sh2-254 through 258. The brightest of these are Sh2-255 and Sh2-257 and optically lie close to the larger but more diffused Sh2-254.

Here is a complex of strong HII emission nebulae, some 8,000 light-years from Earth in Orion. I used the C11" @ f/10 to try and get a good close-up with some detail despite the intensely bright moon during this imaging session. The danger of this is …

SH2-254 is the largest of a group of Sharpless objects in a small area in the sky. Below SH2-254 is SH2-257, and SH2-255. The two smaller ones are SH2-256 and SH2-258. Not much here for a wider field of view but the larger telescope can define the structure very well. The nebula complex picks up best with the hydrogen-alpha filter.

2021年10月12日 · Sh 2-254〜258は、Sh 2-257とSh 2-255の間を中心とする若い大質量星星団と星間雲で構成される星形成複合体です。 Sh 2-258からさらに南西側明るい6等星HD 42954の下（南）にSh 2-258Bと呼ばれる小さな領域があり、赤外線で観測すると258から258Bに向かってフィラメント状 ...

This image shows a complex of H II regions located at 2460 parsecs (8,000 light years) away from Earth in the Perseus Arm, at the southernmost part of the Gemini OB1 association, in the constellation Orion.

2023年11月19日 · 中央の星雲はSh2-257，右の大きいが他に比べ薄い星雲はSh2-254です。 257の下が256、255の右（東側）の小さく淡い星雲が258です。 SH2-254～258が画像内ですぐ近くにあるだけでなく、空間的にはすべて地球から約 6,500 光年の距離にあります。

This nebula complex is embedded within the 27000 solar mass GEM OB1 molecular cloud located along the galactic plane with most of the mass concentration between bright nebulas Sh2-255 and Sh2-257.

2008年5月29日 · Sh2-254 through Sh2-258 - posted in Experienced Deep Sky Imaging: Left to right they a Sh2-258, Sh2-255 (also known as IC 2162), Sh2-257, Sh2-256 and Sh2-254 the biggest but faintest of the bunch.
