The Jellyfish Nebula

IC 443 is commonly called “The Jellyfish Nebula” due to its appearance. It is a “Supernova Remnant”, that is, the remains of a star that violently exploded 5,000 to 30,000 years ago. The spherical shape suggests that the explosion is still in progress, originating from the centre.

It resides about 5,000 light-years distance and is approximately 70 light-years in diameter. It is far too faint to be visible unaided, but, if it were, it would appear larger than the full moon.

The spherical blast wave from the explosion is thrusting (above) into the residing cloud of dust and gas in this galactic region. Below it, the blast wave is being absorbed by another smaller galactic cloud.

The Jellyfish Nebula is a favorite target for both amateurs and professionals. However, its history is still perplexing, debated.

I photographed the Jellyfish Nebula from my garden in Strasbourg France in mid-February 2024. 45 x 300 sec.

Jellyfish & Monkey Head Nebulae - During my last full session of image taking last year, I pointed my telescope at a familiar target as well as a new one... at the same time. Being able to get a wider field of view by using the Radian Raptor 61 opened up a lot of really neat imaging opportunities. Having captured the Jellyfish Nebula before. I wanted to get it in a wider fov and by doing so, I was able to include the Monkey Head Nebula in the frame. I had never captured this object before. One neat fact is that the Jellyfish Nebula is located in the Gemini constellation while the Monkey Head Nebula is located in Orion . 40 x 360s Dark, flat, bias and dark flat frames 800 ISO - Bortle 8 .

一角獣座 コーン星雲周辺

もうしばらくすると、おおいぬ座やしし座・おとめ座の系外銀河の季節になります。そうすると、鏡筒の主役がFSQからEdgeに交代します。

その前にFSQで取り残した星雲を撮っておきたいと思っています。まだまだいっぱいありますが。

欲張って隣のかたつむり星雲も入れようとしましたが、この画角では無理でした。右端ぎりぎりの青い×マークがかたつむり星雲。

まだ少し早いですが、この中心部分。コーン星雲とクリスマスツリー星団。先日の、Edge HD800+オフアキシスガイド予行演習中の１枚。

画面の上下を逆さまにすると、並んだ星がクリスマスツリーのイルミネーションに見えます。

一角獣獣座には、更にメジャーな星雲があります。

バラ星雲はこれが３度目。明るいけど、なかなか難しいです。今回は、構図を失敗。

もう一枚、FSQ106+レデューサーの写真。

頭から湯気を出してるくらげが、宇宙をプカプカ浮いてる感じが好きです。

とってもSF的。ちなみにSF大好きです。

硫黄からの発光は赤、水素は緑、酸素は青の色合いで表現されている。 くらげ星雲は上側で、比較的明るい弧を描く尾根状の発光星雲であり、垂れ下がる触手状のものを伴っている。 くらげ星雲は3万年以上前に爆発した超新星残骸IC443の一部で、つぶれた恒星の核の残骸である中性子星が内部に隠れているとみられる。 #ceres #nebula #cosmic #space #stella #hubble #space_telescope #comet #nasa #jaxa #sun #moon #mars #jupiter #earth #saturn #uranus #flare #corona #andoromeda #wise #messenger #astronaut #star #stars #alphacentauri #luna #cassini #system #galaxy https://www.instagram.com/p/Bweh5CIH14m/?utm_source=ig_tumblr_share&igshid=oeyo2ytjlf60

The Jellyfish Nebula - IC 443 The Jellyfish Nebula is a giant, and faint, supernova remnant in the Constellation Gemini . Back in the beginning of March I did a poll between two different processes. My simulated SHO ended up winning, but the is was my wife's, @ruthanne_holloway , favorite. This was a really neat target that I wish I would have respected more and gotten more time on. The problem was that there so many other great targets up at the same time! We always talk about the Summer / Fall Milky Way season, but the Winter Nebula season may actually be my favorite time to capture . For this post, I let IG do its crop thing and include the starless version . 50x240s & 5x300s (got lazy) 20 darks, 50 flats, 50 dark flats & 50 dark flats 800 ISO - Bortle 8 .

IC443. The Jellyfish Nebula is a supernova remnant. 30 X 6 mins in Ha and 12 x 6 mins of RGB each, taken last week. I will be posting the new Elephant Family video on Thursday after a couple of months or more. You can see it on my YouTube channel or on my website at https://www.davidcrane.co.uk Regards and stay safe. David https://www.instagram.com/p/CJ27pVFn-tB/?igshid=1mjlrajbh9pk5

The Jellyfish Nebula — hogewash The Jellyfish Nebula (aka IC443)) is a supernova remnant in the constellation Gemini. It’s roughly 5,000 light years from Earth.

Jellyfish Nebula - IC 443 The Jellyfish Nebula is a giant, and faint, supernova remnant in the Constellation Gemini. . Had a poll yesterday, and the winner is... the simulated HSO version! I took this data back at the beginning of February and I just realized I never posted it here, so I went back and tried some different processing. All three processes are available on my latest (March 7, 2021) on my blog - link on my profile. Included there also are starless versions, which would have been included here but Instagram did not like my image size :) Depending on the amount of data I can get over the next couple of weeks (small trip), I may end up posting one or both of the other processes here as well For this process, I took my image data, stacked it in Astro Pixel Processor three times, each time to extract a certain channel - Ha, Oiii and a simulated Sii (Ha - Oiii mono) and then recombine them as a color image using the Hubble palette, which places the Ha as green (normally red), Oiii as blue and Sii as red (also normally red...). APP allows you to change the algorithms of each individual channel to achieve the final color result you want. There are many different ways to do it and the way I did it here is the way I prefer. . 50x240s & 5x300s (got lazy) 20 darks, 50 flats, 50 dark flats & 50 dark flats 800 ISO - Bortle 8 .
