Imagine losing in Showdown.

Challenging to a rematch.

Losing worse than the previous time so you disconnect.

Imagine being so sad.

Accept your beating like Pokemon trainer or forfeit for real don't just disconnect thinking I won't wait out that 300sec timer LOL

NGC7380/SH2-142 aka "The Wizard Nebula". An active Star forming region with an open Starcluster. Its around 7200 light-years away from us in the constellation Cepheus and has a total radius of around 100 light-years.

Reworked Version, new picture post processing workflow! Hope you enjoy 😁👍🔭

That object is hard to get and it took us 6.5 Hrs total integration time. (300sec single frames plus darks, flats and bias frames).

We made that picture with an 8"F5 Newton telescope and an astromodified DSLR camera.

オリオン座 M42 & M78星雲

月明かりが強くなってきたので、通常撮影はあきらめ、光害カットフィルターを使っていくつかテストをしています。

一つ目は、初分子雲です。

M42 オリオン座大星雲とその周囲の分子雲

Optics; Takahasi FSQ106+ExtenderQ1.6 f848mm(F3.6) Camera; Nikon810A+BAADER UHC-S Mount; Vixen SXP Guide; Kowa 100mm guidescope, QHY5L-Ⅱ. PHD2guiding Exposure; ISO1600 600secx7frame, 300sec× 4frame, 60sec×4frame ( total exposure 94minutes) Image Processing; Stellaimage 8, Photoshop CC+Color Efex Pro4   Dark10fr Flat10fr, no triming Date; 2019/12/4 @Shukuno Temperature 0.3℃, Humidity 87%

The molecular cloud is a collective term for debris or gas floating in outer space between stars. I took a picture of the great Orion nebula Messie42 and molecular clouds surrounding M42. The molecular clouds are faintly visible. Messie42, the great Orion nebula is realy beautiful. It looks like ＨＡＧＯＲＯＭＯ、a costume worn by a heavenly woman in Japanese folk tales.

オリオン座M42大星雲周囲の分子雲を狙いました。淡いですが、M42の周囲を分子雲が取り巻いていました。

分子雲は、星と星の間の宇宙空間に漂う星間ガスの総称です。ここからあらたに星が誕生すると言われ、星のゆりかごみたいなものでしょうか。

分子雲を撮影するには、光害のない暗い空でないと難しいと思っていて、これまで手を出したことはありませんでしたが、雑誌などで比較的空が明るいところでもきちんと撮影すれば撮れると書いてあって、今回初挑戦してみました。

画像処理の段階でかなり暗い部分を強調するので、フラット補整の勉強もし直しました。最終の画像処理で、Color Efex Pro4の30日無料体験版も使ってみました。難しい画像処理ソフトですが、使いこなせるようになりたいです。

もう一つのテストは、まだ十分に使えていない冷却CMOSカメラ。これから撮る予定の系外銀河の準備です。

オリオン座 M78 散光星雲 Messie 78 is the Ultraman' hometown

Optics; Takahasi FSQ106 f530mm(F5.6) Camera; ZWO ASI294MCpro+IDAS NB1 Mount; Vixen SXP Guide; Kowa 100mm guidescope, QHY5L-Ⅱ, PHD2guiding Gain 200　Exposure 300sec x21frame (total exposure 105minutes) Image Processing; Stellaimage8, Photoshop CC+Color Efex Pro4 Date; 2019/12/8 @Shukuno Temperature -0.5℃, Humidity89%

I took Messier78, refractory nevil of Orion. M78 is the hometown of Ultraman, the hero of Japanease special effects movie and TV.

真ん中の青い星雲がM78。左上の赤い部分は三ツ星を取り巻くバーナードループの一部。右下は三ツ星の一番左の星からの光条です。ダーク・フラット補整ができていないこと、最終処理でこれもColor Efex Proを使ったのでノイズがひどいのですが、冷却CMOSは何とか使えそうです。

M78星雲、ウルトラマンの生まれ故郷。始めて撮影できました。

ウルトラマンシリーズの中では、M78は銀河系から300万光年離れた星雲と言われたそうですが、本物のM78は地球から1600光年離れていて、もっと近くにあります。

星雲だと、いくらウルトラマンでも住めないですよね。

On this night the stars aligned (pun intended) for a brief moment of clarity just long enough to snap a few photos. Every shot I've ever seen from this location is taken further back in the cave and you cannot see shark fin rock, so I wanted to see if I could capture the entire shark fin in my photo to make it a little different. Great time shooting on this night along side John Fox, and to make it even better we had the entire place to our selves. Incredible night/morning. Hope you enjoy.

初めてのTumblr

久しぶりのブログ作成です。

このブログの使い方がまだよく分かりませんが、宿野で撮った星の写真を保存していきたいと思っています。

先日、夜露に濡れる天体撮影用に用意したmouseのノートパソコンで、ステラショットのライブビューが動きませんでした。後で見直すと、二コン810Aのライブ設定が静止画ではなく動画になっていました。

ということで、この日初めてmouseのノートパソコンを使えました。m-Book X400です。

ぎょしゃ座 M38・IC405（まが玉星雲）・IC410付近

Optics; Takahasi FSQ106+645QE0.73RD f380mm(F3.6) Camera; Nikon810A+BAADER UHC-S Mount; Vixen SXP Guide; Kowa 100mm guidescope, QHY5Ｌ-Ⅱ, PHD2guiding Exposure; ISO1600 300sec x31frame (total exposure 2hours 35minutes）　　　　　　Image Processing; Stellaimage 8, Photoshop CC Dark10fr Flat10fr, no triming Date; 2019/11/23 @Shukuno Temperature 7.5℃, Humidity 83%

東天で南中前まで２時間撮影を終了したところで、星に髭が生えてて、バーティノフマスクが付いていたことが判明しました。

折れそうになりましたが、気を取り直して南中後反転させて取り直し。

赤い星雲が十分に写らず、２時間半の露出でも、まだ足りないのかもしれません。構図は、満足できました。

こんな調子で失敗続きですが、星屑拾い、始めたいと思います。

星の写真は全く独学なので、読まれた方、何でもアドバイスいただければ嬉しいです。
