(360mm) The RCW35 Nebula and Pencil Nebula (RCW35,RCW36,RCW37) WMBNC 18 : Astropical

Astropical

This site is for Astronomy Studies in the Tropics. I'm based in East Pattaya, Thailand, 12.934N, 100.918E, between the sun's northern limit and the Equator. The big advantage of this location is that you can observe both northern and some southern stars at the same time. And it's never cold... lol. I hope to introduce you to the unique celestial opportunities available from this area. Enjoy your observations!! Taro Seki Astropical.uk

The RCW35 Nebula and Pencil Nebula (RCW35,RCW36,RCW37) WMBNC 18

WMBNC 18: Catalog of large nebulae in the winter Milky Way 18

All nebulae except RCW35 in the upper right can be captured in the field of view with RC10 + MFT, but RCW35 cannot be captured and I chose this FOV because I wanted to keep a catalog of the lightning-like supernova remnant that cuts through the center from north to south.

The bright nebula in the upper left is RCW36, and the Pencil is RCW37.

Due to the effects of PM2.5, the overall image is blurred and the background is dirty, but I still have a lot to learn to put together this gradient nicely.
Blue and red molecular clouds are spread out in the background, and I had no idea how to separate the background.

I hope they release MARS data from this area soon.

WMBNC 18: 冬の天の川の中にある大きな星雲のカタログ18

右上のRCW35以外はRC10＋MFTでも画角に収まる星雲だが、RCW35は収まらないのと中央を北から南に切り裂く稲妻の様な超新星残骸をカタログとして残しておきたかったので、このFOVを選んだ。

左上の明るい星雲がRCW36、PencilはRCW37。

PM2.5の影響でなんか全体的にボケて背景も汚いが、まだまだこのGradientを綺麗にまとめるには勉強不足だな。

背景に青と赤の分子雲が広がっていて、どうやって背景分離して良いのかさっぱり判らなかった。

早くこの周辺のMARSデータがリリースされないかな。
