The Pencil Nebula (ペンシル星雲) NGC2736
This is also a nebula that ended halfway through last year.
Last year, the gardener was kind enough to cut off the bushy branches that were blocking the light from the streetlights, so I couldn't compete.
This year, almost every day, I begged him, "This tree will cut its own branches, so don't mess with it."
The light from the streetlights has been avoided in a good way, but it seems that the light pollution in the low latitude south was severe in the first place.
I managed to see the shape in the 3rd shooting this year, but it's no good if it's so blurry.
Maybe I'll try again when I shoot on an expedition.
これも昨年中途半端に終わった星雲。
昨年は庭師の方が親切にも街灯の光避けになったいたフサフサの木の枝をバッサリ切ってくださり、太刀打ちできなかった。
今年は毎日のように「この木は自分で枝を切るから、いじらないでねー」とお願いしておいた。
街灯の光はいい塩梅に避けられるようになったが、そもそもの低緯度の南の光害は厳しかったようだ。
今年も3回目の撮影でなんとか形は見えたが、こんなにモヤモヤじゃダメだな。
遠征撮影時に再トライかな。
