The vdB152 Nebula (vdB152星雲) vdB152

This target, which includes vdB152 in the blue area and Barnard's dark lane extending north from there (below in the photo), is named Wolf's Cave. The surrounding Ha bands and nebulae are also beautiful.
To capture it with this telescope would require a mosaic of 6-8 panels, so I gave up this time. I wanted to at least capture the thin Ha bands that look like the colors around the blue area, but the exposure time was not enough.
The point this time was to emphasize the spiral thread structure around the bright star in the blue area.
I also assigned IR685 to G and B.

このターゲットは、この青い部分のvdB152とそこから北へ伸びる（写真では下）バーナードの暗黒帯をセットでWolf's Caveと呼ばれるObject名がついている。また周辺に広がるHaの帯や星雲が美しい。
この望遠鏡でそれを収めるには６−８パネルのモザイクが必要となり、今回は諦めた。せめて青い部分の周辺にある糸のように細いHaの帯を写したかったが、露出時間が全然足りなかった。
今回のポイントは青い部分にある明るい星の周りにある螺旋の糸の構造を強調して見た。
IR685をGとBにも割り当てて見た。
