The Starburst dwarf irregular Galaxy (星生成矮小不規則銀河) IC10
It belongs to the same local galaxy as the Milky Way, and is said to be the shortest star-forming dwarf galaxy at about 1.1 million light-years from Earth.
When Ha is added, the red region of the star formation site expands, but this time I first focused on the structure of this dwarf galaxy itself.
The galaxy is almost transparent except for the Ha region, but in test shooting, the galaxy was only faintly visible in B and G. Therefore, I assigned IR685, where the galaxy was dark, to RGB and developed it using the palette L-IRIGIB.
I tried Bottom Up the galaxy signal using ArcSinStretch and Generalised hyperbolic stretch.

天の川と同じ局部銀河に属し、地球から約110万光年にある星生成銀河としては最短距離に位置する矮小銀河だそうだ。
Haを追加すると星形成現場の赤い領域が広がっているのだが、今回はまずこの矮小銀河自体の構造
をポイントにして見た。
Ha領域以外はほぼ透明な銀河だが、テスト撮影でBとGはかすかに銀河が写っているだけだった。よって銀河が濃く写っていたIR685をRGBに割り当てL-IRIGIBというパレットにして現像して見た。
ArcSinStretchと Generalised hyperbolic stretchで銀河のシグナルをBottom Upしてみた。
