The Robin’s Egg Planetary Nebula (ロビンの卵)　NGC1360

Target shot with Duo Band Filter for the first time 3 years ago.
This time I tried inserting Ha into LRGB, but the Ha area was not beautiful at all.
There is a more red area in the center, but it is lost to the blue.
Challenges for next time.

3年前に初めてDuo Band　Filterで撮影したTarget。

今回はLRGBにHaを差し込んでみたが、Haの領域が全然美しくない。

中央にもっと赤い領域があるのだが、青に負けてしまっている。

次回への課題。
