The Omega Centauri Cluster (オメガ・ケンタウリ星団) NGC5139

One of last year's challenges was ``I want to be able to see the stars of the cluster over a wider area.''
I added Signal to solve this problem.
When the stars are brought out this far, this globular cluster looks like an ellipse rather than a circle.
I feel like I achieved my goals, so this season is over.
Normally, I only adjust the brightness, saturation, and halo to adjust the star colors after performing color calibration, but this time I was inspired by HUBBLE's "CORE OF OMEGA CENTAURI" and greatly emphasized the star colors. .
I think it's easier to see the distribution of red and blue stars this way.

昨年の課題の一つであった、「もっと広い範囲まで星団の星が見れるようにしたい。」
という課題の決着のためSignalを追加して見た。
ここまで星を出すと、この球状星団は円ではなく楕円に見える。
自分の目標には達成できた感じなので、今シーズンは終了。
普段星の色はカラーキャリブレーションを行った後は輝度と彩度とハローの調整する程度だが、今回はHUBBLEの”CORE OF OMEGA CENTAURI”に刺激され、星の色を大幅に強調して見た。
この方が赤と青の星の分布が見やすい感じかな。
