Last year, I took a temporary shot of the filter and HyperStarC6 as a test, but since it was a Target that I had never shot before, I tried shooting it.

The center was unusually bright like a trapedium, so I changed the exposure time several times and finally decided on an exposure time of 30 seconds and shot 120 frames.

Total exposure time 1 hour.

The open cluster to the left of the center is NGC6530, and the globular cluster NGC6533 is to the lower right of the bright star in the center.

I would like to take a picture of 6533 so that I can understand the shape of the globular cluster.

It's a beautiful nebula.

昨年フィルターとHyperStarC6のテスト様に仮撮影したが、単独では本撮影をしたことがないTargetだったので、撮影してみた。

中心部はTrapediumの様に異常に明るく、何パターンか露出時間を変えて最終的に30秒の露出時間に決め、120Frame撮影してみた。

総露出時間 1時間。

中心の左ある散開星団がNGC6530、中心の明るい星の右下にあるのが球状星団のNGC6533。

この6533を球状星団の形が解る様に撮ってみたいな。

綺麗な星雲だな。
