3 Salt And Pepper Clusters (三つの塩胡椒星団) M52,37,11

While I was shooting, I looked at Stellarium and saw two Salt and Pepper Clusters, so I searched to see if there were any others and found that there were a total of three Salt and Pepper Clusters registered on Stellarium.
I thought I could take pictures of all three at this time, so I started this mini project to compare them.
All the shooting equipment was the same telescope, cooled camera, and filters.
The shooting parameters were all the same: Gain 200, Offset 5, exposure time 40 minutes.
The editing parameters were also the same, with various process settings.
Only the saturation was manually adjusted to almost the same value.

Please consider this for yourself.

撮影中にStellariumを眺めていると２つのSalt and Pepper Clusterがあったので、他にもあるか検索すると全部で３つのSalt and Pepper ClusterがStellariumに登録されていた。

この時期に3つとも撮れるので比較しようと思い、このミニプロジェクトを立ち上げて見た。

撮影機材は全て同一の望遠鏡,冷却カメラ,フィルター

撮影パラメータはGain200,Offset 5,露出時間40分で全て同一

編集パラメータも各種プロセスの設定は同一

彩度だけ手動でほぼ同一値で調整

みなさんご自身の考察してみてください。
