The Silver Silver Galaxy (銀銀銀河) NGC891

While I was waiting for the main target, I took a picture as a filter test, but the original target was attacked by clouds and I couldn't shoot.
I planned to Crop and Drizzle during Stacking for Close-up, but when I was separating the stars, many galaxies were captured in the east side, so I stopped trimming at the end of editing and left it as it is in Wide View. .

Main Target待ちの時間にFilterのテストも兼ねて撮影したが、本来のTargetは雲に襲撃されて撮影できず。
Close-upの予定でStacking時にCropしてDrizzleを行ったが、星の分離をしているときに東側に沢山の銀河が写っていたので、編集最後のトリミングはやめてそのままWide Viewで残してみた。
