The Hamburger Galaxy @Leo Triplet (ハンバーガー銀河@Leo Triplet)NGC3628

From here, Leo Triplet rises near the zenith of the furnishings and continues to fall west at the best point.
However, it should be the best condition, but for some reason, the Gradient is strong when shooting from near the zenith. Every time Leo Triplet fights against this Gradient.
I want a more glamor Halo.

Leo Tripletはここからは調度天頂付近に上がってきて、そのまま一番良いところを西に落ちていく。
ところが、一番良い条件のはずが、なぜかこの天頂付近からの撮影はGradientが強く出る。毎回Leo TripletはこのGradientとの戦いに終始する。もっとグラマーなHaloが欲しいな。
