This set of fifteen lunar eclipse images on Nov 19, 2021 have been HDR (High Dynamic Range)-composed of several shots exposed with different EVs to represent wide differences of brightness. Our naked eyes can clearly recognize both lunar surface features in shadow and un-eclipsed parts same as these images. Unfortunately this eclipse was affected by thin clouds, it made the images with muddy color. However, images taken during from 18:07 until 18:24, which have comparatively good transparency conditions, can be detected that the shadow near the edge of Umbra has a bit bluished color, so-called the "Turquoise fringe". It's considered that the impressive color is due to the passed and refracted sunlight through the ozone layer in the Earth atomosphere.
  All images are displayed turning the celestial north direction upward.
