Description: Bands on the blue channel. These did not show-up on the 3X drizzle. This suggests that the banding comes from the moon light on the corrector plate and not the filter, and demonstrates one more advantage of Drizzle vs. stack-and-add.

To better understand Drizzle processing see https://arxiv.org/abs/astro-ph/9808087v2 many popular textbooks have some misunderstandings about Drizzle.
