Description

The star and open cluster associated with it are about 1300 light years away. The nebulosity is a reflection nebula, and like most reflection nebulae exhibits an even bluer color (due to light scattered by the dust in the nebula) than the hot, bluish star which lights it up. (The fanciful name of the nebula is based on its flowerlike shape and bluish tint.) Modern images also show extended dark clouds surrounding the emission nebula, which are primarily observed by the infrared radiation they emit.

Description: Processing the dust is a nightmare. I let the wider view and "pull" the dust areas.
