NGC2024, IC432 and IC431 in Orion - The "Flame Nebula" Region
Emission/Reflection nebula complex near Zeta Orionis
Uploaded 2/7/22

This relatively deep shot has a composition I have been trying to get right for many years! It is north up and very carefully frames the brilliant O type super giant star Zeta Orionis at lower right, the NGC2024 Flame nebula in the center, and the amazing IC432, and its attendant IC431 nebula to the upper right.

There is so much interstellar dust in this field, the primary nebula is strongly tinted a golden color, rather than the reds one would expect from this emission complex. Deep running dust lanes cut through the nebula forming a network of veins light years long bisecting this complex object. The outermost regions are tinted blue from reflection of Zeta.

To the upper right are two interesting objects. IC432 is an amazing combination of a red hydrogen cloud interspersed with gorgeous blue tendrils of reflection nebulosity. This object is one of the most unique of its type in the entire sky. To its right is a faint blue reflection nebula untainted by hydrogen called IC431.
