Sword Of Orion Region, Better Image!


This image shows a giant star-forming region in the Orion constellation. These two nebulas, as well as a group of bright stars nearby to the left, create the "sword" of the Orion constellation, which hangs diagonally down from Orion's belt. it is located approximately 1.600 light years from Earth. M42 Great Orion Nebula on the right, Running Man Nebula on the left.

This image gets me much closer to where I want to be with this part of the sky. A lot of acquisition work and processing work here. The outer edge of the image shows a lot of warped stars - I need a field flattener. Happy with this though!

Ah, very nicely done! Great color and depth, and nicely processed Trapezium v. the fainter dust! Congrats on a fine piece!

M101 is very nice, too.
