Veil Nebula

Here is a larger version (1344x990 pixels).

Two-color picture assembled from narrow-band Ha and OIII images using an approach inspired by Steve Cannistra's bicolor technique. Star sizes reduced by resampling the image 2x, applying aminimum filter, and downsampling it to the original resolution.
