Description

I collected about 15 hours total of Sulfur-II, Hydrogen-alpha, and Oxygen-III. The Sulfur-II provides a lot of structure and detail. The Oxygen-III is fainter, but provides the "blue wall" in this image. I collected another hour or so of natural color for the stars. Equipment: TEC140ED telescope, Astro-Physics Quad TCC 0.72X reducer, Chroma filters, ASI2600MM camera, CEM70 Mount, Pegasus Falcon Rotator, Pegasus Focus Cube, Pegasus Powerbox, etc. Processed in Pixinsight.
