Nice. This reminds me that I was going to add H alpha to my image from last year but so far the weather has conspired against me. In another couple weeks it will be too far west and in my Polaris tree for the rest of the year.

Your shot gives a 3D look. It somehow reminds me of an alien space ship. The dark lanes that shoot out radially toward the "front" (upper left) look like windshields (maybe the wrong term for spaceships). The core then looks like a "Federation photon torpedo" made a direct hit mid ship.

This cloudy weather is getting to me it appears.
