Orion Sword
I have photographed the Sword of Orion many times and every image is different. Sky conditions and processing both play a role. This one has much more striking color than my previous ones probably due mainly to the very clear sky.
Details
Modified Canon T3i on Orion 80mm refractor with Astrotrac mount.
56.2 min of exposure all at 4 min per frame except for one 16s frame to capture the bright core. ISO ranged from 200 to 800.
