Beautiful as always. Any reason you used two different cameras?

Here is an image i have been working on for about the last 4 months. Its of the western part of the Veil nebula often called the Witch's Broom nebula. This was quite a challenge seaming it all together as the bright 4.2 magnitude star fell very close to the edge of the frames. But all and all turned out great. So much to look at. Now to do the entire region...
