Nice job. The benefit of ganging together those cameras really shows when you compare the field of view to my own attempt a few weeks ago. A cropped version originally appeared in this thread
but here's the full monty, downsized by a factor of four, with just a 12 pixel wide black border, to allow a direct field of view comparison:
5 x 200 second subs in each of red, green and blue (50 minutes of data) using my TEC 140 plus FLI ML16803 camera so telescope time was comparable but your array has allowed you to go wider. Congratulations on finally getting it up and running. And yes, isn't it nice to sit in the warm and watch those subs appear on the computer monitor!
