First light through the DMK21AF04.US using the Orion LRGB filters. All I can say is, it ain't the same as the SPC900NC! Getting the color balance is trick-ee. I'm driving the camera and processing with Astro IIDC.
We're on the back side of a cold front right now--temperature's dropped 15 degrees since sunset so you can imagine what the seeing is like.
This second stack is a little better. It's noiser--I kept the shutter fast to try to "freeze" the poor seeing, and so had to boost the gain. It's a trade-off, I know, and I'm not sure which is the better way to go.
