Moon at 3600mm (that's a full frame, not a crop..)

While freezing my butt at night today, I discovered that with the method that I'm using to take these images, there is a spectral focus misalignment. That is, the red/green/blue channels aren't on the same focal plane. Therefore, you cannot get perfect focus, since one of the channels will always be blurred. I can probably fix it. Until then, this is the moon in the blue channel.
