A target of opportunity only ~25° up. Turns out this cluster is bigger than the FOV, so this is just the core. The high-rez version is at ~.53"/pixel. I was pleased with the color combination this time. Details are here:

The image is lovely Charlie. At first I was puzzled by the comment that M22 was bigger than your FOV. Then I saw you were imaging with a 16" (albeit with the 0.63 reducer). The high-rez version is impressive.
