Description

This is a two panel mosaic. I am new to mosaic-ing thing, so of course I chose to do it backward. Not the least of which was to begin investigating how to do a mosaic after I processed each image.

So there are a number of artifacts.

In addition, I processed the bottom panel to help preserve the M87 jet visually, even though it ended up being so small that it was pointless. However, to get the image into the mosaic and then dumb it down so that I could upload it, the jet ends up looking like a thumb sticking out of a fist. Really there is little detail at that scale with a wide field scope anyway. Lesson learned. I may revisit the data as I learn more with PI.
