PN M 3-1
Saw this lovely little planetary nebula in the news today for its closely orbiting binary star system, and realized I hadn't processed it.
For the academically interested, an astronomical paper on that is available here:

Did things a little differently for this one. Used the c0f FITS files from MAST instead of the processed ones from the HLA. The results seem a bit cleaner. That means this image is not geometrically corrected, but the WFPC2/PC detector is such a tiny field of view that it doesn't matter much. It also means the pixel scale is different from all the HLA processed imagery, which does matter. I've noted it below.
Data from Proposal 6347 were used to create this image.
Pixel scale at full size (636x614 px) is 0.04554" per pixel
