Ooey-Gooey was a decon worm, with glistening beads that you could see ...

Two things came together to cause me to reprocess this. The first was the magnificent recent post by TopHeart, which made our previous processing look positively blurry. The second was having just taught GoodLook 64 how to deconvolve a starless image.

Here is the Musca Spiral Planetary (about 3.5 min arc tall) after 10 rounds of Richardson-Lucy deconvolution. (Both to avoid magenta halos and to avoid issues with panda eyes around bright stars, stars were removed prior to decon, then replaced using just the H-alpha channel mapped to white).

We were rather delighted to find that the OIII in the nebula, previously a blue blur, resolved itself into a series of six or so parallel interlocking spirals, with largely black in between. The pattern of lumps along these fine blue threads matches the largest and most obvious lumps in the far far sharper Hubble shot, so we think they're more or less real rather than glistening beaded decon worms.

... All along the railway track, his gizzards were a-splatter, but they didn't waste a bit of him, for now he's peanut butter.
