Stellar Shot of the Week: July 23, 2021
"Abell 72 O-III RGB" - by Jerry Yesavage

Congratulations to this week's Stellar Shot selection, which goes to a one shot among a collection that was just completed by the prolific Jerry Yesavage. Jerry has been working through a number of the various deep sky catalogs, and he just recently finished imaging all of the planetary nebulae in the Abell list. You can find the rest of the works here, but they are all as impressively rendered as this version of Abell 72 (which nobody here had even seen before)! The fact that these miniscule targets are able to be resolved this well in a 130mm refractor is impressive to say the least, but the level of detail Jerry has brought out through processing is nothing short of masterful. The structures and textures in this nebula are so intricate that we were amazed this target is not more popular, and using the Oiii as the luminance was a spectacular idea. We've been told that he's nearing completion of the Sharpless catalog as well, so stay tuned here and check out Jerry's Astrobin profile at
