This is a stunning planetary nebula that proves the ESO archive is hiding quite a few treasures (not that that needed proving). Abell 24 is actually a relativelypopulartarget for astronomers in comparison to the other Abell nebulae. The nebulosity is pretty strongly visible in Hydrogen Alpha, but very faint in most other wavelengths. No oxygen! It looks like a rose.
This one presented a bit of a challenge for me to process. Initially, I tried to include older OIII data from EFOSC2, but I just couldn't make it work. I'm sure a processor much better than myself could do it though! I may try again as I learn more. I did fill the gaps of missing data with the older EFOSC2 exposures.
I apologise for my apparent laziness in writing captions (and maybe even the processing of the images).
