Description

Abell 9 is a very faint PN (barely visible in the POSS II red plate) and an exceedingly tough cookie from my sub-urban backyard. 45min of exposure in bin2x2 through an OIII filter revealed only (possibly) the very faint wisps of galactic cirrus. It was detected through the Ha filter though and even then it was a struggle to try to get some sort of decent signal out of it. To date it represents the faintest non-stellar object I have captured (yet barely).
