Description

This is the same image I published recently  htps://www.astrobin.com/bllq80. But for this one I processed to bring back the OIII (blue) which was absent from the  former image but revealed in the luminance of green and blue. The OIII is very faint on this image but was there. Narrowband imaging offer such liberty to make out elements such as Ha, OIII and SII.
