Good morning
When I first got data on this fabulous nebula about 18 months or so ago, the 'squid' was just ridiculously faint. Twenty three hours of OIII barely brought it out, so when I first processed it I actually got permission to incorporate the IAC image, and fired it off to APOD in the hope that the wider field data combined with the IAC data would get it noticed. Alas, no cigar.
So, using my own data I have combined a few techniques together in order to show the squid without it being drowned by the Ha. The two exposures are literally poles apart. There is no evidence of the squid in the Ha data whatsoever, but it shows a mass of hydrogen as you would expect.

Ha: 7 hours OIII: 23 hours. CDK 17 and SBIG STXL11002.
cheers
