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.
I have 32 hours Oiii on this object from the C300/16803 at SRO and 13 hours from the FSQ106/8300 combo at DSW. Must see what I can do with the combination one day.
Sure looks awesome Martin, a lot of patience waiting for 23 hours with a 17 inch and still barely enough time to get any decent data means it must be very faint.
Wow! I thought sh2-308 was dim
It must be like the MCG under lights on Friday night compared to that thing!
Nicely done- have seen a few good versions of this object on the web and yours is terrific, a real sense of delicate gaseous-ness is apparent.
I doubt I would ever attempt that with my gear even if it were visible from Australia. Hats off to you for your perseverance
I wonder is this the result of a Wolf-Rayet star like Sh2-308?

Reason: Typo
Andy - from the NASA website, it states that "Ou4 would represent a spectacular outflow driven by HR8119, a triple system of hot, massive stars seen near the center of the nebula".
