Loads of faint detail there Peter! Very nice image.
A change in the weather would be well received. Its looking good so far today but showers are forecast for the rest of the week.
Thanks...I've always had this theory: if it's a new moon it must be raining

The 8300/AO is a good match for the Honders.

Ta Greg. While the RHA works well with the 8300, but I think I get better resolution with the RC and 16803. That said, neither like average seeing much...more so with the RHA.
It is indeed the longest exposure I've made to date. Not a lot of faint galaxies however, as it's only deep in h-alpha (at present )

The neb extension is insane for urban imaging, shows what can be done with megadata in urban skies .
Thanks Fred. I did a fair bit of research on other Helix images prior to posting.
While some of the very faint outer elements have been hinted at, its true structure has often been invisible or distorted by processing artifacts.
As it turned out some so-called "deep" examples were just processed noise, rather than real structure.... hence I'm pretty confident to have brought something new to the table.
Thanks H.... I started with 20 minute subs but quickly realised 30 minutes was the way to go. In fact I'd go deeper again, but I suspect there is a plot by Sydney ATC to constantly vector aircraft above my obs
It's revenge for every time you have asked for a track diversion
I gave them your lat/long just to help out. They were very grateful
Bloody hell, a cracker.
Peter, I know you are a man of few words.
But that is a marvellous image and if it really is a modest one, then I would be looking forward with tremulous eyes (if this were possible) to your un modest ones.
Astonishing really..

Like this one a lot Peter. A bit more RGB will do the trick I reckon. Those outer extents are hard aren't they. I had to push and smooth my version very hard to show them. I must revisit it one day.

Thanks Marcus, extra data is always a good thing

Thank you Graham, most kind. I suppose I could have given it a more snazzy title
How about: "Mote in fiery God's Eye!! " (now that's bound to improve the ratings )
I've recently uploaded a deep negative version of just the h-alpha data.
(same URL as the original post)
With some very kind help from none other than Fred Watson and one D. Malin, it was very rewarding to discover some deeper features and revealed in my humble effort that were only hinted at in the AAO red plate data from a generation ago!
Well you did a pretty good blending job there Peter - it's a nice looking Helix. That 34 hour Ha is pretty amazing - there are structures there I didn't know about.
