I've been working on this since 2010. Last year was a write off weather wise so I wasn't able to add any data. So far this season I've only added 2.5 hrs of Ha on top of 3 hrs of Lum. The low altitude from Sydney makes this a
very tough target. The conditions with seeing and transparancy need to be at their best to get even a
reasonable result at 25 to 34 deg altitude!!
Anyway, still very much a work in progress and, with limited data, quite tough to process. I'm pretty happy so far though, given you can now see the faint outer extensions

I'll need 6 hours total of RGB and another couple of hours Ha before I finish.
Cheers, Marcus
PS: the 2010 Lum data and 2012 Ha data were done at slightly different rotations (10 deg or so) ... the eagled eyed may notice the result, but I'll be able to address this when I get more data.
