That is a stunning image Eddie! This proves to me that narrowband imaging can be used to show up detail not previously seen. I wouldnt even pick that that was the swan due to the amount of excellent detail in the surrounding nebula. The star field is very sharp too. Looks like everyhting is working for you there!

Great detail in the image but the colours are a little different to what I am used to.

Nice pic! :eyepop: The extent of the nebulosity is huge. Never seen it quite like this before. Pretty cool. Loads of details. I like smoother processing, a bit harsh to my taste but that's me. Top work. :thumbsup::thumbsup:

Thank you all for your kind comments, I was also supprise to see all the extra nebulosity during processing.

Gee, that fair jumps out at you, nice detail. Thats a strange colour balance even for the hubble pallete, and its over processed to hell :P, but overall striking, lets call it artistic :D.

Since youve done a lot of work so far, perhaps you could take some more Ha exposure and make an Ha;Sii;Ha;OIII. That would fix the noisy background too.

Very nice Eddie. Now that is a lot of exposure. Looks a little sharp and crispy for my liking but the amount of detail is wonderful.

Well done and I admire your patience.

Eddie,

That is one enormous photon collecting binge you went on.

I have to agree with Fred in that it does look a bit over-processed, but, I'm still drawn to the fascinating object which is the centrepiece in this composition. Well done.

P.S. I grew up in Toongabbie. :)

Regards,
Humayun

The Parramatta light pollution is what I'm up against here in Toongabbie.

I was a little quick to get the image out so here's the reprocessed version.
