Helix Nebula NB - processing collaboration with Martin Pugh

hi

This has been a trying project with data gathered from multiple sites in varying conditions, but I kept at it and managed to get around 20hrs Ha and 12hrs O3.
This is a bi-colour narrowband image.

http://www.astrobin.com/full/229989/0/

I processed this as per workflow kindly provided by Martin Pugh as I really liked the way he combined the O3 with Ha.
He's been patient with my PS skills but I learnt a lot, so thanks so much Martin. really appreciate it.

its been challenging to say the least. if you want to retain O3 spikes, you lose Ha so its a compromise. I really wanted the O3 spikes more than the Ha, but didn't get it as strong as I'd have liked it.
Might add RGB stars and more O3 next year, but I think i'm happy with this for now.

Processed in Startools and PS.

SBIG STF8300
Astrodon 3nm O3 and 5nm Ha
10inchF4 CF Newt (home built)
Paramount MyT

comments welcome

Cheers
Alistair

well you definitely succeeded. That is a lovely deep image that still retains the fine O3 structure - excellent work.

you persevered and produced a very fine result indeed. It is not an easy task to reveal those O3 spikes and it is totally worthwhile sacrificing the Ha in that area in order to this.

Well done.

Martin

Alistair,

well done. I personally like the idea of something in between the Ha and OIII outright views. Your image is still very nice in my opinion despite my preference.

Martin is a great teacher and worth listening to always. I have learnt a lot from his help over the years.

Thanks Martin. Your image is what inspired this effort and as I said I enjoyed the collaboration.

Thanks Trev. I have toned the colours down slightly. I played with a few subtler versions but decided that the strong colours are warranted.

Thanks Mike. Yeah after you get some of the faint stuff you just have to keep going deeper.
