M17 Bi Colour

[Paul Haese]

A perennial imaging object in LRGB and HaRGB, there are not many examples of Bi Colour out there on the web. Whilst waiting to take the SII to do a complete narrow band image I thought I would put together the Ha and OIII for a bi colour image. Probably not to everyone's taste, I like this colour rendition, but maybe it is not to everyone's taste.

As it turns out I had to ditch 5 hours of data because focusor seems to have an issue on the TSA at a certain angle and has been causing elongated stars in one corner of the frame. So I had to rotated the angle a bit more and eliminated the problem (for now).

It certainly gives it a different perspective. I like it.

Yep, looks good Paul. What NB filters are you using?

Thanks JJJ

Rick this is done with my soon to be retired astronomiks which are at 12nm I think. I can never remember if they are 12 or 13nm. These are being replaced with a set of Astrodons with the Ha and SII being at 5nm and the OIII at 3nm.

Good choice, Paul. I have all 3nm Astrodons which is great for light polluted skies... except for slow focal ratios combined with targets which have a lot of NII. I'm certainly struggling on the Helix at f/9 with my 3nm Ha filter. 18 hours of data and it's still quite noisy in the dimmer areas.

With luck the new filters will get rid of your halos on some of the bright stars. Only a minor thing but I'm sure you won't miss them.

Cheers,
Rick.

Excellent image Paul and I like the bi-colour approach presented as it makes m17 stand out well from the rest of the nebula. I'll be interested to see how you rate the narrower band filters to the 12nm you are currently using.

Nicely done Paul

Nice palette. Lots of details in there.

[strongmanmike (Michael)]

Not bad Paul, some nice filaments there but you are right the colour scheme is a bit on the err?..yuk side (sorry) hey, I have produced some straaange NB combos myself ...but with the extra data you say is coming you may well change things completely

Great looking photo Paul.

Nice composition and I love the detail.

Nice clean image Paul. I don't mind that colour rendition. Although I do prefer to have some reds if I can. The delicate blues though make the image.

Interesting image... a very different perspective than regular RGB. Nice work.

Thats very Unique Paul, I dig this alot, there's always circumstances to ones capturing and this is a very interesting rendition non the less
Top show !
