I am quite excited about how this image turned out.

It is 7 filters worth - Luminance, red, green, blue, Ha, O111 and S11.

I took this over nearly a year. TEC180 flourite and Tak NJP mount and used a FLI Proline 16803 with Astrodon Gen 11 filters.

This area has always been a stunning area with lots of colour. I am happy to provide a muted narrowband enhancement to an LRGB image.
It has been processed so the stars were unaffected by the narrowband images.

It seems to have just about every colour in it somewhere. Normally I wouldn't like green showing but I feel it adds something here. It certainly shows the different emissions going on in this area.

This is my favorite image for the last year and one I am most happy with.

9 hours and 45 minutes:

Greg,
That's a sublime image and I'm impressed with the processing as well as the time dedicated to the image. Everything works in it for me.

Greg, the time you spent on this has certainly payed off, the results are pretty much what one would expect from so much effort and dedication, well done indeed.

It's a nicely crafted image for sure but I have to admit the green doesn't quite work for me. I prefer the natural looking version elsewhere on your web site. Of course this is all a matter of opinion.

Cheers

Hi Greg,

Another amazing photo....wow!

I really look forward to your photos. The colours, composition and subjects are so appealing and you always seem to be presenting something new or different.

To new astrophotographers like me, you are inspiring.


Thank you.


Ross.

Thanks Allan. I was happy with the result and I was pleased to be able to present a narrowband image in a less full on way.



Thanks Leon. Its an interesting combination of filters. Each brings its own contribution.



Hehe. I know what you mean Steve. Green is not normally welcome in an astrophoto for sure. If you got green stars you'd be horrified. Normally I don't like green at all in any astro image. However in this one I liked it because it just balanced out all the range of colours. It made it more colourful plus highlighted an area that made it different. I totally get its a personal thing and not everyone will like that aspect of it. Its funny how green is the one colour that is not on in astroimaging.



Wow, thanks Ross. I am glad to create that effect.

Cheers Greg.

Great idea Greg. It all seems to work as far as I am concerned. I like all the colours presented. Certainly something for me to think about too. I did this object last year and would like to add some narrow band to it also. The OIII has a nice effect of adding depth to the image.

There does seem however some star elongation on the left hand side of the image. Mainly the blue stars, but not too distracting.

That said if I was judging this image in a contest with other images of the same target I would probably award this image with first place. Very nice work.

This image is a bit of an enigma for me..when I first openned it I'll be honest I thoughteeek :scared: you gotta be kidding :lol:... but so as not to make a rushed decision and judge an image in a few seconds (like I know many do arhem tut tut :rolleyes:) I had a good look, shrunk it down, enlarged it stood back from it etc I even left it alone and came back to it and looked at it again on different screens at home and then today at work (which is a more contrasty screen) all the while trying to remain objective. After all this I have to say while I still don't exactly love it, I am starting to warm to it a little, it's certainly an interesting alternative view.

I still like the normal LRGB type appearence better on this area but overall though some effort went in to compiling it I know.. so good on you for trying something different..of course what would my eyes know anyway...David Malin :whistle: may well just love it ;) :lol: :thumbsup:

whoa, thats certainly different, I like the extra colour the NB gave.

The NB star fringing is a bit busy and distracting with so many stars, perhaps Ha and rgb mix only stars would look cleaner?

All in all though, an excellent rendition of an overdone area in a totally different fashion.

Sorry for the slow response, been away imaging at my dark site.



Thanks Paul.

I'll check out the star elongation. Perhaps a bit of flex from the setup. Its quite heavy.




Thanks Marc.



Yes narrowband choices are not everyone's cup of tea. Your recent Eta was like that for me but I loved the HaRGB version. Having said that there does seem to be common ground for agreement in narrowband colours that most seem to like and that is the blue, browny, red type pallette.




Thanks Fred. Doing an unusual mix of narrowband isn't going to win a competition but I liked the unusual view it brought to the table.

Now this is something different Greg. It adds something to a lovely section of sky. The detail in the NB shows through and the variation in colours seems to show off different bits of the image very well.
You have to be happy with this image but it does look and sound like a very time consuming imaging method.
Great stuff Greg.

Thanks Doug.

Its taken over 2 years, each one was its own separate image so its a matter of adding the new data to last years image. Thats the value of keeping a database of earlier images. Although some of my data is hard ot get at due to hard disk failures.

Thanks JJ. Its an unusual view. I liked the clarity the scope and camera managed to achieve there.
