 Need fractal help

Hi, I just wanted to drag some more attention to this post I made in the Science and Tech forum, since I haven't had a reply there yet.
"...is someone able to recreate the fractal shape in the image below and upload a large to huge-sized copy of it? The coordinates are somewhat included in the original filename: phi-2, 0
The purpose is for a photoshop job, but the image is too low res to get a clean cut out of the shape."
I saw this data concerning this specific julia set on this webpage:
Filled Julia set for fc, c=1−φ where φ is the golden ratio.

That's similar, but the specific fractal shape I need is this one, and it needs to be very high res with unblurry edges so I can make a perfect cutout of it:

I have looked for easy fractal generators and have found none. I have also tried making them on maple, and even on excel using iterations. No luck though.
Oh yea, good luck making a perfect cutout of a fractal, because thats technically impossible. (i know what you mean though  )
EDIT - Also, you are sure that is the julia set? It looks more like the mandelbrot set that coaster posted. I think it would be hard to generate that specific one without knowing the more specific parameters used to make it. That recursive relationship you posted in the begging wouldnt make that picture (I think).
--------------------
Behold yon miserable creature. That Point is a Being like ourselves, but confined to the non-dimensional Gulf. He is himself his own World, his own Universe; of any other than himself he can form no conception; he knows not Length, nor Breadth, nor Height, for he has had no experience of them; he has no cognizance even of the number Two; nor has he a thought of Plurality; for he is himself his One and All, being really Nothing. Yet mark his perfect self-contentment, and hence learn his lesson, that to be self-contented is to be vile and ignorant, and that to aspire is better than to be blindly and impotently happy.

Any vague request for colours ? I can't get them right, and I'm not really into tweaking palettes, but there's a fair share of colour presets in the program so I can check a few ones. Also, this on is 2000x2000, do you need it bigger ? Tiff ?
anyway, there you go

You might also want to have a look to a post I made in the art section about free fractal generating softwares and so you can tweak your own. It wasn't really hard, just select the julia set and select the julia origin's real part to be -0.618 and imaginary part to 0.0 . I used FractalWorks but this is only for OS X.

Thanks deimya! I'd love a bigger one if that's not too much to ask, perhaps double that size? The colour palette is good because the black next to white makes it really easy to cut out without photoshop confusing where the exact border is.
I've tried playing around with Ultra Fractal 4.04, but it's still pretty confusing to me. I was trying to recreate this image in the prog with no luck, but I'll try the values you mentioned and see if I can make it right.

It does look like the mandelbrot, I just identified it as juliet because of the filename and it being listed on the wiki page for juliet set.

My pleasure, there you go, 5000x5000. Something else ? Bigger ? Tiff ? And yeah, it's a Julia Set

Sure, I'll go for a tiff as well. I tried the value in UF and got the set, I just can't export it myself without having logos covering the picture because I'm using the evaluation version.
How did you know or figure out the correct value?

You included the information in your first post, and it's also on the page you refered to, that it's a julia set with c = 1-phi, and phi is the golden ration, which is about 1.618, so I used the julia origin c = -0.618.
Here's the tiff
