Make your own RGB of my Rho/Antares shot

Guys - Here are the three colours of the Rho/Antares I posted a few days ago.

Have a go at putting together an RGB composite of the shot. Play with the colours, levels and contrast. See what you can come up with.

I wont be upset if someone can come up with a better version of the shot than mine, I am only just getted started in the caper.

Have fun.

All files are about 550k.

Hi Monte

Nah, on second thoughts, your processing is much better

For some reason I can't download these tiff files.
Any chance you can upload all three into a zip file somewhere (even here on the IIS server) Monte.
I'd love to have a go !

Hi Andrew

I found the same thing just clicking on them. Right click and save target as, that works.

Hi Monte, I have no idea at what I am doing...but this is what I ended up with... It`s more involved than doing my canon shots!!
cheers Gary

Fred - why is your image size bigger than the orginal? Keep it at the normal size and you should have a better result. As it is you have done well on the colours.

As for the rest of you - well done!

I doubled the size as soon as I downloaded it, its a nervous automatic reaction us pixel-challenged plebs (mine cam is 1.5MP) have to subs in a vain attempt to increase res. Processing larger tends to unpixalate images. You wouldnt know about this, you wouldnt need to even come close to that sort mucking around hehe.

I found the res on your subs you posted a bit small to get really fancy, so I gave up ;-(.

Sheesh, the colour is very mute, I cheated to get it up, no wonder you over-curved to push up the colour that was there.

I think its a difficult pic to process to do it justice generally.

You've captured very nice data Monte.
This has lost a bit of colour depth when compressed for the web but I could only imagine what it would be like processing with the full res frames.

Hi Monte, thanks for the opportunity to have a play with your data. I had a quick play in Maxim and came up with this. hope I've done it justice.

Cheers

It's amazing to to see all the variations that members are coming up with. there are a lot of varied interpretations and they all look great.

Cheers

This is an interesting thread! Very interesting to see such different results from the same data! Obviously lots of scope for creativity.

Looks like everyone is enjoying this. Perhaps this could be a regular - someone posts raw data and all you data tweakers give it your best shot - then we vote? Could be a lot of learning as people describe the techniques they use??

Great idea, I for one will have a fairly constant flow of RGB's but there will be others.

Here is my go at it Monte. I used EasyHDR to compress the dynamic range.

Fascinating idea! Never processed an astro image before so had fun. Only have Photoshop so had to work out what to do with the layers.

It's amazing how different everyone's results are - I've made a composite of those done so far - it's only a posting-size image but can make higher res available if someone tells me how to do it.

My mediocre result is the one on the top right - I tried to increase saturation but started losing image data. Obviously dedicated astro s/ware is the way to go.

Guys ! Can someone please grab my original image and include it in the mosaic? I don't have image processing software on this computer.
