Orion - Super Wide field shot

Here's a super wide field shot of Orion taken 11 Nov.
It's taken with the Canon and 10mm lens set @ f/4.5 ISO 800

I love the colour contrast of the blue star, Sirius, and the orange, Mars.
There's also a host of other objects in this shot so I've included a sky map.

Hope you enjoy.

Cheers

That's awesome, Andrew. Thanks. If you tweak the levels, (up the input black and gamma), you can bring out a lot of structure in the Milky Way.

Thanks Steve,

Can you have a go and show me example. How do you adjust gamma in PShop?

Thanks for your suggestion dude.

I've attached the results of a quick level tweak (I turned down saturation a bit too). After resizing and jpeg-ing it does not look as good but still you can see the structure of the Milky Way.

I don't know about PS, but in the Gimp you go to "Levels" (Layers -> Colours -> Levels) and then you get a pop-up level-tweak box like in the second pic I've attached. You can pick the black level from the pic using the eyedropper and then tweak the gamma, that's the middle number, 1.00 in the pic. PS will have something very similar to this dialog.

Nice shot, you have an unusual pattern to your lens, sort of a flattened cross shape for the diffraction spikes

Nice one Andrew seems to be a bit of severe vignetting? - were you using a lens hood there mate? thats the only catch with them I guess - have you got CS or CS2? there a great devignetting feature in the digital section.

Excellent shot Andrew, I love it! That's a nice wide lens you have.

I'm hoping to do similar shots with my new 350D, my widest lens isn't very wide but i'll put it on the EQ platform and see how it goes!

Andrew, just got round to looking at the big image - excellent. That 10mm lens sure gives a nice wide field.

My widest is only 18mm I'm tempted.

Thanks guys so much.

I can't believe my computer.
I was about to reply to this thread yesterday and my Power Sup Unit packed it in.

I just managed to fix my system now, so back online.

Spot on Kearn, I was getting dew forming so I grabbed the hood.
I didn't realise the vignetting until you pointed it out.

Thanks dude.
