Yep, I know the image is out of focus, but its worth telling you about how hot stars are.
Stars have colours!
Hard for our naked eye to see, but a ccd sensor can do it so much better.
You are looking at the Crux (Southern Cross) constellation, top right and part of the Centaurus constellation on the left.
Blue stars are the hottest, white/yellow stars are cooler and red/orange are the coolest. There are some our eyes just cannot detect. Our sun is small and is a white colour, if you happen to be out there looking back.
Can you see the dark patch just left and below the Southern Cross. Thats called the Coal Sack. Dense black cloud which light cannot penetrate.
The whole band of smaller stars and dust across the top of the image is the Milky Way.
The orange behind the trees is fast moving cloud lit by town lights.
I froze my butt off taking this pic, hope you enjoy.
No PS tricks here either.

I've been wanting to experiment with timed exposures that give night scenes detail and color. Intellectually I know night scenes are black and white only because my cones have fallen asleep and I'm seeing with rods. But still color night scenes are a little disorienting.
Evidently this isn't a timed exposure or the stars would be tracing circles. (I wanted to say tracing circles around Polaris but then I saw you're from Australia!). How did you get this without a timed exposure?

Polaris? now that would be a worry if I could see it from Australia
It is a timed exposure, 30 seconds worth on a tripod. At 30secs and the lens in proper focus I get little dashes of light. Focus was way off with this image, an experiment to make the light of the stars bigger or more exaggerated.
You are right, the longer the exposure the more data the sensor can detect.
To make my sensor even more sensitive to the light I put it on 800 ISO. It makes the image grainy, but it brings out the colour even more.
Night scenes with other sources of light maynot need as long an exposure. Stars are so faint.
Try some night exposures with a torch. I call them light painting. Lots of fun. I wrap coloured cloth on the torch to make it more colourful, set the camera to manual, open up the aperture and set for a timed exposure, 30 secs. Run around in front of the camera with the torches and have some fun 
Have fun!

Great photo! Oh how lovely to see the Southern Cross again, if only in picture! It's so cool that stars have colours, my husband has a good telescope and sometimes I'll go outside and just see what colours I can see

Thank you. A poor photo but it makes you realise just how colourful it really is.
Its humbling to look through a telescope and see the sheer volume of stuff out there. Happy sky watching.

i've always wanted to get shots of the stars! my camera's could never get good though :<

It is hard. You need a tripod and a long exposure. A bit of luck thrown in too.
Keep trying, you never know what you'll end up with.

Glad you enjoyed, thanks Karin. Was a bit freezing though, but fun to see.

Awesome photo Sue! I've tried astro photography too, but have never been too successful.
I have one though that I will dig up and post at some stage of the comet that was in our skies (last year?? year before??) it's name escapes me at the moment - but I was very pleased with what I managed.
The moon and stars have always fascinated me

Thanks for the great comments and fave!
Didn't really expect anyone to like it. lol
Its very hard to get good shots of the stars and moon.
Even using a tripod, its impossible to get a sharp image. Any long exposure will show them as dashes. They or we are moving so fast.
McNaught! I'm jealous, I didn't have my camera at that time, no photos

Wow, thanks Lisa.
Technically its a very poor photo, but it shows up what the eye misses. Interesting stuff up there in the sky.
It looks dark and empty, but its mind boggling how much is really out there and how far away it is.

This one is as far away from Tahiti as you could get!
The water nymphs would have their seal coats on.

Huh, fantastic pic, 
Very well timed, I'm listening to Mark's album at this very moment! Will give him feedback, I enjoy it a lot.

32 degrees, mmm ok a little hot. Perfect weather for garden gnomes.
I can see why Vincent is in Hungary, perfect weather for his nudity, it was 3 degrees this morning when I went for a swim!
Awesome camera, amateur operator!
Its really hard to focus on a pin dot of light, well impossible. It takes lots of photos to get it right, but it got too cold and cloudy to keep trying. Will freeze my butt off again another night so you can see the Southern Cross more clearly.
You like Mark's album!
I absolutely love the last 3 songs, will take me more time and listens to fully appreciate the rest of it. Love how he has played the guitar more, really good at making it sing.

Oh, so that's why I see naked garden gnomes everywhere! I need to tie Vincent's eyes next time we go for a stroll.
Whatever you say, 32 degrees is just TOO MUCH. I'd like to put a few degrees in an envelope and send it to you. You think the customs would know what it is...?
I can't wait for more space, I mean night sky photos!
👍: 0 ⏩: 1
Yes please, by all means send some degrees my way, thats if you want those space photos!
A couple of degrees in an envelope should cause as little fuss as a few leaves.
I promise more space pics
