themos,

with the amount of subs you have, the information is there. Try to reprocess this image by bringing the low levels to the foreground. That can be a much better image, as it already shows everything M51 is about.

thanks Serge, I was playing with ATrousWavelets in PixInsight but decided I needed to learn more!

If anyone wants to play with the cropped TIFF file ...https://docs.google.com/open?id=0Bws-dmFqKZThTzdFSkVKZEJRbUNiRXBuNHNIajlEUQ

Hi Themos

Just loaded your image into Gimp and did a quick levels and curves and then passed the resulting file through nosieware to remove some of the colour noise

[themos]

thanks, that's definitely smoother.

[Quatermass]

Very nice, processing often takes much more time then getting the data for your images but its all there.

[Yoddha]

There is a lot of colors and details in your image! I Like it a lot

Try the DBE tool in PI to remove the color blotch and to reduce the background.

Just thought I'd put up these two crops of subs from 2 different nights, exactly the same optics and camera and settings, to show the difference the sky conditions make (left is bad night, right is good night):

Lovely

I did try another download following your PM themos but still no joy. I'm using a Mac but that shouldn't make any difference should it?

Anyway,I've had a bash using the image posted on the forum.Tried to emphasise the red star forming areas in the arms with mixed success........... Does it looks a bit over done.......

[themos]

thanks! the galaxy itself looks very good at a certain image scale but the background, oh boy!

You are quite right,a certain image scale being,as small as possible....

This was a bit of a rush job and I really neglected the background........

I have gone over the image with dodge,burn,sharpen,and sponge tools..........Improved,hopefully.

I can't believe that this is the same image! How do you DO this?

[themos]

Just testing links to the new Gallery

[Jessun]

That worked! How do you go about to do that?

When you click in the reply window, a two line menu bar appears and one of the entries on the first line is "My Media". Clicking on that, brings up a dialog called Your Media Library. There's a column of headings on the left. Click on Gallery Images. Then select one of the thumbnails that show up.

Must try out the Gallery feature some time Interesting
