G'Day Trevor. Nice try, but there is an overabundance of blue. If you use the average star in your field as a reference, try to keep these white, and the rest of the colours will mostly follow. Stars aren't meant to be aqua.

Thanks Chris for that seems to be more blue when stacking in DSS

Any ideas

Cheers

Do you have Photoshop?

Image/Adjustments/Colour Balance menu will sort most of the blue out. For both highlights and midtones, slide the blue towards yellow and the cyan towards red just to try. Have a play with levels too. :thumbsup:

A reasonable image Trevor. Sort out the bright blue but don't expect the red colours you will see in my images or those of others using a CCD or modded camera as the filter in front of your CCD is blocking the Ha and is quite sensitive to OIII hence the blueish tones around the nebula.
Tone the blue back and it will be quite a nice image.
If you have Photoshop have a look at this website. It is full of useful info including masking the cores of items such as Tarantula and Orion.

Keep at it.

Trevor,

I agree with above posts.

The technique is called colour balancing.
In photoshop if you can, make sure you see all 3 colours in the histogram. You should see three peaks, 1 for each colour.

Then as Omaroo suggested, adjust the sliders until all 3 peaks are in line with one another, and then you are done.

Cheers
