A good comet image processing (composite) tutorial?

Recommended Posts

Hi All

Does anyone know of a good tutorial for processing 2 stacked images of a comet (one stacked on stars, the other stacked on the comet's nucleus)? I know DSS has a feature but is there a better method in Photoshop?

I've got two nice images of comet 41p / M97 / M108 last night and not sure where to start with getting a composite so the background stars aren't streaked.

Any help greatly appreciated.

Enjoy the clear skies!

What image processing software do you have available to use?

There is a thread on comet lovejoy where the member outlined how they did their composite image.

Something along the lines of extracting the stars from one and removing from the comet then adding the extracted stars. So I guess it will be as easy as the mask tool is competent. Don't forget GIMP you could try that too.
