Hi did another try with the stretching, I managed to get 3 moons but the back ground went blue and I noticed your image is still black on the back ground. What method and program did you use to stretch? I tried in Registax and got no moons and the result of 3 moons was once the image was saved and then loaded into Photoshop, but it did turn blue.
I dont want to be a pain but if you could spare some more of your knowledge it would be greatly appreciated.
Thanks
Carl

Thanks Carl. If you stretch the levels on the image after stacking, you should see any moons captured. It's a matter of then saving that stretched image, along with a normal image & copying & pasting the moons from the stretched image onto the normal into the corresponding positions. I use Paint.net for this as it memorises the positions automatically within 1 pixel. I then apply a Gaussian blur to the moons.
Attached is a copy of my stretched image for this data set.
