They are both pretty bad, but it probably has a lot to do with the Toucam dying a terrible death. Both images are cropped from very badly affected Amp Glow images.
The image capture settings were turned waaayyyy up to get anything at all. It has become almost impossible to image with it.
I just wanted to try a comparison of Stacking results. Bit hard when the detail is screwy.
The stars on the deepsky stacker image are very blocks and look like they have been over processed in some way. Have they been summed or averaged when stacked?

These are different ways to add images together. The process used is to align the individual frames creating new aligned images and then each frame needs to be added together. This can be as a simple summing of the data or the data can be averaged. There are lots of other methods as well.
Some of the methods are summarised in http://www.astrosurf.com/buil/iris/t.../doc121_us.htm
This is specific to Iris but the principle is the same.
I haven't loooked at "deep sky stacker" but registax uses an averaging process of some type rather than summing the data.
The object I've put a square around in your Deep Sky Stacker image appears to be missing from your Registax image. What could it be ? It isn't because of the slight difference in cropping.

That's interesting, Mark. Dunno why it vanished. I notice by jumping from one image to the other that many of the stars in the Registax version are dimmer, but that one should still be visible, and it's not

Mine is is english or try here
Use the link on the above page to the tutorials on stacking.
Curiusly when I link from my post it is in english but when I link from the quited link in your post it is in French and a different page.
I have just downloaded Iris, and couldn't work out how to do the Gradient removal. I gave it a go and it put crosses all over the image and then it wouldn't go any further.
I then read the tutorial and it says I have to type commands in like we used to with an old Commodore 64!!!!
I think I'll give it all a miss before I chuck this pooter thru the window.

I am not into command line stuff either but I have found iris to be pretty simple. It has a little command line box that is easy to use.
