The one from david i indeed was able to reproduce - wuhu :)

then i tried
1) spilt color channels
2) took the red one
3) math -> subtract 50
4) make binary
5) noise -> remove outliers

i then got a picture (seen here) which only has the circle (and a little part of the inductor, which is - i guess - not to be eliminated)



and as you said i would now have to "complete" the missing parts. Has any one any suggestion how this can be done? Or does you know an macro for this?

I (as already told) did only know -> Analyze Particles -> show elipses
but this one again doesn't work here: i fitts a hole bunch of small ellipses in the image instead of one big circle.

So how could i proceed? (Because at the end i orignally wanted to find the center of this circle)
