ronny, can't say this strongly enough
just shoot flats (and darks or bias)
it's an elegant solution that is likely to completely eliminate this particular problem and save processing time for finer points.
although not ideal, you could even shoot flats after the fact, just to get a feel for what it will do for your image.
do it now so you don't have too many images that you look back on and say "oh, that was before i was taking flats"

Ronny, I hope some of my private comments have been helpful. Image Processing is not an easy affair, but you have many friends here and in the larger community to help you along. Good to see you here!

Thanks Warren, really appreciate your comments which are in depth, I can't believe how challenging this hobby is. Now that I have the right gear and everything seems brilliant processing is the killer and although I bought so many programs to help it seems the end of the day flats will help but thy too are giving me headaches. Nebulous is giving me that pinnacle shape in the histogram and I can't figure out the exposure time . My colleague is using Maxim and he said it works out the exposure time. So am going to try maxim . Will keep you posted
