I don't know if it's noticeable, but I can make it out slightly on my CRT.

It's a lovely image, one to be proud of.
Yeah that gradient is a real hassle. If memory serves me well, then I did this image when the last quarter Moon was rising (last month) - which MIGHT account for gradient. But to be honest I find gradients prevalent in most of my images - I believe this may be my primative way of making flat fields.

So I am getting a Flatmaster CCD LightBox ( see http://www.astrohandy.com/flatmaster/index.html ) which I hope will fix my gradients.

Actually Mike Sidonio finds it quite amusing the way I take flats.
