I'd say that was vignetting. Are you using flats? Very careful use of gradient exterminator should help you get an even better result from that data.

I do try flats but have limited success. Also I only use free processing software so no gradient exterminator (I am from Yorkshire you know!)

Just wow, nothing is impossible all right.  I just saved 200$ I think by not buying some filters.  I am stubborn enough to try and try again to shoot the Horsehead with only a simple Nikon D3200 camera.  All I have is this (so far): (see pictures).  Also a result like yours Nigel G. (Sub Dwarf) would be enough for me!  No filter you say?  There is hope!

 

Nikon D3200 (70-300mm Sigma F5/6 at 300mm) Matrix, Vivid, Direct Sunlight, Raw, about 50 lights 8 sec each, Deep Sky Stacker, Gimp, NYX tracker used. No guide, no filter.

You can easily capture it without tracking with a basic setup.

I have the same camera as you, D3200, and i shot it with my basic 18-50mm lens. I stacked 50x10s. No the prettiest compared to others in this forum but i was over the moon when i did it. The views are a different story from my 8" Dob.
