I'm new to this and have tried looking for related posts before posting so dont eat me alive.

I am off to Tromso in December for a week of hopefully Northern Light watching. I really need a new camera and have been told maybe a Cannon or Nikon. Told maybe a camera I can set on manual and a wide lens (14mm) with low aperture f/2.8 ...
I read the reviews and if I am honest its like reading another language.
Having only ever had a point and shoot its way over my head.
However seeing the northern lights has always been so high on my must do list that I want a camera that does it justice should I be so lucky.
The budget is wide, can anyone please help
