Northern Lights: An Incredible Sudoku

Today's puzzle is called Aurora and it's by the constructor shye. It's one of the most amazing sudokus we can remember. You can play it here:

Rules:
Normal sudoku rules apply. Both main diagonals (marked in blue) must also contain the digits 1 to 9 once each. Clues outside the grid give the sum of the digits along the indicated diagonal, and digits may repeat on these diagonals. Grey lines form palindromes (ie the digits thereon read the same forwards and backwards).

You can play the classic sudoku "Pure Evil" mentioned in the video by Sam Cappleman-Lynes at this link:
