Opening the gateway question

I am starting to work with KOF and I was wondering, how essential is it for the gate to be drawn entirely by the light of the stars and moon? As I am getting not very bright nights and finding it difficult to draw in precisely.

Is the working ruined if I used a torch?

I have only done a little travel through the KoF squares but when doing so I didn’t use the method described in the book.

I opened the square until the square itself fell into the background and an image/vision of the destination appeared within it and then projected into that vision.

When the square is fully open its like looking through a window, pretty cool effect.
