Peripheral vision (or averted vision as it's usually called) is useful to master in astronomy, often used when looking at feint defuse objects like galaxies through a telescope. As you say, the rods at in peripheral part of the eye are better suited to low light. I'm not sure how well this might work with pointed sources of light like stars though.
