    Hi,
    Does anybody use this? I'm a beginner and I thought it would be useful to get.

    I know stellarium is good and I have it installed here but it would be a little painful having to bring it out although I could.

    Is it really that important to have your eyes adjusted to the darkness?

    My understanding was that a map and an infrared light for the correct tools for the job.

    Any opinions appreciated - thanks.

    A decent atlas is very useful. I have the small, ring-bound sky and telescope one and find it very useful, though bigger pages might be easier to use but no complaints.
    Dark adjustment is more important than anything else and a laptop screen spoils it, taking 10 to 20 minutes to recover.
    You can't see infra-red radiation, you need a red light. You just need a low output red LED, a CR2032/CR2016 or similar battery and a 120-odd Ohm resistor to make a handy "torch". Or you could put red film (sweet wrapper?) over a small torch but it might be too bright. Think of the amount of illumination a half moon gives to the ground (not looking straight at it) and you're in the right bracket.
