An earlier thread named Stellarium mentions the nightvision / red shield dilemma. Here's another opinion & recommendation.

Laptop displays vary, but it is almost impossible to control their brightness output enough to suit a truly dark-adapted observer. If your site is light polluted, nightvision mode done in software may be adequate, although doing so with Windows doesn't seem so to me.

A red shield really is the best solution for maintaining good dark adaptation. You can always make your own, but Ideal Astronomy in the US makes a very good one called SightSaver, and they come in different sizes. The shield is red acrylic (about 1/8 inch thick) with a clip on top that secures the shield to your display. Weather stripping around the edges seals in light and seals out moisture. They cost about $28 to $35 depending on size. I originally thought that was expensive, but it is so effective that it was worth the price.

There's also a little program called 'Dark adapted' which will 'redden' the display by varying degrees.

Thanks for that, Carlos. Looks like an excellent piece of software.

Cheers

Dark Adapted works very well on many computers, but can be a bit flaky with some graphics cards. I have found 'Niteview' to be better for me.

I also like it's feature of being able to turn off the desktop, neat.
