Some issues, in particular the actual brightness, cannot be objectively
depicted, unless one considers averted vision to be part of the

the instruments could show such luminous images without averted vision
is used. As such, keep in mind that these sketches are basically
depicting what one would see using averted vision.

Enjoy.

Excellent images and a very worth while exercise. If you squint at
the monitor, you can almost be there ;-)
