For those interested in an artificial horizon I recommend a mirror mounted on a photographic tripod ( pan head ).
To level use either a bubble leve as from a trisquare or better observe a plum bob string and its reflection in the mirror from 2 directions, perpendicular.
A continuous strig means its level in that direction.
