Sketches
All the sketches except Comet Hale-Bopp were made using
18" F4.5 Dobsonian telescope. I drew the objects in a pencil on white paper and
input them to PC by a scanner. Then, white and black were reversed
electronically. North is up if the direction is not shown.
In some sketches
not all the visible stars are drawn.
