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.
