Sketching's Finalist - IVM
A galaxy in Hydra. North up, west right. As observed on May 16 and 17, 2012 with my 16” Newtonian from a ridge on the Allegheny Plateau in Pennsylvania (altitude 2400 ft, latitude 42N). M83 was culminating over an unusually transparent horizon. I measured 21.2 mag/sq arcsec in the area of M83 (21.7 overhead). The observation time was approximately two hours. The scope-side sketch in ball-pen was a composite of views obtained at various magnifications between 75 and 225. To produce the drawing presented here, the sketch was scanned, inverted, and finished on a computer using a simulated pencil, blender, and airbrush. A Wacom Intuos 4 pressure- and tilt-sensitive pen tablet and the Corel Sketch Pad software were employed at this stage.
Good Luck to all our finalists!
