Perhaps this is only subtle as I have not changed any placement of stars- Only pairing up of new and old photo images of the same pastel. This is one of the Andromeda Galaxy I made about a year ago as more an impression of what I believe to be a good example of what can be seen through the eyepiece in a 10 inch Newtonain from dark skies as opposed to what photographs show. [New Photo of old 19" X 25" pastel above.]
And the paring, next window following > New image on left- old image on right

Compare new and old photos of same sketch [19" X 25"] - New on left - old on right - A 3~D image may be viewed if desired.

Hi Mark - respect to this scetch and the 3D impression.
Some other thoughts:
All the 3D sketching must be orientated by reality. 3D arrangement by planets and moons are showing results we can face eye by eye from our experience. More difficult are 3D structures form open star clusters. Necessary to get the information about the distance of the individual stars. Complex is also the view to galaxies. The spiral structure und the bulge is easy to define. But what is the exact 3D position in space for M31, M32 and M110? Sometimes it is very hard to decide the rule to be offside in soccer viewing sports on tv.
