From Wikipedia (in the article Eugène Joseph Delporte):
- In 1930 he drew the modern boundaries between all of the constellations in the sky, along lines of right ascension and declination for the epoch B1875.0.
Well, in my (old-fashioned) star atlas Uranometria 2000.0 from Wil Tirion, I see this peculiar "shift" of Delporte's boundaries with the lines of Right Ascension and Declination, and I wonder... how would Delporte's boundary lines look like after a millennium? (when the whole system of R.A. and Decl. lines is extremely "out of tune", related to Delporte's lines which were once perfectly north-south and east-west arranged).
Perhaps it would look much more durable if he created sections of circles instead of straight lines.

And... how many stars have "escaped" their constellation, due to proper motion? (the so called runaway stars).
