I'd say with 99.9% certainty that the moire pattern is just from down res-ing the images to post online. One thing to keep in mind is that the story was originally published in B&W in Warrior. Zip-a-tone was used to add definition. Part of the reason the early Eclipse issues look muddy is that the tone was poorly reproduced. Some areas too dark, others partially washed out. Either way harms the effect. I can't wait to see it done right!
