Try butter and a heavy dusting of granulated sugar instead of flour.

Correct me if I'm wrong, but a 20 inch Dobsonian isn't going to show you the actual debris or modules themselves. You're right that those are way too small. What you can see are the bright, rough areas around the landing sites where the engines kicked up dust. It shows up as a tiny, bright patch. But just seeing those patches line up exactly with NASA's coordinates, that's what really hit home for me. Did you ever try looking up the coordinates yourself just to see what the online databases say?

Wait, is the bean liquid really that big of a deal? I've always drained mine and my chili turns out fine, maybe a little soupy sometimes but it tastes good. Seems like a minor thing to get hung up on.
