One could, and clearly people do, argue that Kant performed some measure of "good astronomy" when you consider when he postulated his ideas, and who he may have influenced and how. To claim that there can hardly be better astronomy, though, is laughable. You're saying that just about everyone who followed Kant, and did actual science (and astronomy is a science) are not performing at the same level as someone who simply made claims.

Kants claims may have ended up being demonstrated to be correct. I wouldn't hold your breath waiting for the same confirmation of your own.
