I'll bet that if you looked carefully, with the darker sky background in the 17mm you'll see fainter stars.

You're absolutlely right there. I should have chosen a better phrase than "losing light". But certainly, almost all galaxies looked less impressive to me in the 17mm. (It still an interesting observation though, since one EP cost me $700 and the other cost me only $160!)
