The name of a particular low extinction region There is a region called Baade's window.

I remember there is a similar region called "somebody's window", which also has a low amount of dust.

Does anyone know the name?
The Lockman hole?

http://en.wikipedia.org/wiki/Lockman_Hole

It has a column density of neutral hydrogen of $6\times10^{19}$ cm$^{-2}$, which will correspond to very little dust.

Two others I've heard of towards the Galactic bulge are known as the Sgr I and Sgr II windows.

Finally, I offer "Stanek's window" towards the bulge, which has been referred to in a number of the Chandra Galactic plane X-ray surveys but appears to have no refereed publication associated with its discovery. I found this on arXiv.  http://arxiv.org/abs/astro-ph/9802307  It is at $l=0.25$, $b=-2.15$ and has $E(B-V) \sim 0.6$.
