Abstract (EN): In this article we present the coordinates of 67 55' x 55' patches of sky that have the rare combination of both high stellar surface density (>= 0.5 arcmin(-2) with 13 < R < 16.5 mag) and low extinction (E(B - V)<=.0.1). These fields are ideal for adaptive-optics-based follow-up of extragalactic targets. One region of sky, situated near Baade's Window, contains most of the patches we have identified. Our optimal field, centered at R.A.: 7(h)24(m)3(s), decl.: -1 degrees 27'15 '', has an additional advantage of being accessible from both hemispheres. We propose a figure of merit for quantifying real-world adaptive optics performance and use this to analyze the performance of multiconjugate adaptive optics in these fields. We also compare our results with those that would be obtained in existing deep fields. In some cases adaptive optics observations undertaken in the fields given in this article would be orders of magnitude more efficient than equivalent observations undertaken in existing deep fields.
