We present a second set of results from a wide-field photometric survey ofthe environs of Milky Way globular clusters. The clusters studied are NGC 1261,NGC 1851 and NGC 5824: all have data from DECam on the Blanco 4m telescope. NGC5824 also has data from the Magellan Clay telescope with MegaCam. We confirmthe existence of a large diffuse stellar envelope surrounding NGC 1851 of sizeat least 240 pc in radius. The radial density profile of the envelope follows apower-law decline with index $\gamma = -1.5 \pm 0.2$ and the projected shape isslightly elliptical. For NGC 5824 there is no strong detection of a diffusestellar envelope, but we find the cluster is remarkably extended and is similarin size (at least 230 pc in radius) to the envelope of NGC 1851. A stellarenvelope is also revealed around NGC 1261. However, it is notably smaller insize with radius $\sim$105 pc. The radial density profile of the envelope isalso much steeper with $\gamma = -3.8 \pm 0.2$. We discuss the possible natureof the diffuse stellar envelopes, but are unable to draw definitive conclusionsbased on the current data. NGC 1851, and potentially NGC 5824, could bestripped dwarf galaxy nuclei, akin to the cases of $\omega$ Cen, M54 and M2. Onthe other hand, the different characteristics of the NGC 1261 envelope suggestthat it may be the product of dynamical evolution of the cluster.
