The Dragonfly Nearby Galaxies Survey. V. HST/ACS Observations of 23 Low Surface Brightness Objects in the Fields of NGC1052, NGC1084, M96, and NGC4258

Understand

We present HST/ACS imaging of twenty-three very low surface brightness ($\mu_{e,V}$=25-27.5) galaxies detected in the fields of four nearby galaxy groups.

• These objects were selected from deep optical imaging obtained with the Dragonfly Telephoto Array.
• Seven are new discoveries, while most of the others had been identified previously in visual surveys of deep photographic plates and more recent surveys.
• Few have previously been studied in detail.
