Sigh.
Eric1600's use of the word "cataloged" is pretty accurate and is not the one with a "twisted perception". The Dragonfly 44 object was observed using the Dragonfly Telephoto Array towards the Coma cluster, and using observations from the Sloan Digital Sky Survey and the CFHT on Mauna Kea, it was tentatively concluded, but not confirmed, that the object was part of the cluster. Gemini and the Kecks on Mauna Kea were then used to determine the actual distance and it was only then the object was confirmed as a galaxy. That was published well over a year ago, e.g.,

The more recent six nights you mention were not used to confirm it was a galaxy or to confirm any other previous measurement, they were used to measure the velocities of stars in Dragonfly 44 to determine its mass.
