Silver Sliver Galaxy and Abell 347

on January 10th I aimed a 250/1000 Sky-Watcher reflector with modified Canon 800D at Silver Sliver Galaxy and galaxy cluster Abell 347. I am still totally amazed by the many many tiny galaxies in this field of view. I did my best to identify each of them, but there are still some galaxies without the notation which I marked with a red X. I would like to ask you kindly if there is any way for us to identify the remaining grey smudges. I can also provide a 5500x3700 px JPEG image without notes.

Best reagrds,
