I imaged galaxies around the stars of the Pleiades cluster M45 with my refractor and published it in Amateur Astronomy magazine challenging anyone to identify some of these tiny galaxies. No one did. The attached chart from Sky Tools shows many faint galaxies around M45 but none right within it. I suspect this is because the Pleiades cloud obscures the brighter galaxies. The larger attached image shows galaxies through the Merope Nebula (NGC1435)! Would you believe there is also a 18.3 magn. asteroid in this larger Merope image?!
There is also a tiny nebula adjacent to the bright star Merope! This is IC349 made famous by the Hubble Space Telescope. I attached a close-up of IC349 I took with the HST image superimposed for comparison. Notice the beautiful orange star nuzzling up against one diffraction spike and the faint anonymous galaxy (lower right) shining through the Merope Nebula.
