Congrats, Greg, on the candidate supernova discovery.
It can be really hard to find good-resolution reference images of far southern IC catalog galaxies.....indeed, I would go so far as to call them the least studied Bright Galaxies in the sky (some of the bright non-NGC/IC galaxies with ESO designations..... are also virtually unknown)
I have two images of IC 4901 on file, and here they are.
(IC 4901 was also imaged in the H-alpha bandpass, in the survey known as SINGG)
(The NED database (//ned.ipac.caltech.edu) also contains various images of IC 4901.)
