These two galaxies form a close pair separated by less than 2.5 minutes.  No 
detail was seen in ngc 4298 although a mottled appearance was suspected at 288x.
Two stars were seen superimposed on this galaxy northeast of the core.  The star
closest to the core was faint and seen only in moments of better seeing.  At
low power ngc 4302 was a nondescript edge on galaxy with a slightly brighter
elongated core.  At 288x a dust lane was seen to run the length of the core.
This dust lane was not visible with direct vision but was held fairly steadily
with averted vision.  A drawing can be seen at:
