Description: Object difficult to impossible to find
with this instrument under these conditions. Possible
identification of galaxy center made, but the companion
galaxy "smudge" was not visible (which made a definite
confirmation impossible.) Worth a try in darker skies,
perhaps. (Certainly visible from this site in 12.5".)
