IC 1150
IC 1150
History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
IC 1150 may be a reobservation of NGC 6018. As Malcolm notes, the description -- including the superposed star -- and the declination are good matches to Javelle's single observation in July of 1891. However, Javelle's RA is off by 48.7 seconds of time, an unusual error to make.
I searched the field for a star-galaxy pair with his observed separation (-20.90 seconds, -8.4 arcsec in north polar distance), but found none. Nor is there such a pair at -16 degrees, -6 degrees, +6 degrees, or +26 degrees as there would be if he made a digit error in his comparison star name (it is BD +16 2854). The only other galaxy Javelle found on the same night (IC 1155) is just where he observed it, so we are left with a mystery.
Whatever happened, I've included the identity with a question mark on the IC number. I'm obviously not completely satisfied with the identification, but certainly think it is possible.
