Corwin's Notes

===== NGC 3505 is perhaps a reobservation of NGC 3508 (which see). Even though JH's position is over 3/4 deg off in Dec, his description fits very well, including the "star 14 near." JH found it during his stay at the Cape. The large position error is bothersome, but there is nothing else within several degrees that matches the description. ----- I checked the sweep and found that JH's nebula was directly preceded by the star HD 95234 (the offsets are 3m 26s in RA and 4arcmin 50arcsec in Dec). These give a position for the nebula almost exactly that of NGC 3508, so given the matching description "pF, R, S, glbM, has * 14 v near", the identification is secure. I have still not yet been able to reproduce JH's reduction, so do not know the source of his error. Nevertheless, I'm confident that N3505 is indeed identical to N3508, so have removed the colons in the position table. Note, too, that the galaxy is also IC 2622 (which see) found by Lewis Swift.
