IC 2090 is lost. Swift's position is bad -- there is nothing nearby that matches his description "vF, pS, R; 3 stars in line near sp nearly point to it." There is also nothing at the positions implied by the possible digit errors that plague Swift's later positions (I've not checked at -44 deg; that would put the galaxy only 12 degrees above Swift's southern horizon; he rarely searched that far south).

Other objects that he found on the same night (5 Oct 1896) are no help. Swift's positions for IC 346 (found by Frank Muller a decade earlier) and I2008 (= I2007, found by Swift himself) average 15 seconds too small in RA and right on in Dec (though with a large scatter). There is nothing at this implied position, either.
