The slit is 23 microns or 3 arcsec. It normally runs in the Dec direction which is probably the best bet as the star and PSN will lie at different positions along the slit provided the seeing and guiding is good enough to split them. I could just pick up a weak spectrum of the pair with perhaps signs of a broad H alpha emission line  which would indicate a type II, though there is quit a bit of that around in the galaxy background as well. No split though (and to be honest at mag 17.9 I would not stand much of a chance of getting a useable spectrum in any case) 

Well the distance to NGC2268 is probably reasonably accurate as it based on Ia supernova 1982B (which was V mag 13.5 when discovered just past maximum) so assuming this object is say mag 17.5 at maximum this gives it an absolute magnitude of -14.8 There is then 0.2 mag extinction from our own galaxy giving abs mag v mag ~ -15 which is very much at the low end  but not unknown for supernovae eg

but if there is a lot of extinction in the host galaxy it could be higher luminosity of course.

(It could also be a foreground CV of course. We need a spectrum)

It is interesting that there has been no published professional classification yet. Maybe it is something interesting and the classification is being withheld. (Not unknown. Classifications can be submitted to TNS with an embargo)
