Σ 630 is a lovely double, HD 32273 is a 6th magnitude white with a 7th magnitude companion SAO 112341 visible 15" northeast
Gaia EDR3 data shows a mismatch in parallax (5.44mas for A and 7.11mas for B) and proper motion (-4.48/7.54mas/yr for A and -5.15/12.94mas/yr for B) indicating this is probably a line of sight double rather than a physical pair.
