Yes indeed, it looks quite a bit like Canis Major.
Shouldn't we see Orion, though? Maybe we are really seeing Saiph?

Ann,
Looking at the top of the ISS track, previously-noted Alpha and Beta Leporis are to the right. To the left of the ISS track top, and a bit fainter, are Eta Lep (left) and Zeta Lep (right). They're roughly 2.5 deg apart. Saiph (Kappa Orionis) is roughly 5 deg above Eta Lep, so it's about twice the spacing between Eta and Zeta above above Eta, which puts Saiph just outside the top of the frame.
