Hi Pat. Its fun isn't it
I've attached a couple of screen dumps from Starry Night at around 10 oclock at night. The first one shows the Zenith position (small broken red circle) and you can see the relative positions of Sirius (near top of image) and Canopus. The second image looks closer to the south with a smaller FOV. You can see that the LMC is almost directly below (south) of Canopus. At a guess i would agree that it was the Tarantula Nebula you saw.
I've also include a widefield shot using a 135mm lens that may help you work out where you were looking.
Good luck
