The Last Saguaro Flower of Summer

This flower opened on our big saguaro cactus out front this morning. Most of the flowers had come and gone in June, but last week we noticed a new flower bud. When I say last of the summer, I mean for this cactus, as there are others in town that will likely have more flowers to come. Maybe even this one will have more, but I doubt it.

Since the cactus is very tall, in order to see inside the flower, I had to take this shot from across the driveway with the telephoto lens. Canon SL1 settings: F8.0, ISO 100, Shutter 1/500 sec., Focal Length 300mm.
