The Big Dipper

Dubhe and Merak. I used to know the names of all the Big Dipper stars. I’ve forgotten them. I know there’s a double-star in the handle.

I have never seen the big dipper under polaris. What latitude was the photo taken from?

Here is a photo link with the names.

Based on the assumed horizon from the picture, I’d say it’s 40-something North. At such a latitude, those constellations would be visible in that portion of the sky during the Summer and Autumn months. Specifically, starting in June during the pre-dawn hours. Each succeeding day moves the viewing four minutes earlier. And then come November, you’d see the stars in this position during the post-dusk hours. Anytime after that (Winter and Spring) the sun is above the horizon when the stars are located as such.
