I was just about to point that out, in my defense.

Big Bear, Big Dipper...
Every now and then one of the images I post will have an asterism, which is just a pattern in the stars that is interesting to see, but the stars have no relation to each other unlike stars in constellations. There is a famous one where both happen at the same time, the stars are in an asterism and in a constellation...
This is a screen capture from Stellarium, with annotated star names added on top. All of the stars are part of constellation Ursa Major. The blue-ish colored lines and the white-ish colored lines connect the main constellation stars, the white-ish colored lines alone form asterisms. The orange-ish colored labels are for the stars in the two asterisms.
This is the equivalent of an 80 seconds exposure.
As a side note: Alcor and Mizar are a famous double star pair, very easy to see visually or with binoculars or telescopes.

"Will you walk into my parlour?" said the Spider to the Fly” *
Back on page one of this thread, there is a post showing a quick exposure isolating IC 405, The Flaming Star Nebula. That section of the sky has so many things to see it is almost a tourist-oriented nature-viewing area.
Some of the highlights include tadpoles, starfish, spiders, flies, pinwheels and more.
This is the equivalent of just about 56 minutes of exposure.

Will the spider once again coax the fly into its parlour? Will the fly escape the machinations? Their exchange is in the sky for us to ponder...
