# The constellations in “Powers of Ten”

I watched a video called Powers of Ten made in the 70s. It starts from a view of an area in Chicago and moves the "camera" away from the ground towards the space. At 3m15s of the video, the center of the "camera" points to the Sculptor constellation area. In particular, the center is close to Alpha Sculptoris, whose declination is around -29°.

However, the latitude of Chicago is around 42°N, so the star we "see" in the opposite direction should have declination -42° (Thanks to JohnHoltz for correction). So it seems that the center should lie in the Phoenix region instead.

Did the video's author make a mistake, or am I missing something?

• The star above 42 N latitude has a declination of +42. The star underneath has a declination of -42. That's only a small difference from your calculation, so that does not explain the difference in the video. Jul 2, 2022 at 0:20
• @JohnHoltz Oh, you're right. I made a mistake. 42 is closer to 29 indeed.

• I saw the original Powers of Ten video on public TV I think back in the 1970's and also enjoyed the book. This reminds me of the slightly rant-like enthusiasm of Dr. Neil deGrasse Tyson - Titanic 3D and Cameron "Wrong Sky"
