I’m testing out a night sky cam, so I can see what the weather looks like, and also capture cool stuff–like the ISS zipping by at 17,000 miles per hours–not last night that I noticed, but in this view you can see Venus rising with the moon, lower right. The moon swung into view around 2am, and brought its brightest friend. Just amazing. 

North is to the left in the video, and you can see the stars wheeling around from that point–stars on the left pivot more than they move across the sky, compared to the stars on the right. I guess what is crazy to think about is that on the equator you can see the entire sky swing by overhead with the earth’s rotation, but if you were to go to the north pole and look up, you would see all the stars in the north rotate around the sky, and they would never rotate out of view. 

Camera: ZWO ASI120MC-S (color astro camera), SharpCap image capture software. 381 x 20 second exposures, gain 42. You can see a couple hot-pixels–those are the points of color that aren’t moving. I may shoot dark calibration frames, see if I can extract those from the saved images.
