Binary Universe: charts of the sky

cover of the Feb 2020 Journal of the RASC
Received a notice from RASC national office that the February 2020 Journal was ready for download.

Enjoyed Jeff's fantastic image of the North American Nebula. Enjoyed Rick Staniewicz amazing parhelia image. The articles by Beckett and Percy I look forward to reading.

In my Binary Universe column I discuss Cartes du Ciel. I tested version 4.2 on my Windows 10 environment. A rich planetarium application with some planning capabilities, mount control, and features for variable and double star observers. Cartes du Ciel for Windows, Mac, and Linux is completely free.
