This article brought back memories of when I was playing around with astronomy simulation software like Redshift by Maris Multimedia.

I started searching for it, and as it usually goes with HN stories, I ended up on their new/modern version of it over at: https://redshiftsky.com

A brief history of their famous titles (check also aviation) is over at: http://archaic.maris.com/content/indexe5cc.html

Older versions of Redshift can be downloaded/found over at the Internet Archive:
