A little off topic, but I asking for suggestions for simple planetarium software that I can load or purchase for showing the night sky.
The reason is a planned trip in mid February to Finland at 67 degrees north where I hope to see the aurora or at least a starry sky, clouds permitting. The target computer is a MacBook Air or an iPad. I look forward to many suggestions!, Regards, Doug --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
