When and where to look for Microscopium

Microscopium crosses the meridian — its highest point in the sky — at local midnight around August, which makes the months from July to September the easiest time to find it in the evening. It spans declinations -44.0° to -32.2°, so visible from everywhere south of about 46°N.

The quickest way to find it is to open the live AR sky map and point your phone at the sky — if Microscopium is above your horizon right now, its figure is drawn in the position it genuinely occupies above you.

Spectral class is a temperature ordering, running from O at around 30,000 K down to M below 3,500 K. A constellation is a direction, not a group, so this is simply what happens to lie along that line of sight.

The closest catalogued star in this direction is HD 201647 at 103.3 light years. The most distant is HD 196829 at roughly 1,144 light years — stars that appear side by side here are nothing of the sort.
