Star Dome

My attempt at a realistic star projection dome.
Includes the 500 brightest stars, in their correct positions, and with relative sizes according to their relative apparent magnitudes.

The sizes of the holes are in steps, according to the rounded up value of their magnitudes, and negative values are substituted with tiny positive values (e.g. Arcturus). The next version should have gradually increasing holes instead (once I get my head around logarithms.
