colourful Garnet

I assembled the LRGB files for Herschel’s Garnet Star in Cepheus, using the data gathered by BGO on 31 Oct.

Garnet star aka mu Cephei in colour

Luminance 3x20, RGB 3x10 each. Photoshop CS2.

Both B and C, the companions to mu Cep proper, look blue-white.


It's interesting reading my first recorded observation (6 Jul '08) and noting the semi-circle of white stars nearby.
