Lodestar-C star colour + Uranus

[nytecam]

A little experiment, via the OSC Lodestar last night under moonlight, on a few bright stars heavily defocused onto the sensor to sample their colour - they're arranged according to their spectral type BAFGKM from hot to cool which they match quite well for colour.  The exposures very brief eg ~ 1/10sec which also captures the unwanted atmospheric turbulence.  

Also included is Uranus [in a longer exposure that smooth out turbulence] which seems greenish but is not 'stellar hot' [quite the reverse] due to atmospheric methane absorption of reflective sunlight !

That's very impressive. Thanks for sharing.

A fascinating experiment, the colour differences are remarkable. Thanks for posting.
