Stars have ranging colors from very blue, through the spectrum to very red. Placing a value from 0 (very blue) to 11 (very red) I've observed ten different stars. Those ten stars all come from either Ursa Major or Ursa Minor because I find that those constellations are easily located. Here is their assigned number:
The brightest stars seemed to be Dubhe, Alioth, and Alkaid. These stars were light orange, white, and blue-white. I think that blue-white and white are easily seen because their wavelengths are stronger than that of yellows and reds.
The most difficult colors to detect were stars like Pherkad. This may be because orange is a less-powerful wavelength or simply because Pherkad is so far away.
Overall, I found orangeish stars to be the least brightest stars that I could detect a hint of color. To me, orange almost seems like a darker color than white or blue-white.
No data showed up. Did you try brighter stars like Arcturus, Vega, Antares? Pherkad is a bit faint to see color (regardless of whether it is blue or orange. I need to the data to gove you points.
ReplyDeleteThe data should be in the image:
ReplyDeleteSPECTRUM SCALE: 0 = Very blue - 11 = Deep red
STAR COLOR STAR COLOR
Dubhe 7 Mizar 4
Merak 3 Alkaid 2
Phecda 3 Polaris 3
Megrez 4 Kochab 7
Alioth 3 Pherkad 8
What day did you go out to make the observation? How did you know which star was which? Need some more info for points.
