Temperature

Doesn't matter where the point is, the emissivity is always between 0 and 1. And in reality, while determining temperature from incident radiation, it is the absorptivity that is to be used and not...

Equation

Emissivity of 1 implies blackbody. For gray or real bodies, value is always less than 1. \sigma is 5.67e-8 and not 5.67e-4. And this will return absolute temperature.

Incident Radiation

You can monitor incident radiation and then calculate temperature due to that using \varepsilon\sigma T^4.
