|Asteroids | Mag < 10: Avoid imaging if possible | ||
Planets |
These should not be observed with either FTN or FTS because they leave residual images on the CCD. | ||
Stars |
Depends on the magnitude of the stars. The exposure times for asteroids can be used as a guide to exposure times for stars. | ||
Bright Stars |
Stars brighter than magnitude 8 should not be routinely imaged without advice from the FT Operations Centre. | ||
The Moon | |||
The Sun |
The Sun is much too bright to be imaged with a Faulkes Telescope. The telescope will not allow this to happen. |
