## Methods The purpose of this investigation was to compare the images resulting from different exposure times to the recommendations listed for the Faulkes Telescope.

Object Type	Lower Limit (seconds)	Usual Exposure Range (seconds)	Better Images (seconds)
Galaxy	30s	60s	120+s
Nebula	30s	60s	120+s
Star Cluster	2-5s	5-30s	Ask for advice
Planetary Nebula	10-20s	30-40s	Ask for advice
Asteroids	Mag <10: Avoid imaging if possible Mag. 10-13: 20s Mag. 14-16: 30s Mag. 16-18: 60s Mag. 18-20: 90s Mag. >20 please ask for advice as other factors may influence your observation.
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 Moon is too large and too bright to be imaged with a Faulkes Telescope. See the Field of View link on the right.
The Sun	The Sun is much too bright to be imaged with a Faulkes Telescope. The telescope will not allow this to happen.
