I could not see any stars in the sky with my eyes.  I could barely make out the moon.  Thanks for the suggestions.  I will try them next time.  I have done next to nothing with binning and read very little about it.  I bin 2x2 my Canon images just because I want smaller files to work with.

Unless the clouds were quite dense, you should have been able to image

than my C8 has and that Astro camera has huge pixels (2x the size of  

the TIS, so it can capture 4x the light) too.


If you were running the TIS in binned 4x4 mode and medium high gains  

with clear skies, you probably could have imaged  it at 10 to 15 fps.  

Your not so much concerned about image fidelity like one need for  

photometric observations with +/- 0.02 mag variations for asteroid  

photometric measurements,  your just looking for timing of when the  

event starts.
