(meteorobs) 2008 Orionids

[Ed Majden]

	Depending on the specs you look at these cameras have the same low  
lux sensitivity 0.0003 at f1.2 - 1/60 sec.  What we need is a camera  
where you can control exposure length, i.e. 1/30 sec or better 1/15  
sec exposure.  Such a system may not be more sensitive recording  
moving objects (meteors) but they should be capable of recording more  
background stars for reference points for measurement.  The film  
based MORP Cameras used chopping shutters with a chopping rate of 4X  
per second.  A bit on the low side for velocities but Ian Halliday  
used these rates successfully for his Fireball Network.    Anyone  
know where one can find a video camera with low lux capability with  
exposure length control that will not break the bank?
