Cookbook for getting good Images

[Tom Droege <tdroege@veriomail.com>]

It appears that I am learning how to get frost free images.

I turn the system on 4-6 hours before sunset.  I set the gas flow for 
several bubbles a second.  Less and I get ice crystals.  This uses up 
Driright, but it is cheap.  I think this is a question of how tight the 
particular camera is.  The I camera seems to never get ice, the V camera is 
more vulnerable.

I run for several hours warm.  I just set the DAC at 9 and this mostly 
turns off the current.

I then turn on and run at the command temperature and run several hours 
before sunset.  I find that if I don't do this, it often fogs up.  The fog 
wears off later in the evening.  But then one has lost good data.

So far tonight, the data looks to be very nice.
