(meteorobs) All sky cameras

[stange]

I have to agree with Chris and Thomas.

In the main, the PC164C's are superior to the Sentinel camera in both focus 
crispness and sensitivity by about 1 to 2 magnitudes. I tested both cameras 
with Sentinel software here under my poor Mag 2.5 City light conditions.

Using my Sentinel at a higher software brightness level of 150, (where 128 
is the normal range), I can routinely detect fireballs of mag 0 and 
sometimes mag 1. Basically it will detect fireballs almost as dim as the 
dimmest star that is visible in your starfield if your sensitivity setting 
is close to your threshold setting. Unfortunately getting too close to 
threshold settings cause false triggers from other sources.

So for this station in Yuba City..... mag 0 and is the limiting magnitude.
