Hi,YK CHIA
Salute to your effort and your equipment.Looks to me that your equip can detect very dim and fast meteor.For such meteor general camera register it as a flash of light indistinguishable from moving small clouds.Thanks for posting .Comparing allows me to truely know the limit of the camera.Thanks.

Hi :
I got a chance to compare visual vs the wide angle video detection on 4 meteors on the recent Perseids. Yet to do likewise with digiSLR.. perhaps the next shower coming up.
I believe as long as we get mag 0 1 or brighter meteors with comparable or smaller FOV and exposure not too long to over exposure digiSLR can registered similar trails.
p/s yes the video is sensitive sometimes too sensitive( level selected in sw program - it even picks up AC noise when members turn on /off a lighting switch or other tiny random cosmic ray blip.

Hi,YK CHIA and other meteor lover
I guess I come to the conclusion(after 3 yrs of testing) that even at iso3200 to ensure a GOOD catch of a meteor on photo requires it to be as bright as saturn or mars at its brigthest.Otherwise those atmospheric glow of the Singapore sky will get it confused as a passing cloud--iff you are using an ordinary camera like mine;however if you are using highly pro stuff then you can detect even very weak meteor.Any comment?Thanks.

Hi YkChia,
Very nice video esp of the bright Perseid at 2.32am! That one was a dazzler!
I got up at 1.45am that night (right at the projected peak period) to try catching the Perseids. However, it was very cloudy. So I went back to a half sleep for the next hour, and got out of bed again just before 3am, when it was less cloudy.
However, after about half an hour of sleepy observation of the northern sky I didn't manage to see any meteors, so I went back to snoozing.
Hmmmm....
