Hi Jeremy:
Thanks... I guess it is a statistics thing, the more hours your exposure under the stars, the higher chances of getting something interesting.. The FOV is tiny 14x12 degree ... and the sky is so BIG..

We are clouded out on the DRA peak night also. Some reports of seeing 'elevated' activities were reported in Finland... Meanwhile Orionids and SPO will dominates...

Hi Siah heng:

a) wat902H b/w ccd + 25mm lens video f0.95+tripod+wood extend outside the window
b) Fast P4 PC, >3GHz
c) Japanese software UFOCapture V2 - DirectX based
d) USB 2 video capture card
e) BIG BIG hard disk space
f) place lens with long side perpendicular to known radiant showers.
at elevation 30-45.
h) run over night - from 11pm onwards till 6:30am ( software can be configured to start and end on any time combination).


Software does motion detection and registers movement in both peak-holds and full PAL frame rate AVI. A flash of lighning or birds across FOV
will create a 40-80 Mb avi files. 25-30 G space allocated per night

Hope this helps...

Most will choice a wider FOV like 6mm lens. FOr me i am interested to have a closer look of the meteor and hence settled on 25mm. Works well for my intention. Good for tumbling satellite imaging as well.

Will duplicate more completed system in future. fast PC needed

Hi:

1) watec 902H - used to be S$300-400, this is a noisey high gain camera but very sensitive for meteor. Watec 120N is overkilled. My Japanese friend all use Neptune 100N - I have one too.

2) 25mm f0.95 lens from avenir $800 is no longer available, equivalent from Japan is very $$ , you can get 12, 25mm f1.7 for around S$100..in Sim Lim

3) UFOCapture software is a shareware. Currently free for beta testing

4) USB 2 - S$170.00

So you are looking at less than the price of a good binoculars. $500-$700
with my guess of shareware SW costs throw in. For item 1,2,3

simply click on the underlined text "pretty video' or right click it and click "save link target as" and then choose a folder to save the file. you can play it using media player.
