Hi Larry:

            I also just purchased a 1/3" Sony Super Had CCD 410,000 pixel
camera which has a resolution of 540 TV Lines with a minimum o.002/Lux
(intensified  recording b&w in this mode) or color 0.3 Lux (F1.3).  I need a
lens for it but have not ordered one yet because of our darned postal
strike.  I'm looking at this lens and am wondering if anyone has seen or
used one?

 

FUJINON:   YV2.8x2.8LA-SA2L   2.8-8mm VARI-FOCAL AUTO IRIS LENS
<http://www.prosecuritywarehouse.com/Art/spacer.gif> 

Our most popular auto iris lens, the Fujinon YV2.8x2.8LA-SA2L (Fujifilm) is
the fastest 1/3" high resolution lens in the CCTV industry with a f.95
aperture. This means that the lens allows more light to reach the camera
sensor yielding the best low light performance possible . The 2.8mm to 8mm
focal length provides a super wide range of adjustability. This lens
includes aspherical glass components for the sharpest possible picture even
with 540 TVL cameras. Includes a long cable with a connector factory
installed for the DC auto-iris operation. Very compact size. CS mount
cameras only.

Angle of view: 35 degrees (at 8mm) to 99.5 degrees (at 2.8mm).

Want superior results for nightime use? Select "for IR light" in the drop
down before clicking the add to cart button. This changes your lens to the
day/night version that includes coated optics that correct for artificial
and infrared light sources yielding a sharper low light picture. This model
is the Fujinon YV2.7x2.9LR4

          I was going to use the camera for another purpose but may just
give it a try for fireballs.  Let me know how well your camera works
recording colors?  Still looking for a 25 mm dia Gen 3 Image Intensifier at
a "reasonable" price.  Know any arms dealers that will ship me one in
Canada, ha! ha!  Promise not to sell it to a terrorist!  When in the
RCAF/CAF I held an HRP and Top Secret security clearance so I think I should
be trusted with one!  ;-0

Hi all.

 

Just discovered through some color subject musing & subsequent testing here
at YCSentinel.....

 

Wsentinel software with the Happenpauge Video card can produce (I think),
"reasonable" color on the brighter fireballs when coupled to a color video
camera. Color is not perfect but certainly very useable. (Standard Sentinel
III software does not allow any true color at all).

 

In my case, camera is a test Sony Hyper HAD color video camera model number
SSC-C104. It only has a 1/3" CCD substrate however, and is a 1.0 Lux camera.
It seems to provide a goodly wide angle with the Rainbow L163VDC4P All-Sky
lens in DC mode.

 

Light blossom (flaring) correction is VERY fast and there seems to be a
boost in camera sensitivity in dark conditions.....this I will need to check
more closely at night.....   

 

Wider testing for full potential of Fireball color captures needs to be
done, and there are much better video cards out there too.
