That is why you can get cameras for $1000 USB (I said it wasn't pretty), and you can figure the rest from there.

Obin's is only going to be one of many systems. A secondhand f1.2 35mm lens is $50 (or cheap CCTV lens) and make an adaptor. Rob's software (when finished) is supposed to be $100 (I think), and he Sumix system will hopefully have the software in their system, and for their existing $1000 camera. But well see what happens.

Of course the editing system might add some price, but that is not the camera system.

I know this is not what we are after but it might give some ideas.

John, this is a great find. RAW camera mods for web cams. We now have high speed, descent latitude, HD webcams out there.

I'm sorry I missed this back then, I was getting so overloaded with links I still haven't read hundreds of them.

I have just been looking for hours (now morning) for a link to a Astro site listing all cameras and there performances, I thought posted by Ronald in the Technical thread, but I haven't been able to find it. I mention a list in this thread, but I can't find one in this thread, would anybody here know where it is?

Thanks

Wayne.

Yes, something similar to that but for all sorts of cameras, not just web cams. I tried googling for hours, and lots of useless hits. Do you know some good Astrology sites with a good links list, that you could refer me too, they might have a link?

What I am trying to do is find is sensors/cameras with the most sensitivity and latitude for a uncompressed camera experiment. The cameras have to be at least 426 pixels across, 640 or 720 pixels across preferably. Web cams are far to limited in range. I have found a nice imager, for satellite use, but the truth is that it is probably goign to cost a fortune in a camera, and might not be they best either.

I have been following the links on those pages and have come across some stuff and started another thread on the web-cam mods with the new links:

http://www.dvinfo.net/conf/showthrea...118#post455118

I did not find what I was looking for (lists of info on all cameras and sensors, not just web-cam or firewire), but I did find some helpful short lists (0.00015 lux cameras and a 200K -ev well capacity sensor) that might help.

Not at this time, but if I found such a site I'll post here... or may be better in your new Web Cam/RAW mods for Astro, Digital Cinema camera use? thread?

About the high sensitivity camera - DXB-9200EX is a good one on paper and theoretically you can replace the sensor in a CCD webcam with this one and use the USB2(IEEE1394) connection already on webcam.
Two examples:
a Sony ICX414 onto the front end of a standard modified webcam
replacing the ICX098 CCD in the Phillips Toucam with a ICX424

Be aware that the Philips SPC900NC (one of the most expensive webcams today) is a USB1.1 device! VERY BAD because the sensor is quite good - Philips SPC900NC
Some e-shop sites claim that this webcam is USB2.0 and capable of 90fps,but when i see the screen shots from the drivers interface, I see 640x480@15fps is the maximum!

Thanks for the links and advice, I will have to leave it for today, as I am not feeling the best.

About those web ads advertising 90 fps, they might have confused a small sub windowing rate with the full frame rate.
