Alternatives to SI and Sumix

Wayne Morellini · February 16th, 2005, 11:02 AM

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.

Wayne,
You mean something like this page?

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:

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.
