Hi Sylvain, and all,
Rare poster, long-time lurker. Modified a Toucam, back in t he days. I work mostly with a Canon Powershot SX50 with the CHDK modifications, these days, which, I think, not only qualifies, but deserves more attention within this group.

Hi,

I am currently testing two cheap CMOS webcams for mainly lunar imaging, and working with my partner Nicola (she is a brilliant programmer) on AstroDMx Capture for Linux. More details and discussion on the QCUIAG Facebook group. Please consider joining, it is a great place to discuss things and post results. You don't have to use it for any other purpose if you don't want to.

Hi Peter,

I'm glad to see that you are still looking at modifications of cameras─good QCUIAG tradition.? I can look up the SX50 but what is the CHDK modification?

I too modified the old Toucam, one bit the dust when the USB chip failed, but the other one, with modification and cooling still works although I seldom use it these days as KCCDTools doesn't work on my modern computers although the old Philips software does.? One strange thing I discovered is that the trick of raising the colour saturation to 100% to show up differences in lava composition doesn't work with my Imaging Source DFK camera nor (I think) my DSLR. I don't understand that─presumably something to do with the colour filters on the chip.

BTW there have been at least 21 others who have joined QCUIAG here since we did.? I don't do a lot of QCUIAG-type work these days but do experiment a bit with different optics.? I wonder what the others are doing.

Best wishes,
Peter

Hi Peter,
??? The CHDK mod. is actually a "firmware" mod. to the Powershot line of Canon cameras. In effect, what it does is allow one to access and control many aspects of this line of cameras to a much larger extent than the manufacturer "built in". For instance, the basic longest exposure is 15 seconds, but, via the CHDK system, I can expose for anywhere from seconds to hours, giving me access to phenomenal deep-sky objects, with everything from wide-field to 1200mm telephoto, all through a single, dedicated lens system.
??? Take a look at the system via Wiki, and here's a sample photo I took a while back of an Iridium flare, using the long exposure feature and a fairly wide-angle lens setting...

??? Do I have your attention now?

I have CHDK installed on two Canon cameras I use for normal photography.
