ToUcam imaging of Transit?

Could anyone tell me what are the best setting for exposure, shutter speed,gamma, gain, exposure length etc when it comes to imaging the Venus transit using a ToUcam pro, please.

Hi Ronan,
The problem with exposure is that it could be different for different size scopes, I used settings which were fairly close to daytime settings,
but I try and not have the gain too high as \I tend to get grainy images if I do.
Best advise, practice before its here !
Have the gamma around the middle so not to over do it, I noticed with the halpha scope that you get MUCH better images if captured in black and white and colourised later in photoshop.
I might try this with the white light filter tommorrow to see if it has the same effect.

This is NOT manual SLR stuff we're talking about here. There is absolutely no need for you to take a note of exactly what exposure to use - the results can be seen before capture on your laptop and you can set the exposure then. If you are not familar with the software, plug in the camera and point it at your curtains or sofa, whatever (Point it outside during the daytime for testing through a scope and only at land objects). Look at how you can change the exposure and use the brightness meter on K3CCDTools to keep your exposure below 255 (saturation). Use your best judgement as to what brightness looks good on screen. Look at the automatic white balance and try using auto white balance initially, then unchecking when it looks right. All sizes of scopes will be different with different gain settings for the webcam. Keep the gamma at the middle - when testing your camera during the day you will see that gamma to centre is the most natural looking.

Test, test, test your system. Get familiar with the icons for capturing etc.

Good luck
