Clarification needed for capturing Flat frames

[admin]

Hi Edmund,

the histogram screenshot that you have included looks fine - you have done your best to keep it away from the two ends in spite of the blue illumination being considerably less than the green and red.

I'm not sure if I really understand the second part -if you are getting warnings about saturated pixels then your histogram must look different to the one shown with some pixels at or very close to the right hand end. If the number of pixels above 95% is very small (single digit total) then you can probably ignore the warning, but if it is a significant number then the exposure needs to be reduced.

I think I can also see from your screenshot that you are running an old version of SharpCap (there is no 'zoom' tickbox to zoom the histogram), so it may be worth updating to the latest version.

cheers,

Robin
