SharpCap Forums

Hello,
From what I have read, it appears that in proposing exposure times, gain, and the number of sub-images to be taken, The Brain does not need to know the brightness of the target object, and is trying to capture the faintest detail just above the noise level. Is my understanding correct?
If so, then when imaging a brighter target I assume that I should use The Brain’s suggestions and then analyse the histogram and make changes to the settings accordingly?

Speaking of histograms, it seems that you can’t use SharpCap’s histogram to analyse a captured image(?) Being able to do so would be an advantage to me.

Hi John,

you are correct that the analysis looks at optimizing for brightnesses at or just above the background sky glow level. This is usually a reasonable thing to do as even with a significantly brighter target you want to capture good details in the edges/fainter parts of the target, which are typically only slightly brighter than the sky glow.

If you want to look at a captured image in the histogram, you can use either the 'Test Camera 1 (Deep Sky)' or the 'Folder Monitor Camera' to reload a previously saved image into SharpCap as if it had just come from a camera. It's a bit of a workaround, but it should be usable.
