Does my sensor analysis graph look 'normal'?

Post by abmscopes »

Hi, apologies if this sort of question gets asked a lot... This is the first time I've run sensor analysis. The results look a bit odd to me (not quite sure why other than they don't look like the one in the Sharpcap tutorial !

The first time I ran the analysis it ran to the very end before returning an error after the binning tests. I then ran it again and it completed but the sky was darkening by then so I guess the light levels may not have been constant enough?
Camera is a OSC ZWO 294MC.
Thanks!

Hi,

the general shape and rough values are about right, but the fact that the values are jumping around a lot (especially the read noise - the red X's) is not right - it can happen if the illumination levels were varying during the final stages of the analysis when SharpCap is measuring the relative gains of the camera.

cheers,

Robin
