Hi Robin,

v.4.1.13835 - Running the Brain on the Player One 585c I come up with sky brightness of 8.5, noise @ 5% I get 3 sec and gain 210 for Max Dynamic and 30sec and gain 209 for Unity gain. Something isn't right.

Regards,
Don

Hi Don,

I think that's OK - oddly for this camera the cliff edge drop in read noise happens at pretty much the same point as the e/ADU hits 1, so the unity gain point is just on the lower side of the cliff edge, meaning both recommendations land in the same place.

If you have a look at the product page (https://player-one-astronomy.com/produc ... ra-imx585/) and scroll down to the e/ADU and read noise graphs, then you will see what I mean :)

cheers,

Robin
