what gain

[bruno]

Does anyone on here use Nebulosity as their imaging program with a OSC, if so what gain do you use i have a zwo 533 pro.

My issue is  that the gain is in percentage but the counter is in numbers so  i have been setting the numbers to 150 which equates to 25% if i go higher  the image starts to blow out.

It looks ok but i just want to know if I'm doing too much, i also use an offset of 60.

Many Thanks

Anything above 100 will be ideal judging from the graphs, but much higher than 100 is maybe not that useful. You can use whatever gain above 100 as long as you wont saturate stars, but stars are easy to saturate so maybe dial it down to 100, or reduce exposuretime.
