ASI183MM-C Offset

ASI183MM-C Offset was created by Thomas Jäger

Hello Forum,
if I use the ASCOM driver of the ZWO ASI183, no offset setting is provided. Under INDI, an offset setting is possible.
In some cases I switch between INDI and ASCOM for the same deep-sky object. What is the right offset setting here?
I use gain 53.

It would probably be best asked on the ZWO forum, but I am pretty sure Sam and company have locked the new cameras at 50 offset.

Good information. Each camera has a different fixed offset then. That makes it fun :)

You are right.
I was skeptical and went into the lab. I did 31x bias frames with each setup setting offset to 10 in the INDI Driver. Sam was right.
