ASI174MC Cool and software worries

I'm just starting a new season and upgraded many software (including Win10). Also upgraded newest software (ascom drivers) for ASI174MC Cool.

Don't know if it's software related but it seems something is now different.

Attached is image of M57 60 x 1s exposure. Strange vertical patterns.

Which ascom camera to choose 1 or 2 ? What's the difference ?

What's the optimal offset ? Optimal gain ? Recommended settings ?

Hello,

What camera control software are you using.

Sharpcap can control ASI cameras using Direct mode and does not need the ASCOM drivers.

Jason.

2 ASCOM is used to control 2 cameras through one software

either one should be ok for you

the pattern seems may because of movement of your image

Don't believe there's so much movement in 1 minute.

Have a reasonable decent mount (CEM60-EC).

did you subtract a dark?

This image is not dark frame calibrated, if I remember.

you need to subtract the dark if tracking too accurate

because the stack software may stack on the Noise

or just use dither
