Re: Issue with ASI1600MC-Cool and DSS

Those look like hot pixel effect. Did you use same gain/offset values with both lights (and calibration frames) ? Also was the stacking method same - average, sigma stacking ? You can correct those with cosmetic correction (in DSS), but darks should take care of them anyway. Didn't know you could bi...

Also you might need to adjust USB limit.

Re: random "hot" pixels

So this is dark frame ? How long exposure ?
Have you tried taking real lights and then do calibration - how does the end result show up ?

Looks ok in smaller image but big resize shows jpg artifacts (=too much compression).

Re: ASI017MC and Gradients

Does it happen every part of the sky?
Could it be light pollution or moon?

Re: Problem with sharpcap upgrade to 3.0 using ZWO camera

If it works in daylight it should work at night.
You adjusted exposure/gain at night, right ?

Re: ASI224MC expected FPS when capturing

If your exposure is around 0.1s you can only get about 10 fps. If you want more fps you should decrease exposure - alas this also means you should increase gain (or buy bigger aperture scope so you get more light). Also you could use ROI so you don't get useless black space - this means your files w...

Lowering USBTraffic to 40% doesn't mean that your FPS reading gets down 40%.
What is your exposure values when you get 0.2 FPS?
