Good luck Mark.
Systematic testing and subsequent evaluation will be time well spent.

Re: Brightness and White Balance Adjustments after Smart Histogram Brain
Folks If you follow this plot at some point will you not start clipping the white point? Yes, therefore intelligent use of the histogram is required in combination with the settings. With an Altair 183C capturing at 5000x3000 I usually push it and end up with a small number of pixels at or around 10...

Re: Brightness and White Balance Adjustments after Smart Histogram Brain
Mark I don't autoguide so it may not be possible. Don't be in a hurry to go down that route - look at the basics first. I have a Celestron AVX mount, 2nd hand, cost me £500 (£800 new). I use it without guiding. Good reasonable polar align via polarscope, careful 4 + 2 mount alignment, then All Star ...

Re: Brightness and White Balance Adjustments after Smart Histogram Brain

Gain=125 looks an interesting one from your graph. 2) yes 3) exposure same that planned for lights when capturing darks 4) match dark exposure when capturing lights but you might have meant that anyway 1 - 4...

If you download and run https://www.uwe-sieber.de/usbtreeview_e.html we can soon find out the USB chipsets in the machines. Post back the graphic image in the left hand pane of the application for both machines.

Re: Brightness and White Balance Adjustments after Smart Histogram Brain
Mark
Can you post a couple of example FITS Liberator images as above. Also an example of a bimodal one - I might have seen that before, I will have a hunt round in my old data. What colour space is being used?

Re: Connecting multiple ZWO cameras
Got that Carl. You are struggling with Renesas v1.0, things are rough here with Renesas v0.96. Useful to confirm that particular chipset is troublesome.
