Hi, Im writing my own autogain routine for the asi294 and I'm having trouble calculating the gain of the camera. I see the gain figure on pg 9 on the asi294 manual which can be found here:
https://i.zwoastro.com/zwo-website/manuals/ASI294_Manual_EN_V2.2.pdf
Im assuming that by ADU this corresponds to an ADC count. However, since the camera can switch between 14-bit and 12-bit by switching to High and Low speed modes, a single count has a different resolution in terms of reading a pixel voltage. So I'm assuming that the ADU changes with resolution. So I'm assuming that the ADC resolution is 14-bit for the figures on pg 9 and not 12-bit.
Additionally, since the figures on pg 10 are for the unlocked bin1 mode, that the figures on page 9 are for the bin2 mode. I want to use the bin2 mode.
Questions:
1) If ADU and counts are the same, what resolutions do I assume for the plots on pg 9?
3) What happens if the return image is set to 16-bit, does this mean that the maximum counts at saturation will only 14-bit or 12-bits depending on the speed of the image?
4) If I used the 8-bit image format, the ADU is how rescaled to 0-255, the gain in this case would also be scaled differently. How would I calculate this?
Could someone please walk me through with the calculation? The setup that I'm using is bin2 mode, Fast mode (12-bit), and 8-bit images
Much appreciated!
