Hi !
I bought a ZWO ASI120MC camera and I use a c# / ASCOM program do get camera imagens. I want to read RGB vaues from each pixel.
My problem is when I execute Ascom method Camera.Choose(...) appears one window to choose camera settings and at IMAGE TYPE dropdown, there are only options for grayscale Image Type (RAW18, RAW8) The option for color image, ImageType = RGB24 is not available for selection.
I posted in ascom forum and friends of mine with same code but diferente ZWO ASI cameras has RGB24 available for selection. Both cameras are Color cameras.
Can you help me ? I am completely lost...
Thanks in advance!
