Hello,
I am trying to create an imaging system on SkyTools Imaging for my new smart telescope Vespera Pro to get an idea of the SN ratios for exposures but I am getting very off results. The system is a 50mm f/5 quadruplet with a Sony IMX676 Color CMOS chip. The usual subexposure is 10 sec but can change up to 30 sec but is not recommended because causes tracking problems, the systems basically stacks subexposures and tracks on the fly, and the usual gain 20 even you can manually change it up to 27. I am trying to estimate the ADU for the gain and I think that is what I am doing wrong. I look for information on the chip online and I estimate a 2.3 e/ADU, reading noise of 4 and full well of 74000.
I will appreciate some help figuring out the sensor parameters or if someone else had success creating a imaging system for this or similar telescope let me know that they did.
Clear skies,
Carles
