So I have continued to do some more tests on my 1600 cool and decided to investigate linearity since they claimed it is perfectly linear and I haven't seen any linearity graphs. Well... it is pretty dang linear. Attached is a graph with single image statistics. So in order to investigate the linearity to a greater extent, better statistics will be needed. But, it is pretty solid. I also decided on the listed ZWO driver settings because I found that it minimized my offset (minimized clipping in bias frames as well), and I purposefully shot for a DR slightly above the 4095 so that any fluctuations will not take my DR below 4095 and it also keeps other statistics minimized that would cause artifacts.
Since I am a student at an imaging science department we have integrating spheres and other tools to measure QE, so I am going to see if I can measure my system's QE with each filter so I can try to plan ahead more carefully since clear skies are proving to be a real rarity. Also... why not ? haha
Let me know if this helps any of you possibly interested in photometry since a big issue is linearity and it doesn't seem to be a big issue here.
