Thanks to Steve and Gautam, the IMC was locked.
I was able to capture images with the Rainbow 50 mm lens at exposure times of 100, 300, 1000, 3000, 10000 and 30 microseconds.(The pictures are in the same order). These pictures were taken at a gain of 300 and black level 64.
Special credits to Steve spent a lot of time help me a with setting up the hardware and focusing on the beam spot with the camera.
I can't thank you enough Steve! :)

In the afternoon, Steve and I tried to install the camera near MC2 and get some images of the mirrors. Due to a restricted field of view of the lens on the camera, after many efforts to focus on the optic, we were able to get this image. MC2 was unlocked so this image captures some resonating higher order mode.
With MC2 locked, I will get some images of the mirror at different exposure times and try to get an HDR image.
