I imaged Saturn with a Canon T2i DSLR camera and 2x barlow on an 8 inch SCT at 12:39 AM (Eastern USA time zone) on May 22. The camera has a sensor that includes 5184 columns and 3456 rows of pixels. By choosing the camera's zoom function one can select any 640 x 480 block of those pixels which is what I did to capture the video file for this image. The 2x barlow has special threads that mate with the T-ring of the camera.
