This is done with the Baader IR685 that has allowed a few amateurs already to record details on the globe. Collimation set up directly on the camera, and the ser file recorded without limit. The image is a massive stack of 13000 raw frames (250 ms - 4 fps).
A french amateur, Flavius Isac, has recorded the belt (and the brightened pole) as well at the same moment with also a 10" telescope and the same filter :
