Venus in infrared and ultraviolet 9/13/21

Here are several images of venus captured with infrared and ultraviolet filters. UV  light shows cloud structure which cannot be seen in the visible spectrum while IR in this case gives a sharper image, but no cloud detail:

Venus IR as red, UV as violet 9/13/21

the seeing was fair to poor.  my intent this day was to image mercury, but i could not locate it during daylight with my overloaded mount.  here are the raw stacks with two different IR pass filters one at 685 nm, the other 850 nm.  the 850 being further into the infrared is generally preferred for mercury or poor seeing conditions, the latter being the case here:
