Venus Image 2016/10/05(UT)
Anthony Wesley (406mm Newton)|
The left image was taken using an Astrodon UVenus filter
and the right image was taken using a Thorlabs 1000nm longpass filter.
Very different cloud structures are visible through each filter.
The UV image is very seeing-sensitive, so I hope these will improve as
Venus gets higher in the sky here in the late afternoons.
It's noticeable how both filters show dramatic changes in cloud structure from one day to the next.
