If you image Venus using a narrow band of infrared light centred around a wavelength of 1,010nm, the planet's normally completely opaque atmosphere becomes almost totally transparent. In the nightside region, away from the dazzlingly bright day side, you can then ‘see’ the hot surface of the planet, with features that are at higher elevation being cooler and darker.
Capturing an image of the thermal night side of Venus is a challenge for amateur planetary imagers, mainly due to itsstandard planetary imaging and like a challenge, you can successfully capture this detail with your telescope.
