theres a big up side to imaging through the UHC-S but it creates its own problems too...
it will dramatically improve contrast but it throws the colour balance a lot and you will get small red halo's around some stars and you also lose pretty much all star colour when imaging through it.
you can pretty much think of imaging through a UHC filter with a colour camera as a '1 shot narrowband image' since most only pass Ha/Hb/OIII
