Mirror lens for reflected UV photography pictorialism style

Today about using an older, rather overlooked 250mm mirror lens for reflected UV photography. The lens had been modified to accept a filter in its rear mount and also modified to M42 threads mount due to its orgiginal special mount for cine use. The lens focuses now from infinity to very close, a pleasure to use but due to is long focal length of 250mm still tricky to nail focus.

A whiteish flower, a Treasury flower - Gazania rigens was used for that. Light was sunlight (shade after rain) plus some 365nm Nichia UV LED light .
