Flower Full Moon in reflected ultraviolet (UV) photography

Today is the spring full Flower Moon, the last Supermoon in 2020, which I have shot today in some foggy conditions in reflected ultraviolet photography using a special XNUV and the Baader-U UV filter. Lens was my very special 800mm LDM-1 KATOPTARON mirror only lens on my multispectral camera.

Indeed, the moon has UV reflectance and it can be recorded using proper equipment, which makes it nicely visible.

I have written about photographing the Moon previously HERE
 
Stay tuned, more will follow on that fascinating subject...

LDM-1 long distance microscope for reflected UV (ultraviolet) light and African Violet

Today shots of an African Violet flower in reflected ultraviolet photography using a UV filter stack consisting of SCHOTT UG1 + BG40. All shots were done at f11. Lens was a rather rare LDM-1(s) 800mm mirror only lens, the close-up using the AP300 achromatic cloe-up lens, which was once sold with this lens system. Light source used was a 365nm Nichia UV LED light.
