- 1sec looping
Bortle class seven, full Moon, 25° altitude, five minute exposures. No gradients, no coma and no halos. No need to refocus between filters. Nothing bad to say about this filter whatsoever. It works extremely well. It’s also amazing to be able to see the objects in live view with this filter and a monochrome camera (1sec looping) .The only thing bad is the hole in leaves in your pocket.
