Oops. Yes STC filter. This is the best comparison I have of using the Duo filter, on the Tarantula.

First is 2.7 hours of 90sec lights with UV/IR filter.
Second is 2.8 hours of 6min lights with STC Duo narrow band-filter.

Ignore the difference in resolution - as the first image is binned 2x2, the second isn't.

Edit: the first shot is at f5.9 and the second with the duo is f5.0.
