The 13 certainly lets more light through and more stars which might be better for cameras with on board guiding.

The new line of Astronomik filters has addressed that issue, they are all now ultra low reflection.
I have a new set of LRGB's coming next week to match my new low reflection narrowband set I already have err?..which I haven't had the chance to use yet
..at least they are installed in the filterwheel
...although I will have to dissasemble again and remove the LRGB when the new set arrives
...oh sigh...just wanna image man
