unmounted filter orientation
I'm using the Baader 50.8mm unmounted LRGB set and by chance came across a reference on Cloudy Nights that they are direction specific. Apparently the newer ones have arrows on the edges showing which way they go, but otherwise you need to look at orientating the shinier side one way or you could have reflection problems (The documentation from Baader says towards the scope but many posters say towards the camera - not too helpful). Well I have been noticing some troublesome halos in my blue subs so thought I'd open up the filter wheel and check. In the end it was pretty much impossible to determine which side was the shinier one. I flipped the blue one to see if it will have any effect and took the opportunity to blacken the edges of all of them. Time will tell. Does anyone know a definite answer to this?
