Quark spacing ?

[SAW]

Hi,

I am using the Quark chromosphere, interference eliminator and a zwo178mm. I've been told the eliminator works best at 17.5mm so I have got a 5mm spacer but I'm not sure if this should be placed between the Quark and eliminator or after the eliminator and before the 178mm 😕

First time I've heard of an interference eliminator. Is that the same thing as a tilter ? In which case the spacing isn't important, just the alignment. 

Have you a link to this device ¿

I agree that spacing isn't important and WOW that is expensive. My Rowan unit is a third of that price.

Isn't the spacing of the camera to the quark important ?

No, but the F ratio is.
