I just tried quickly this combination, with the Lunt DS unit 50mm after the Quark, just keeping in hand the unit and the eyepiece, so it was very quick.
Anyway I verified that I can get the focus, and the view seemed pretty nice. Now I'm going to get adapters, so that everything will be strictly fixed and I can try imaging too.
I could try also the Lunt DS before the Quark, but I wonder if the Lunt DS unit can be put after the optic without damage, I don't know exactly what filters are inside.
The optic is a 127mm, with the ERF filter.
Will update with the results!

Thanks Walter,
I agree with you in general, in this case I have the Quark and then the DS in combination, then I feel pretty safe, is it wrong?

Hi Marcello
you will have to make sure, that you cut away UV and IR, the etalons alone will not do that

You should only use the Lunt DS unit after the Quark, not before.

Re: Double stack; Quark + Lunt DS unit
Thanks Walter and Mike,
I will use that only way, the Lunt DS after the Quark. I don't expect any better the other way around.
In the Quark I guess that the first grey filter before the barlow cuts UV and IR
