Quark DS : possible?

I'm looking to improve the quark.

Quark +PST is giving good results.

Any idea if Quark+quark combo would work better?

thanks

Mmh, a double Quark combo would give a 17,64X factor over the original focal lenght, i.e. more than 7.000mm on the little PST.
I think it would be really too much.

I was probably not clear enough :

I'm looking to DS my quark on my 152mm scope

Using Quark+FP from PST it works

but what about quark + combo quark?

Yes, sorry, I was slow to answer your pm

A quark combo on top of a normal quark would be an interesting experiment; just take the blockers off the combo so it is a bare etalon.

I believe it will be too dim.
