Quark mod into combo

Post by DSobserver » Wed Dec 09, 2015 1:18 pm

hello

Did anyone already looks how to mod a quark into combo?

Andover 656.3 Å 1 nm would most probably be needed, but how to remove telecentric?

Regular Quark will work like a Combo (or even better) if to use it with 0,5x reducer.

Yeah, the whole black lens assembly just unscrews out of the quark body.

Yes Valery I have tried this and it works well
but what would screwing off the lens assembly do for you? (its a different approach)

Mark - still not precise enough
is the whole black part attached to the upper red part removed or
the inner 1.25 inch black stem?

No! All what is before the red cylinder is removed. Only red cylinder and 1.25" visual back remain in use.

once more do we remove the black lens
or remove the black lens + add a 0.5 reducer
or add a 0.5 reducer in front of quark

If we talk about the 3rd option, I tried : picture of the sun is nice but full of dust and picture of kind of broken piece of glass. I mean there is superpositoin of a focus sun + focus dust fromthe quark...
