Thanks for the peek.

It is indeed. We've got a few scattered, low clouds today, but seeing is 4.5/5 this morning at 1015hrs. I've rarely used the 100mm, as the seeing has to be at least 4/5.Solsearcher wrote: ↑Mon Nov 30, 2020 6:07 pm Nice detail John , your sky must be improving out there

The little Z-61 is darn near impervious to degraded seeing up to a point, but itsFOV is way too wide for anything short of a full disk.
So, with a Quark it is not theaperture , but the focal ratio that needs to be considered.

All the best,
When I was "gathering" scopes for use with the Quark, I looked at the range of focal ratios that DayStar recommended.

All the best,F/ 32 , that is why they contain an onboard 4.3 barlow . The true limiting factor is the sky , because they are designed to operate at these long focal lengths conditions conditions become more critical . That is why many Quark owners quite often will have an arsenal of short tube frac's .
