Reply To: QUARK Chromosphere and William Optics Z61?

Hi Paul,
I successfully use a Quark Chromosphere with a Williams Optics 66 and 81mm refractors for visual observing. I use a UV/IR filter.
While this works, it isn’t quite a quick grab and go setup as I have to wait for the Quark to reach the right temperature and sometimes tweak it to get the view at its best.
Best wishes,
Andy
