Re: Cold weather etalon performance

Thanks Brian, I'm near Fort Frances, in between Thunder Bay and Winnipeg. We moved to a lake home that has some great skies, but there are temp extremes. So if I ordered a Lunt 60mm say, there is a VG chance it will work right out of the box? My Quark had to be tuned for my set up and temps...we'll ...

Cold weather etalon performance

I'm still tossing around another Ha set up besides my Quark and have a few questions. My weather here is extreme- right now its -26c with a bright sunny sky and with some VG seeing around here. Will a Lunt 60mm-internal air spaced etalon come on band from the factory? I'm at 1100ft with temps from +...

Re: Quark visual image too dim, please help

Re: Quark EP issues ?

The 32mm TV plossl has a difficult eye position as the exit pupil is extended past the eyecup. An eyepiece focal reducer screwed onto the 32mm TV pulls the exit pupil in and gives a nice useable reduction. My favorite eyepiece with the Quark is a zoom with a 19mm field stop @ 25mm and used with the ...

I have received my Quark back from Daystar and it is working well- no banding, for visual at least.

I watched the event starting as a triangular solid lump on the sun, to the jump and disappearance. The view through my Quark 90mm SV APO was photographic like- very high detail and sharp as a razor. The SW120ED upped the view again. Great catch ishua! I hope some others caught it too.
