“I read that quark HA have two models depending one viewing target (prominence or chromo), and are $1000 a pop, what's your experience with that? do the lunt and solarmax have a continuous tune to either target?”
I bought a Quark Chromo from Jen at DayStar. She was at HOASP set up selling quarks.
Her recommendation was to get the Chromo for best results in observing both surface and proms. I believe it was the right choice as I enjoyed it on my WO 132mm .
You don’t seem many Prom Quarks for sale on the used market as Chromo.
Good choice if you have a refractor .
“I love your idea of the binoviewer. These cut 1" in aperture I read, which isn't a problem with solar viewing what do you recommend?”
Ive never heard that Binos cut an inch in aperture?
I do know that bino viewing with my Lunt 100 greatly increases the contrast so it helps with seeing details. I don’t observe with out them, big difference.
‘doesn't pointing a scope to the sun risk damaging the inside because it's black? or warp the mirror? Or perhapse there is a primary filter that you put at the entrance of the scope that prevents overheating... or maybe that's why you mentioned a refractor and not a Mak
what's the difference in viewing between a quark and a dedicated?”
I believe with knowledge and proper filtration refractors are safe , never had any need to try a dob. I’d guess that maybe an aperture reducing mask they could work well, someone else may have some experience here.
A Quark has to be installed on a refractor of an acceptable F ratio to work, Mine took 6 min to come on band after an adjustment. I sold mine to get a dedicated solar scope for easier setup, my Quark and the WO132 did not provide a full disk view , amazing detail but no full disk.
Thats another reason for the move to a Lunt 100, full disk and lots of detail. Just got a DS but have not used it yet, that will provide even more surface detail, contrast.
Just my experience from a visual observer
