I had a look through the Quark chromosphere model at NEAF in April. The view was impressive for the cost. Lots of surface detail and a couple prominences. I did not have a chance to look through the prominence model.
I had an extensive chat with the Director of Sales whom I have known for many years, and I decided to order the chromosphere model. I expect delivery in early June. I plan to put it on an 80mm f/9.4 refractor for starters. Daystar tells me that I will not NOT need a front ERF, nor a IR/UV cut filter for my intended use. If I look at the sun for long periods of time, the cut filter is indicated. If I use the Quark on a 100mm f/5, I'll need the ERF. I will likely use the Quark on both refractors, so the ERF will be a later addition.
This package suites my need and saves lots of $ when compared to a dedicated solar refractor (which I've been considering for several years). I'm really looking forward to having an H alpha rig at last.
