For sale is my Daystar Quark, Chromosphere version. It has had infrequent use and I can't justify keeping it. Works superbly with my ED80. It was purchased in July 2017 from Widescreen Centre so is still well within the 5 year warranty period. I am looking for £625 posted to a UK mainland address. Everything is complete in the box including instructions, USB cable and power adaptor. Payment by bank transfer please.
Last summer I spent a lot of time observing and imaging the sun with a WO Z61 and Quark Chromosphere. Recently I have acquired a WO Z103 and if the sun ever comes out I would like to use this refractor for imaging as well. Question I have is with the wider aperture of the Z103, is it safe to use with the Quark and is an energy rejection filter needed?
I previously read that it should be ok up to c100mm without an ERF but I cannot see any reference to this on now on the Daystar website.
For some time I have been considering the purchase of a quark solar eyepiece, but I can't decide which one! It comes in two brands: "prominence" and "chromosphere", apparently each one is used to look at different bits. But it seems to me that both of these form part of the Ha experience. Of course, the ideal solution would be to purchase both - but that is impractical for other (financial) reasons. So which of these options is the best for "general purpose" viewing/imaging? Don't know!
So, quark-owners, which one did you buy and why?
