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.
