Solar Activity in Ha with the Tal100R Refractor - 17th June

I have found a bit of an unusual setup that I quite like in this years solar season; my trusty 100mm Tal100R refractor works particularly well when my double stacked Daystar Quark is used in conjunction with the 0.7x Baader solar telecompressor and the PGR Chameleon 3 camera with 2x2 binning.  This unlikely combination delivers a f43 beam into the etalons for a contrast rich view, the solar telecompressor then brings this back to a more manageable 3 metres focal length, which on days when the seeing is too bad for the 0.2m Airylab HaT gives some nice views.  Our star was looking very fiery with this setup on saturday.
