Hey Brendan & guys,
If only someone would volunteer to make + sell the little brass/aluminium adaptor thingy so all us useless twits wif no lathes could screw our guide cameras into our finders like you did!
PS, I bought a used DSI II pro just for guiding and it is far more sensitive than the QHY5. I'm sure it would match nicely with an 8x50 finderscope
