Gary / Jeremy, I’ve never made a meaningful observation of anything the VSS is interested in. What sort of settings would you recommend For a DSLR at prime focus? I think the FoV will be too wide with my 80mm refractor  so May have to jump right up and use my C11 and Canon 6D. I think I can get to a site with a low northerly horizon that isn’t too light polluted; but 3am though, whose idea was that?!?!?! 🙂
