I'm glad your maths is as good as mine . Given the information that a SW 120mm in its case would be hardly more portable than a C8 I suggested a ( 4" ) 100mm refractor instead. I certainly wouldn't recommend the 120mm F5 SW Achro- having looked through one I cannot see it is much use for anything but low power wide field views .
