TOOLS AND MA­TE­RI­ALS

Sky at Night Magazine - - HOW TO -

TOOLS

Cal­lipers for mea­sur­ing the fin­der’s bay­o­net con­nec­tor and scis­sors for cut­ting out the tem­plate. If you’re us­ing a soft plas­tic tube like a film can, you will need a craft knife. If you’re us­ing a hard plas­tic tube then a multi-tool with a small milling bit is ideal.

MA­TE­RI­ALS

A right-an­gled fin­der for an SLR cam­era. A tube, closed at one end, that’s a loose fit on the po­larscope eye­piece – a 35mm film can or 36mm pipe end-cap may fit. The ‘loop’ side of some self-ad­he­sive hook-and-loop fas­tener tape.

SUN­DRIES

Card, elec­tri­cian’s in­su­lat­ing tape, per­ma­nent marker, bench vice, safety gog­gles.
