I haven't spoken to John my co-organiser yet about this but I'm sure he will agree . . .
I will be offering a FREE mirror ID engraving service. Security marking! I can engrave your name or Code number or whatever you like right onto the mirror surface.
No-one will steal your scope if they look down the OTA and see the mirror is security marked with big numbers.
I could even do a bit of engraved decoration around the Centre Spot for a fee
