Here is Camping Mat I used

(And got roll of Unibond Duct Tape from Asda for £2.99 (you can use Velcro if you prefer))

Cut to circumference of scope, tape at the seam where edges meet leaving a tape width at bottom of shield that goes over end of scope, overlap and tape so its tighter than rest of seam this will make nice tight fit and prevent any light from escaping
