Sorry Guy's
I think this tread should also contain a warning:
DO NOT LOOK DIRECTLY AT THE SUN THROUGH ANY OPTICAL DEVICE WITHOUT A PROPER FULL APERTURE SUN FILTER.
INSTANT AND PERMANENT BLINDNESS CAN OCCURE.
I appreciate that most people using this Forum will know what is required, but, you don't know who is browsing.
Cheers
