Are you collecting the scope or someone else? Would still be interesting to know if the effect is more to do with you or the scope? Perhaps repeat the test with two or three people sat in the shade, also get someone to go out into the bright / hot area to brin scope to you, ratrher than you go and collect it.
What time of day did this take place?
about midday... but i was barely out there for more than the time it took to bake it...
think a test in the tunnel would remove those possibilities though, if i get someone else to warm the scope up, the light conditions would be constant.
