I found with my GS 30mm SV that seagulls flew all around 30% of the perimeter stealing my hot chips.
Then after leaving it out of the case for about half an hour the seagulls had flown away. Methinks it needs cooling as much as the scope does.
Once the SV cooled down it was magnificent. Excellent eye relief and it looks impressive when the visitors come!
I won't be getting rid of mine in a hurry, if ever.
