I need help

Bio,

Yes I know, thanks for explanations.

Can you tell me if that program tells you the possibility of seeing the Gran Sasso d'Italia? Its far away, but with height of 2900m it could probably be possible.

PS: I posted reportage here: http://forum.meteonetwork.it/showthread.php?t=9216

The analysis indicates that Gran Sasso (Corno Grande 2913 m, heighest spot elevation of Appennini, 373 km far from Mt. Nanos) is not visible.
Instead the analysis set the top of Mt. Terminillo (2216 m, 380 km far from Mt. Nanos) as visible.

I think the obstruction of Gran Sasso is due to some low croatian relief (35-40 km far from Mt. Nanos) that falls on the line of sight Nanos - Corno Grande.

By the way the top of Mt. Terminillo is the farest earth surface area the software indicates it as visible from Mt. Nanos, but I can't say this is 100% OK, because all the problem play around the value I give to the refraction factor.

Only you with your eyes could confirm or not

PS: I've seen your photos: simple... fantastic
