Astronomy
I completely agree that anyone who deliberately shines a coherent light beam at an aircraft should be jailed.
However, whilst I am not a fnantical astronomer it is pleasant to take the telescope out on clear nights and see what is out there. Laser sights are really most useful in acquring a good position and the more coherent the light then the better the alignment. I have both red and green lasers but there is a flight path due south of me so although I try to be careful it is possible I might shine a laser at about a right angle to an aircraft on approach to an airport.
I would apppreciate some comments about this -
Is even a momentary exposure enough to cause problems?
Does a laser have much effect at oblique angles?
In general do astronomical lasers cause problems? ( I dont mean the huge things that professional observatories have but simple domestic set ups such as I have)
