Can anyone tell me any of the precautions or things to be aware of in terms of setting up laser equiptment outside during the winter, possibly in snow or snowy weather.
I am not sure the respose you will get from our support forum on this; our office is in Orlando Florida and we don't see much snow here.
I would register at another forum, Photonlexicon.com; there are many professional and high level amature laserists there and I can bet several of them will know what precautions you should take for an outdoor show in the snow.
