Hi everyone, Ive just recently got a 10mw laser pointer from Bintel & while I was using it as a hand held pointer to show people the night sky it worked perfectly, but as soon as i mounted it on to my scope and used it in cold (below about 9deg C) weather I could barely see it if at all.
I had to resort to a hair dryer to warm it up every 5 minutes.
I had heard that lasers can be affected by the cold but another observers 5mw worked perfectly all night without a hint of it being affected.
Is this common? or do i have a dud pointer?
If its just how they are does anyone have any ideas on making a pointer heater? maybe like a dew heater ?
Any suggestions would be appreciated
Simon
