Thanks for the reply Bojan
I always had this wild idea in my mind to overcome light pollution but based on what you explained, it won't work
.
The idea is to have a tunnel of visible lasers around the OTA of the scope which would stop the outside light from distorting the light gathered by the telescope and thus overcoming light pollution.And since a laser's light is concentrated, it shouldn't in theory affect the light gathered by the scope.
I think if i manage to save some money on the side, i will still test the idea on my small 2.5 inch refractor to see the outcome!Would probably need around 10 cheap laser pens....
