What are the limiting factors in this case.... Hello, I have quite recently shifted to this area in Thailand. This is a very small town, there are no big cities for more than 150km distance, & no special industrial towns nearby. Before coming here I had thought this will be a very good place for sky gazing even with naked eye, but surprisingly I have found it all opposite. The sky is extremely dark and I can't see anything except moon with an unaided eye. I Haven't been able to understand why... I think I don't know all the limiting factors which simply block easy watch of heavens. I'll be thankful for your replies.
