light pollution
Hi all,
How do you know how light poluted your sky is? Silly question I know but I only ever observe from my backyard and I can usually see alot of stars and objects with the naked eye, but sometimes objects are very faint through my 8 inch dob. Like the Sagittarius cluster is very faint but I can easily pick it out, so basicly is my sky ok for observing most objects? Is there a way to test light pollution?
Thanks all
Dan
