Those yellowish street lights (Sodium) are the bane of every backyard astronomer.

The blue (Metal halide) arent much better.

They do make filters that cut that particular part of the spectrum but it diminishes the light gathering of the scope.

My scope is a hand made 6" f8 dobsonian 100% manual

I did buy the mirrors though

Ill get some pictures up, in fact I just stripped her down from her summers rest so shes torn open and Ill get some of the innards.

Ill start a new thread for that.
