I live within a couple of kms of the centre of Perth and the skyglow is to say the least a pain. I used to live, until fairly recently, in a considerably darker sky region 35kms south of CBD ( I miss it a lot ). Anyway due to relocation I am now thinking about filters to compensate for the polution.
I see Bintel have Orion Ultrablock filters that they claim do the job very well at a fairly reasonable price also Lumicon and Baader have filters ( generally higher prices ).
Your thoughts ............ thanks !
