LP Filter map newbie question

[sirmetin]

Given that light polution filters work well depending on the predominant street lighting in the area is there a map showing the areas particular filters work well?

Use the 'Search' button at the top of the screen, lots of info on LP including LP Maps and Dark Sky areas.

Good luck

I haven't heard of anything that specific, but need-less light pollution is a good start for pollution.

See In depth | CPRE for a map published by the CPRE.

I don't think there is such a thing. I've never seen a map broken down by pollution wavelength. In addition, it may be very dependent on local pollution and the maps are quite low resolution.

Finally, and most importantly, the different filter types aren't optimised for pollution type but for DSO emission lines. The whole idea is that, say, the band-pass filters block everything but certain lines (OIII or Hbeta). You choose your filters according to what you want to observe. There is no provision for choosing filters by pollution type and this probably wouldn't be efficient in any case.

It really is a shame we don't have the 70s power cuts anymore !!!

Hey what about those of us who use the electric to power our laptops, cameras and mounts :-)

Big deep-cycle and an inverter--bingo!
