Light Pollution Filters and the Moon

[RichieJarvis]

Hi All,

Does anyone know if a light pollution filter allows LRGB imaging during moonlight?

Just thinking, thats all...

Cheers,

Richie

I don't know about imaging specifically, but just as a general observation: somebody here recently suggested using an LP filter as a moon viewing filter. I tried that a few days ago using an LP filter which works quite well on the street lights we have round here, and found it did very little to block the moon's light. So I doubt a similar filter would help very much for imaging.

Richie, I wouldn't have thought so sadly, as the light from the moon is more or less right across the spectrum but a LP filter only works in narrowish bands aimed at street lamp frequencies, and they don't work for white light lighting.

What you need is the "minus moon" filter available for one day only...today

Can I get that at the same place as a 'minus street lights' and 'minus freezing body parts' filter shop!!

[adamsp123]

A minus clouds filter would be good

Apparently the Baader Neomydium filter is supposed to reduce moon glow, I'm not sure how it would do this since it is effectively reflected sunlight but it's what I've heard

Interesting....

I do have one of those - its been in my drawer for ages - must try it out!

Thanks Martin

I'll swap you my cloud filter for your moon filter!

The Neodymium filter is now on the nosepiece of the SXV-H9 - I've shot all filters through it, and it does not seem to have any detrimental effect I can see so far. Now all I need is a moon, to see if it helps with the LRGB imaging!

Watch this space.....

Cheers,

That might have been me who said that. I have used a SWLPF as a moon filter and found the view very pleasing. The moon was near full when i observed it and the LPF somehow gave better contrast to surface details that a moon filter doesnt offer when the moon is near full. Also the colour of the moon through the LPF was more natural and not tinted.

That's just my observations on it.
