Light pollition filter

[Tristan]

Living near the city sucks. So I'm wondering what light pollution filter works really well to get decent images through serious light pollution? Cheers.

I've used an Astronomik CLS, means longer exposure times to compensate for the blocked photons but works ok for Sodium and Mercury vapour lighting. May depend if your local lighting is being upgraded to led. Quite different spectrum on those and a lot harder to block.
There are a pile of others but I haven't tested any. Others will chip in with their recommendations.

Best solution for lp is very narrow band imaging

[Tristan]

I really want to do narrow band but just can't afford them at this stage. Looking for affordable options so I can actually get usable data to practise without traveling hours away.

If you have a background glow without a gradient then extra time imaging and lp filters can help, if you have a gradient it is extremely difficult to eliminate

[Tristan]

how do you tell the difference? what do cities normally cause?

+1 for the Astronomic CLS; best filter I have ever used , and on all types of objects even Jupiter!

Astronomik CLS as well. I used it with a DSLR from Sydney Burbs, worked fine though Hutech LPs is one that is highly rated as well. It makes a huge difference. Again, if a helpful council is upgrading your street lights it would have an adverse affect.

[rustigsmed (Russell)]

astronomik ccd cls for me too. I have heard the hutech is also good. what are you using? DSLR? astro modified or unmodified?

I'm Using a unmodified canon 1200D so a clip in filter would be great! Just gotta convince the Mrs

yeah no dramas, you don't need the astronomik ccd cls then just the cls (the ccd cls has an IR/UV cut which is more expensive - but not required for an unmodded dslr).
