Which luminance or Light pollution filter?

Hi,

I want to use this broadband filter with my mono cameras and sometimes with my color camera, so i don't know which one of those filters i should choose? It will be used with a scope that might be not completely perfect quality, and with reducer that most of the time causing either halo or CA, not worry about Newt.
  1. L-Pro
  2. Astronomik L2
  3. Astronomik L3
  4. Just regular Lum as UV/IR cut
  5. Anything else i don't know about? [not narrowbanding multibanding filters please]

Hi

I'm not an expert in this topic, but I own an Astronomik CLS-CCD, L-2 and L-3 filter (for my modified EOS 70D).

The CLS-CCD is the classic light pollution filter which I used for years.
For me the L-filters are an addition to the CLS-CCD to gather colors in the range that is blocked by the CLS-CCD. 
See here the differences:

CLS-CCD:


L-3:


Do you have checked the graphs on Astronomik.com? The L-filters are almost in the same range like the CLS-CCD except of not blocking wavelengths between 520 and 620 nm. I think one of the L- filter would have been enough since they are really close in range. The L-2 surely is a good compromise.

Anyway, maybe some others can give you more specific information than me... I can only serve with the comparison CLS-CCD and L-3.

L-Pro. Best LP filter I know of.

Nice results!

As CLS-CCD, i already have IDAS D2, which is a light pollution filter which they made it to suppression LED more, and i feel like it kills a lot of Blue maybe or not giving perfect colors, i need to test and use it more to see, so i feel like i want something less aggressive maybe regardless of LED and LP.

L2 is like a general all around one, L3 is like blocking extended Red and Blue, in case if the scope or optics isn't quality enough, but i don't know if this will reduce the colors mostly in the edges i mean red and blue, it says it will reduce halo, i don't know if they mean halo or CA.

Ok, i think no matter what i should have it anyway, thank you

When I was researching what light pollution filter to get, I landed on the Baader IR-Cut Moon & Skyglow Neodymium filter.  In addition to getting one for my main imaging camera, I also bought one for my guiding camera.  I've had pretty good luck with it in my Bortle 7/8 skies in NE Ohio.  Really makes a difference and maintains excellent color on deep space items.  Works good on the moon and planets too.  

While I haven't tried the L-Pro, I have heard great things about it as well.

Ok, i have this filter but at 1.25" size, i will see if it can be ok with 4/3" sensor, definitely no for APS-C.
