that's beautiful, I have IDAS P2, UHC Lumicon, Baader Neodymium filters with 130PDS (my new tube). 
Due to the cloudy weather, I could not make test. Could you give some feedbacks about how you use them.

What filter for what use or what is the best compromise use. Thank you for your feedbacks.

Hi Kaelig,

Thank you. It is hard as it depends on your local light pollution and the type of light pollution you have. I have pretty bad light pollution which is why i use a tri band filter for nebulae to get the most detail, The neodymium will give you a more natural colour than the p2 but the p2 will be better if you have some local light pollution in my opinion. I cannot comment on the Lumicon UHC as i have never owned one

I would suggest when you have clear skies to test each filter on the same targets ( as well as no filter ) pick a Galaxy and a nebula then compare and see which one you prefer. Galaxies are broadband so using a filter will cut out some of the light and you will lose a little detail but if your local light pollution is overpowering the 'no filter' approach it may be beneficial to use a filter. I live in a bortle 8-9 area and i find using a p2 filter on Galaxies beneficial to me. Hope this helps a little, good luck

Many thanks for your clear answer, the weather is very cloudy since a month, but I work (in theory) on the subject.

I will test:

- baader neodynium

- IDAS LPS P2

and a test with a complementary filter

UV/IR cut TS filter + IDAS LPS P2 ~ IDAS LPS D1 (no available, they have stopped the production)

For the moment, I wait some deliveries & clear skies in order to test (following your advices)
