can you use planetry filters as nebula filters of so what coloured filters are best for nebula

[TheMrGecko]

Do you mean RGB filters? designed to make color images from a mono camera?

Or do you mean filter designed to boost the contrast of planets?

I suppose it might do. Wouldn't work as well as one designed for nebula use I cant imagine but probably better than nothing. Please try it out and report back. I'm interested :)

would it be red blue and yellow filters I should experiment with

Can you be more specific about what you mean?

The Baader Neodymium filter is the only thing I can't think that has dual use like this

Wratten colour filters wont enhance the views of nebulae at all.  

 

[Dave In Vermont]

The standard for viewing nebulae are the narrowband-filters - UHC & OIII types. Colour (Planetary) filters are not likely to do much. But you can always experiment.

Here's an article from David Knisely on which filters do best on different well-known nebulae:

Don't take this as the last word though - experimentation can always yield surprising results.
