Filters for a DLSR

[lineout]

This is probably a very basic question but how do I use astro filters with a DSLR? Do I need a special holder or will the screw into my T-adaptor?

Hi

Just make sure your T-Mount adapter is threaded for 2" threads on the front and use 2" astro filters, easy.

Something like this is what you are after:
