Hi all

I'm a fan of diffraction spikes, and would like the option of adding some to my widefield imaging through the ED80/350D.

What's the best way of making some sort of fishing line arrangement that I can put over the objective end of my ED80 to achieve this?

How thick should the fishing line be? What size does the holder need to be to fit around the dew-shield of the Saxon ED80?

Suggestions welcome.
