I'm dreaming...

I didn't come back for several months because I never had my hands on my telescope for some time.  Night time traveling could be quite difficult right now and day time observation is very limited, too.

Now, I wanted to buy a H-alpha solar filter for myself again.  Any good suggestions?

I've a single requirement: cheap, I don't need something powerful.

I don't mind 2nd hand, DIY, hacking or whatever.
