If no cover make a cardboard cover and make a 3"= 75mm hole off axis and cover that with the filter film.
Try to keep the filter film as smooth as possible.

I did this with mine the other day. It works really well. I also bought the Baader film and it had instructions with it on how to make the filter itself (by sandwiching it between two pieces of cardboard.)
It's really cool to look at the sun. Although I'm not getting as much detail as I'd hoped for. I think a shroud for my scope will help. But from what I've read, what I want is a H-alpha filter, is that right?
If that's the case, do they do a film that has this?
(sorry to butt in on your thread Greg, but it may be helpful to you as well.)
