I am going to make a solar filter for the up coming Mercury transit ,but I don't know which solar film to use ,Baader solar film or Seymour solar film ,can't afford a PST

Ive only used the Badder. I think its what most people use.

I would go for Baader Solar film, ND5.0 for visual, works very well and proven with many people.

Take good care while watching the sun it's dangerous for the eyes and for the scope (if a procedure is not respected has you know).

The mechanic memory of night can cause prejudice when watching the sun. Has an example for me: at night, after an observation with my newton telescope on an equatorial mount, I remove the accessories out from the scope before I put the instrument back to default position, pointing Polaris. I did exactly the same thing after a sun observation, with the telescope still pointing the sun, I removed the baader filter. The sun melted the protective plastic cap on the focuser generating black smoke inside my instrument.

My mirrors could have been destroyed also, or my eye.

--> Huge procedure error for me...

Could be something else too, bottom line, it's really dangerous, the damages can be done really fast.
