Thanks for the info., I was wondering how to remove the coatings safely.
True, the solar film is quicker, but this should result in better optics.
It is only cheaper if you already have a scope though.
The main attraction is though, that there are no filters to be damaged, punctured, accidentally removed or fall off for outreach work.
This will be designed for outreach and maximum safety, and also as an example that DIY is possible for schools etc.
