Sorry Matt - I thought it eventually arrived, but after the event.
Based on my very limited experience with glass filters, one from Thousand Oaks and one from JMB, I would not go back to glass filters now that I have used the Baader solar film. That is not to say that glass filters from those suppliers are inadequate – far from it, they are well made, safe and do a great job.
However, IMHO the Baader solar film has given me better results for astro photography so to go back to a glass filter would be a step backwards for me, especially with the Baader astro photography specific film. Also, with one of the glass filters, I had an annoying reflection but that is probably a fault at my end rather than with the filter.
Scopestuff also sell the C9.25 Astrozap Baader solar filter and have always delivered on time and been responsive to my enquiries. If you want to chance your arm again that is!
Cheers
Dennis
