New Svbony Solar Filter

[sojourneyer]

This is their first entry into this market.

The SV229 complete line of Solar Filters feature renowned Thousand Oaks Optical film in a sturdy, clear-anodized aluminum Cap that are ISO 12312-2:2015 Standard compliant.

 

The price is $30 but they are not yet available at svbony.com or Amazon.

I used TO eclipse glasses in 2017, and everyone agreed they were much sharper than the cheap eclipse glasses most folks had.  I also used to have a glass TO solar filter.  It was good, but not as sharp as the Baader solar film.  That, and it was prone to pin holing, so I got rid of it.

BSF is not nearly as sharp as a Herschel wedge, so there's always room for improvement in full aperture solar filters.

I've wondered if a high quality ERF could be made for white light visual use without a line filter.
