This seems like an amazing solar telescope but the price is going to not make it very popular for every day solar astronomers. I have a 90mm Coronado SM90 Etalon and BF-15, USA Made, it this pretty much taps out my budget at about $2k. Im big on Solar Astronomy but even the white light filters are nice in larger telescopes for really seeing sunspot details.
I cant imagine any solar scope or filters being very popular above about $3K in cost for most astronomers unless of course people are dedicated solar observers.
I hope these sell well however. Larger filters, just like larger telescopes, really allow for higher magnifications for visual observers. Of course, with astrophotography, even small filters can look impressive with Photoshop.
