Due to various complications with my imaging setup I had to really get FLO involved with working out the required filters. They spent significant time with me on this matter and came through with flying colours. Always superb in their customer service. And the filters are great too and I'm very pleased with them. Highly recommended...

tested at f1.9. This was what my mono hyperstar setup needed.Only had an hour window in the clouds but 30 mins of oii and 30 mins of Ha pulledin alot of data.
It was alot of money but no regrets.
