Filters for visual observing

I have a set of Yulong Optical flters, I have used these for visual observing and also photographic work, they worked well at both. I don’t know what the bandwidth is. Yulong Optical are one of China’s largest optical suppliers. Only selling due to ill health.

These are all 2 inch filters.
