Did everyone catch this incredible article about what narrowband image filters to use for astrophotography?

It especially dives deep into the value of different image filters and the bandpass of each.

This investigative report about astrophotography filters delves into the optimal bandwidth for narrowband filters used in astrophotography of emission nebulae. Jim Thompson's comprehensive analysis explores improvements in contrast and signal-to-noise ratio (SNR), practical limitations, cost-effectiveness, and the impact of filter bandwidth on overall imaging performance.
