In a previous video, I figured out how much better is the signal to noise ratio from a Bortle 4 zone compared to a Bortle 7 zone. What about narrowband filters? In this video I scientifically test the SNR of a 12nm bandpass Ha filter with a luminance filter. The results may surprise you!

For those interested, here is the gear I use (or equivalent; Orion has discontinued some of their products, so the equivalent skywatcher products are listed). Most of the links are Amazon Affiliate links. Thanks!

I made a free SNR app that can help you know how much integration time you need. It's simple to use! Check it out here: https://deepskydetail.shinyapps.io/Ca...
