I got hooked on narrowband with my ZWO filters that came with my ASI1600MM, but these are in a league of their own. I upgraded to the 3nm Chroma set because I want to image during any moon and under Bortle 5 class skies and the results are breathtaking. With the Ha and Sii you can image during a full moon and with Oiii it’s best to wait for 60 % or less, depending on where your target is. NO internal reflections and nicely packaged with a good report and an extremely high transmission. If you spend 1500 pound on a scope + 1500 on a mount + 1500 on a camera, why use cheap filters?
