I think I know that table. I don’t reference it so much with narrowband although in imaging M8 I went for slightly shorter subs to keep the core somewhat resolved. I think the 800mm focal length of my f4 Newt is a good match for the camera in terms of arc seconds per pixel so feel like I’m getting the most out of it too.
