So... in a few weeks, Neowise will be visible on this side of the planet.
Like everybody else, I'm getting ready to image it, and suddenly I'm unsure whether to use the CLS filter or not.
On the one side, part of the coma emits light due to ionization, as I understand it. But part of it doesn't, as it's just dust.
So, is using a CLS filter worth the trouble or will it hurt more than it will help?
I'll be shooting way low on the horizon so I'll be aiming at the thickest LP in my neighborhood. That makes me lean toward using the CLS filter, but I'm still unsure. I've never imaged comets before.
BTW, by then it will be much dimmer. Otherwise it would probably be moot, since right now it's visible naked eye. But by the time it gets to be visible over here, it will be magnitude 11.5 and decreasing, so I gather the filter will matter by then.
