First post here!
So I am considering trying out some deep sky imaging, but before I start spending any money, I need to know if I can overcome one, potentially big problem.
I live right under the so-called "aurora oval" at 69 degrees north here in Norway.
Clear skies without any northern light are rare, even at solar minimum that we have now.
One thing that may help is that NL is not very static and doesn't necessarily cover all the sky or last all night, so I assume I could go for more exposures and just pull the "greenest" pics out of the stack?
But I still think some sort of filter would be beneficial for me, but what should I be looking for? Wavelength etc?
PS, I am aware some may think it's inane to call the beautiful NL a "problem"
And I can assure anyone that I love to observe NL, and also take pictures of it, but now I just want to try out something new
