I was wondering if there are filters that are must-haves?
I have nice dark skies and 12" dob and only do visual observing.
I know I definitely need a moon filter, as it is
way too bright to look at.
What types of filters are worth investing in? And are the pricier ones worth it for visual observing?
I like to look at pretty much everything: planets, nebulae, etc.
Thanks
