Vent: a guy at the Grand Rapids star party said to skip the light pollution filter and he was right
I dropped $85 on a clip-in filter for my DSLR last spring, then Rick from the local astronomy club told me at a Grand Rapids star party last month to just drive 40 minutes west of town instead, and my shots of the Andromeda galaxy came out way cleaner than anything I got through that filter, so now I'm wondering if I should sell it or keep it for moonless nights at home.
