Hello, please share your impressions of the ZWO Duo Band filter.
Was there an opportunity to compare it with OPTOLONG?

Hello. Unfortunately, I don't have any Optolong filters yet, but with the Duo-Band filter, the frames come out better than without it. You can compare it with my slightly earlier image of C33 - there, the only filter used was a UV-IR Cut.
