36 mm round LRGB+NB filters
Looking to upgrade my 1.25" set as they are too small for my new camera.
I like Astronomik Deep Sky RGB which has higher blue cut off, and therefore I would prefer Astronomik to stay in the same brand, but would consider Baader as well.
Not too keen on the cheaper ones (ZWO, Optolong) and cannot afford the very expensive ones (Chroma, Astrodon).
Let me know if you have a set for sale please
Cheers
