    Unfortunately my existing 4 inch dome doesn’t have a broad enough field of view and I have a vignette when in the housing. I will be investigating my options after Easter.

    When I took test photos on my veranda the fish eye creates a curved background. See pics attached. Does having the correct dome port counteract the fish eye effect? It does focus very close to the dome which is great for CFWA but I need to sort the dome +/- any extension rings
