Close to the mill in the previous post, another mill is located.
Coincidentally, it's called 'De dog' (previously Dogmolen) whereas the mill above is called "De Kat" (Dutch for 'the cat'). In English it's Cat and Dog, however in Dutch no meaning like that at all  .I haven't been able to retrieve where these names come from. In the past De Kat was called De Zien, which is the name of the polder it was working for.  NEX-5N, full spectrum converted + Sony 18-55mm OSS + 720nm |

Some experimenting with a CLS filter which blocks the light of the spectral lines of mercury and sodium-vapor lamps (between 540nm and 650nm).

Looks a bit energetic to me, but the colours are great is this with the astro filter again?
I think my light pollution filters are nebulae types which probably cut a wider range of wavelengths. There are huge differences between different versions of these - but I guess I should give mine a try sometime :) |
