We have the 1.25 and the 2" NPB Filter and they are just great. A much more natural image than the Astronomik UHC which we have in the 1.25 size. The NPB gives a much more natural colour of stars and doesn't darken the image of the nebulae at all.
It makes the sight of M42 and Tarantula something spectacular.
Without the NPB its like you're looking through a different EP.
When the clouds clear .......You're in for a real treat Harb
