Hi,

The NPB
The NPB is the ONE filter to have if you have just one, and now regarded as the top narrowband (UHC type) filter in the world. Judged by renown astro-equipment author Phil Harrington as the best of nine leading competitors in the Astronomy Magazine review "Secret Weapons" (August 2005). With the NPB more objects show enhancement, than any other filter in it`s class, and is also a useful Imaging filter. Visually bright nebula seem to be "switched on" with this top shelf filter designed by Dan McShane, Optical Thin Film expert and founder of DGM Optics. One observer described the NPB as a "UHC on steroids"! And, with ultra durable Ion Assisted Plasma Coating Technology used to produce your NPB Filter, it will provide decades of flawless performance.
It cost me $90 USD ($120 AUD at the moment) and I am willing to sell it for half price $60 + delivery.
Price is firm so please do not offer me less as you are wasting your time because I will not respond.
