Compared with a Lumicon UHC 2", I prefer by far the NPB. I believe this filter is a must. Review: Too dark and red ghost images - My review is for the 1.25 inch DGM NPB filter. I had detailed views of the Orion Nebula, but this filter was a bit too dark for anything else with my 4.5 inch reflector. Also, this filter created annoying Red ghost images of stars. Even though this filter is highly rated, I took away 3 stars, because it just didn't work well in my 114mm f/4 reflector. ## Features - 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. 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ITTLKEY | | Best Sellers Rank | #283 in Telescope Filters | | Brand | DGM Optics | | Coating Description | Ion Assisted Plasma Coating | | Customer Reviews | 4.2 4.2 out of 5 stars (6) | | Enclosure Material | Optical Glass | | Item Dimensions L x W | 2"L x 2"W | | Item Weight | 0.3 Ounces | | Manufacturer | DGM Optics | | Special Effect | Neutral Density | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** DGM Optics - **Coating Description:** Ion Assisted Plasma Coating - **Material:** Optical Glass - **Photo Filter Effect Type:** Neutral Density - **Product Dimensions:** 2"L x 2"W - **Water Resistance Level:** Not Water Resistant ## Images ![DGM Optics 2" NPB Nebula Filter - Image 1](https://m.media-amazon.com/images/I/51fnxqkBXhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ brilliant stars or polluted skies *by J***S on November 9, 2015* This filter really blocks unwanted light from moonlight, brilliant stars or polluted skies.
