5 of 5 Excellent Complement to O-III and even UHC type October 5, 2019
Reviewer: Stephen R. Waldee from Ivins, UT  
I have been using the NPB in conjunction with 5 to 6 other nebula filters for about 2 years.  The NPB is often better on some very low surface brightness PNs, in my 5-11 inch scopes than the standard O-III.  NPB also works at rather small exit pupils where the O-III is way too dim.  NPB gives a 'different view' of multiband nebulae than strict O-III or UHC types; it's especially interesting to see objects that have both emission and reflection neb'y, such as M-20.  I am 100% satisfied with this product, and almost immediately also ordered the 2.0" version too.  I now find it ABSOLUTELY ESSENTIAL!
