Title: Orion UltraBlock NarrowBand Filter
Review: Finally had clear skies and used, for the first time, my new Orion UltraBlock NarrowBand Filter last night on my Celestron 8SE using a 17mm eyepiece. Plenty of urban light pollution. While it seemed to make viewing the Ring Nebula more difficult, it did bring out the form of the Swan Nebula (M-17), against a blacker sky. Without the filter, M-17 barely, or hardly appeared, as just a wispy cloud, against a star-filled grey sky. With the filter, there it was! Viewing with this filter was better than with the O-III filter.
Is the review positive or negative?
