The Paradigm Dual ED eyepieces or telescopes are known for using extra-low dispersion (ED) glass elements to minimize chromatic aberration and improve image clarity. The term “poor glass quality” could stem from a few potential issues. One possible concern might be the production variability, where occasional units may not meet quality standards due to manufacturing inconsistencies. It’s also worth considering that user perception can vary, as some might compare it with higher-end optics that utilize even more specialized glass materials and coatings.
If you suspect that the glass quality is subpar in your Paradigm Dual ED product, it’s advisable to first ensure that you are using it in optimal conditions and with proper settings. Factors such as dust, physical damage, alignment, or improper use could also affect perceived image quality. Furthermore, contacting the manufacturer or vendor for support or a replacement might be necessary, especially if the unit is under warranty. They can offer insights or corrective measures like alignment checks, cleaning tips, or direct service options.
