Please note: Agena only sells DGM's "first quality" filters. However, it is our experience that even their first quality filters often have pinholes, sleeks, and/or light scratches. These flaws will have no impact on optical performance and the spectral characteristics of the filter are not compromised. DGM occasionally sells "cosmetic seconds" via their website. We do not sell DGM's cosmetic seconds but please be aware that your first quality DGM filter purchased from us might still have some minor pinholes, sleeks, or light scratches. Despite these imperfections, we believe that DGM filters offer a great value at their price point.
DGM Optics O-III Oxygen Filter in a mounted 1.25" filter cell.
The DGM Optics HP-OIII is your perfect compliment to the NPB when you need a more aggressive Nebula filter that really shines with larger scopes. This filter has a bandwidth of approx. 15nm for those faint, elusive objects, but also has a feature that most other OIII filters don't with high transmission at H-Alpha. For a visual OIII filter this is important as it provides a bit more "optical throughput" than leading competitors. As with all DGM Optics filters durable Ion Assisted Plasma Coating Technology ensures an ultra-hard, low scatter coating.
