Scorpio Astro 36mm Ha Filter Astronomical 3nm Ultra Narrow Band Telescope Filter without Lens Frame
How to choose:
- 3nm SHO: Especially in the case of strong light pollution, or for the resolution of the finest detail the narrower 3nm ultra-Narrowband filter is the better choice (F4.8-F16).
- 5nm SHO: If you plan to use the filter on several telescopes with different focal ratios (F4-F16) and want a good signal-to-noise ratio, the wider 5nm Narrowband filter is useful.
Description:
- It is an ultra narrowband filter designed for deep space photography with mono cameras.
Features:
- No halo design, maximizing the elimination of halo effects on imaging.
- SHO LRGB parfocal, high efficient shooting, reduces frequent focusing.
- Peak transmittance of 90%, higher shooting efficiency and image contrast.
- High cut-off depth, with an average of OD4.5.
- Edge extinction, chamfering, further reducing stray light.
- Ion beam hard coating, with a harder surface, easy to clean and less prone to scratches.
- Professional design to prevent urban light pollution.
- Glass thickness of 2mm ± 0.1mm.
- ±0.1nm precise bandwidth control
- Maximum support for F4
- Support mainstream filter wheels
Package Included:
- 1 x 36mm Ha Filter
