Product Description

Player One 1.25" Photosphere 7.5nmnm Filter For Solar Granulation and Sunspot Details

Note: Photosphere filter is an assistant filter, telescope must use Baader film or Herschel wedge for adequate reduction of sun light, then you can use this filter for imaging.
Why to use a photosphere filter?
As we know, we doing solar photosphere imaging, usually use Herschel wedge to get best contrast, maybe add an IR685 filter to improve seeing condition. But, it’s not the best way to shoot photosphere.
Photosphere has best detail and contrast at almost 540nm, with this photosphere 7.5nm filter; you will be able to get some impressive solar granulation and sunspot details.
Features:
1. Player One PS125E filters using high quality optical glass substrate and multi-layer composite coating technology, which has excellent optical performance in astrophotography.
2. Photosphere filter is a narrowband filter, CWL is 540nm, bandwidth 7.5nm.
3. Photosphere filter is an assistant filter, telescope must use Baader Solar Filter or Herschel wedge for adequate reduction of sun light, then you can use this filter for imaging.
4. Usually, we recommend setup your photosphere filter on T-mount; this also can help you against dust drop on camera glass.
