Photosphere filter 1.25″ 7.5 nm (enhanced photosphere filter)

The photosphere filter is an auxiliary filter, the telescope should use a baader film or Herschel wedge for proper reduction of sunlight, then you can use this filter for imaging.

The photosphere filter is a narrow band filter, CWL is 540 nm, bandwidth 7.5 nm.

Why use a photosphere filter?

As we know, to image the solar photosphere, we usually use the Herschel wedge to get the best contrast, and maybe add an IR685 filter to improve the seeing conditions. But this is not the best way to image the photosphere.

The photosphere has the best detail and contrast around 540 nm, and with this 7.5 nm photosphere filter you can get impressive detail in solar granulation and sunspots like this one:

where should I install my photosphere filter?

We generally recommend setting up the photosphere filter on a T-mount, as this can also help prevent dust from falling on the camera glass.
