Default Viewing Sun with Baader Solar film

Hi All,

With Baader Solar Film, Will I be able to see Granular view of Sun
and Dark Spots?? I have Celestron 127 Power Seeker telescope.


Yes. You will see bright faculae as well. How much detail you see will
depend on the atmospheric seeing so some days are better than others.

Always check it for pinholes before use and make sure there is no
possibility of the filter falling off or being blown away by the wind.

Have any one used baader Solar film with Baader Solar Continuum
Filter.. With this combination Will I able to see granule and flare/
Prominence ??


To see prominences you need a narrow band H-alpha filter with a FWHM of
better than 2A (0.2nm) the better ones these days are 0.7A (0.07nm) at
which point you need to tune it to allow for Doppler shift as well.

It is easier to see prominences on the limb with the wider band 2A
filter but to see any H-alpha detail on the disk you need the narrower
0.7A (more expensive) filter. The disk is too bright otherwise.
