With a sunny day, a photo of our star could not be missing.
Fortunately these days a small sunspot is easily observed, so I took a couple of photographs in full light with the use of a special set of filters.
Unfortunately the air turbulence was high (IV on the Antoniadi scale) but I still tried the recovery.
The wide-field photo was taken in direct focus of the refractor, while for the magnification I used a 3x TeleVue Barlow lens.

Acro refractor ES 127mm f6.5
Herschel Baader Cool Ceramic prism
1.8 Baader ND filter
Baader Continuum filter
Baader uv / ir cut filter
ZWO ASI178mm
Autostakkert and AstroSurface processing
