Dear observers,

I had the chance to observe the sun spot groups 11130-11132. The last both I sketched in white light at decmeber 4th, 11:30 UT. I sketched the whole sun at 12:15 UT. It is quite intersting to see how filamnets change to protuberances.
Instruments: WL - 8cm f/5 spotting scope, yellow filter, 60x
Ha: PST, 40x

Uwe,

Excellent observations of the Sun and sunspot groups 11130 and 11132. You have captured nice detail within the sunspots and throughout the solar surface. Thank you for sharing it with us all.

Carlos

:waytogo: Nice to see both white light and Ha next to each other.
Is that a yellow "color" filter you used??

hallo Uwe,

good work!
The complete h-alpha sketch is impressive.
I saw the sun yesterday too, deep over a warm house roof -
that´s why the image was "swimming".

Yes. I used the filter because of the false color, which that scope gives.
