Hi all,
Here is an image which I took last fall October 11.
It shows what can be seen on the absolutely bald sun if you look through a large aperture
telescope with narrow enough filter.
The telescope used is Celestron 11 280mm sperture equipped with a full aperture DERF filter
and a very simple etalon - Quark Chromosphere. The image was taken at a slight blue wing shift.
You can see here about a dozen of mini-flares (at least very hot spots) and a few small dark
filaments (small prominences projected at the disk) and numerous spiculaes far from the limb.
All these mini-ative objects are very short living and change very quickly. Very interesting
objects for time lapse imaging.
So, with a telecopes of appropriate size one can hunt for solar active events even during dead
season of the solar activity.

It's very good Valery! I totally agree with you, look close enough and there is always something to see.

Hi Valery...
You caught a lot of small details, and proved that even when quiet there are features to tempt us.
Well done
Brian

Nice image, Valery. I'm looking forward to giving my large aperture kit a good run this spring.
