Sunspots: FZ38 vs NASA
1

I recently posted (here ) a shot of the sun taken using the Baader solar film with my ZS30 plus Nikon E17ED TC.

I tried some further tests with the Baader film using my FZ38 plus stacked Nikon TCs. Since a yellow-green filter (Wratten No 11) is sometimes used with telescopes to improve contrast, I tried that filter in my setup.

I found that the filter did seem to improve the definition of the sunspots. This is a shot using the filter:

Daily sunspot images are provided on the NASA site here . This is the daily sunspot image for 19 Sep from the site:

When viewed at full size, my image seems to show all of the sunspots on the NASA image except for the one labelled 1847.
