Details:
It's nice to have something to look at on the Sun after 2 weeks of inactivity !
I used my double stacked PST here with CEMAX 2x barlow.
Then I also used a camera extender to push the focal length to 1200 mm.
See that it gives the PST a new potential at : http://sweiller.free.fr/ and click in Headlines on "A little Revolution for the Coronado PST ! (Sunspot !)"
