Fantastic images, love the colour your getting with the thousand oaks filter. I had my first go with a solar filter today, and was just wondering if it's possible to see prominences with an 80ED and the baader solar film over the end apeture?

The suns not particularly exciting right now, no sunspots (or at least none i could see) I tried putting my Ha filter on the diaganol, but that just made everything red, is this the best you can expect without a dedicated solar scope?

You can't see the prominences with a white light filter.

You'll see sunspots (including some detail (http://gallery.orpington-astronomy.org.uk/displayimage-94.html) in them) with a white-light solar filter, but to see some features (like prominences, filaments and plages) you need a very narrow-band filter (1 Angstrom or less) like the one on the Society's solar telescope.
