Spotless Sun in H-Alpha with Solarmax 3

Again a spotless day but the Sun disk is full of action when looking in H-Alpha (Hydrogen Alpha emission line of 656,28 nm). This morning the sky was very transparent and free of clouds. So ideal to rehearse with the Solarmax 3 70/400 <0.05 nm. Visual observation with 8-24mm zoom show different filaments and prominences. Trying the different setting of the scope show some granulation but more practise is needed.
Great to see that both filaments as prominences are visible in one field view. This was not possible with the PST 40 as I needed to move the sundisk around to see the details.





Furthermore I try to take some pictures afocal using the 8-24mm zoom. Best result was achieved with 14mm and camera setting 1/200s and ISO 1600-2000. The picture was edited using CS4. The picture shows the different filaments aswell as the prominences.
