The first half of March was very favorable, and it was the first time that I managed observation on 9 consecutive days, from March 04-12. The second half was a completely different story, with observation on March 22 and 23 only.
Here are the images.
Disc0 are images taken BEFORE the filter reaches workbing temperature and thus look like white-light images.
Disc1 images show surface features.
Disc images show prominences on the limb.
Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
North is up, and east to the left
