As my new FS2 is still some where between Hong Kong and Germany, I am forced to work without tracking. It is surprising to be able to get some really good images!
10 days after my last observation, AR12297 is right on the SW limb and is still giving a show of eruptions.
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.
