Dear friends,
Here are some FD images from September 14th. AR2866, 2868 and 2869 are departing and the sun is turning rather quiet again. I spent a good part of the day testing different setups and below are some of the resulting images. All the images have been heavily downsized for this forum, but the full resolution files (the larges ~43MP) can be viewed through their respective links.
FD image in H-Alpha using a Coronado 60mm/BF15 w/Beloptik ITF, stopped down to 50mm, Baader 35nm H-Alpha and ASI 178mm mounted on a SkyWatcher SolarQuest.

Longer exposure to bring out the prominences a bit better.
