2018 April 6 Sun

AR12703 is just west of the disc centre. There is no sunspot today.
As the FS-2 controller refused to work, I have no clock-drive on my OTE-150 mount and have to rely on manual push to point my telescope at the Sun.

Telescope: AP Starfire EDT 155 mm f/9.
stopped to 80 mm (f/17.5) for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: ASI1600MM, 4656X3520 pixels (3.8 micron), binned 2
North is up, east is to the left.
