2018 May 2 Sun - filaments and flare
While there solar surface looks like featureless, a few filaments and a small flare show up.
As the slow motion is still unavailable, I have to continue with push or pull the telescope to put the image in field. This task becomes very tedious when working on close-up imaging, and I have to use very short exposures (thus high gain) to avoid blur images.
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.
