2018 April 23 Sun - prominences on SSW limb
Prominences show up on the SE, NWW, SW, SSW and NEE limb.
This is the prominences on the SSW limb.
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.
