2018 May 14 Sun - prominences on NWW limb

There are several prominences along the NWW, SSW, SE and SW solar limb.
The one on the NWW limb show changes.

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.
