2020 November 22 Sun - prominences on the NW solar limb

As I am now using a straight-through B1200 blocking filter, I have put my H-alpha and Ca-K images as follows:
north is up, east to the left.
Sunspot count: group=3, sunspots=6, R=36

For H-alpha images:
Telescope: Lunt LS50T with B1200 blocking filter
Camera : ASI174MM
2X barlow for some images
exposure: 9.0 - 20.0 ms

For Ca-K images:
Telescope: Sharpstar AL-80 II, 8 cm f/6.25 APO refractor
Camera : ASI174MM
focal length : 500 mm f/6.25
filter: Lunt Ca-K Module B1200
exposure: 8.3 ms
