Observation in H-alpha, MgIb2, HeID3, H-beta, CaIIH, H-epsilon and CaIIK.
HeID3 shows the coronal hole, facing towards Earth. It's shape is like a witch flying.
Both H-alpha as CaII show activity.
It was also the first time I used a IR/UV L1 cut filter in stead of the IR cut filter.
Seeing was between 1" and 2,5" (measured with SSM3), Sx/Sy was 1 and tilt < 0,5°.
Software: SharpCap, Inti, JSolex 5.6.1, CS4, AstroSurface.
