Description

Three images of the partia solar eclipse on 25102022. A lot of clouds, still great fun. 
I used a new H-alpha train, the PST etalon is changed for a front etalon that came off a Lunt 40mm H-alpha telescope. So it now looks like this:
Baader D-Erf 180mm
180 mm Intes M-703 (f/10)
Baader 3x telecentric TZ-3)
SolarSpectrum ASO 0,5
Lunt 40mm etalon
Astronomik UV/IR block
PointGrey Grasshopper IMX174

It looks promising. The double-limb effect is gone, but still missing the centre line of H-alpha. Something for next season!
