Description

I changed the H-alpha train today. This time the Lunt etalon came first after the TZ-3, after the Lunt etalon the SolarSpectrum ASO. Succesfull combination, no tilt needed for the Lunt etalon, no banding etc. 
Tried a couple of animations today, but the seeing was bad. At the end of the session I looked for the last time if somtehing was happening. And yes: a coronal ejection! Managed to get some good AVI's.
For the very short animation check here:
