Clear skies for Saturday moring, when much to my surprise, when I put the camera on the Lunt LS100 I could clearly see an spraying eruptive prom in progress. It vanished about 15 minutes later. I shot it both on band and in the blue wing of Ha to show it better. Small but sweet!
Here is the Halpha image with the DMK51, reduced to 1290:
And here in the "blue wing of Halpha"
I remember threading in the pressure tuning to do this. Is that right for blue wing?
